The LiPo’s in the video are mostly 7S 4500mah; similar energy density as a theoretical 6S 5250mah pack. I can balance charge between 36 and 38 of those 7S 4500mah from about 20% (3.84V/cell) to 100% capacity (4.20V/cell) before my 24V 200AH LiFePO4 bank is depleted.

@@johnahamelv Impressive! Then only two LiFePo4 in series should serve me well as I don't fly more than 12 packs a day. Thanks for the info!

@@janriggert Another option is to use a single 24V 100AH LiFePO4 battery. I did not go with this option myself mainly because it was heavier on my back than I wanted and and it was more challenging to stow away in my car due to its bulk, but your circumstances may be different than mine.

The manual states the USBC port outputs 5V/3A, 9V/2A, and 12V/1.5A. So somewhere between 15W and 18W. Considering the maximum input current is 70A, even the much smaller EC5 connectors (rated for about 120A) would suffice. The EC8's are way overkill. Wether to leave the EC8's as is or replace them with other connectors is just personal preference, but no impact on performance.

@johnahamelv I guess you own one? Do you like it?

@@CR3DT So far so good. Same compact size as the 308Duo and with a few improvements. The 308Duo was limited to 30 DCV input; this 458Duo can accept up to 49 DCV input. Further comparing the 308Duo to this 458Duo, the charge current increased from 30A per channel to 45A per channel. Balance drain increased from 1.2A to 2A; This may not sound like much, but it translates to 67% increased balancing speed. Improvements that I would to see include: 1) Ability to program from a PC/tablet/phone. This would allow for much faster programming compared to the current method of using the rotary knob and going through multiple screens. 2) Find an alternative to the rotary knob. The potentiometer tends to wear over time. I already had three iCharger Duo chargers (one 308Duo, and two 4010Duo's) where the rotary knob eventually became intermittently responsive. You can get replacement rotary knobs from Progressive RC for only $5.00 each, but you have to feel comfortable desoldering the faulty knob and soldering the new multi-pin potentiometer knob onto the mother board, which is not for everybody.

I continue to fly with VBC radio. I honestly have not experienced any issues at all during flight. I just wanted to demonstrate this "bench" issue in case someone else experiences the same issue. This is an issue that happens only at the bench when the radio is in close proximity to the charger/power supply, but this is not an issue at all when radio is not in close proximity to the charger/power supply.

Yes. I preordered a red Spirit WAVE radio and a Spirit W1 units to start with. As far as overall flight performance, I cannot distinguish much difference between VBar Neo/EVO units vs Spirit units AFTER proper tuning. Both the Neo/EVO units and Spirit units default values are quite tame, so you really need to take your time tuning them to reach their potential. I enjoy the interface of the Mikado VBC Touch and EVO radios with the Neo/EVO unit much better than the Jeti/Spirit interface. I actually do not currently have any Spirit units in my helicopters mainly due to the clunky Jeti/Spirit interface, especially in comparison to the VBC Touch/EVO with Neo/EVO interface. Both the Jeti/Spirit and VBC/Neo/EVO have their own pros and cons. The Spirit WAVE/W1 has the potential of concentrating the best features of Jeti/Spirit and VCB/Neo/EVO with none of the disadvantages of each. The WAVE radio come stock with the coveted AG01 gimbals. The VBC Touch/EVO radios have built in WiFi, but it is limited to the 2.4GHz band. The WAVE radio's WiFi is the more modern 2.4GHz/5GHz dual band. The WAVE radio also features BlueTooth. Whereas the Mikado VBC is mostly a 100% close system, the WAVE radio allows for community created Lua apps, similar to Jeti. All three radios (VBCT/E, Jeti, and WAVE) feature internal motion sensors. Mikado does not currently allow for use of these internal motion sensors. Unlike Jeti which charges to unlock these internal motion sensors, the WAVE radio will allow use of these motion sensors, and at no additional cost. The list goes on and on for the WAVE radio.

@ thanks for the detailed reply. I think I might got for the spirit wave. I'm in the UK so could have it next day delivery for the Red standard version! One thing that still tempts me with the VBar is the new mikado cap pack. That's seems so simple. Hopefully Tomas will follow with that

@@atcoflyer1756 I've had a pretty good performance experience with VBar since my first VBar Silverline in 2012. Neat bells and whistles and convenience features have been added since. However, Mikado hardware has room for improvement. I did run into issues with one VBar Silverline where the sensor malfunction during flight leading to a minor crash. I had to send the the unit to Mikado in Germany for warranty repair. Mikado mentioned that the sensor was damaged due to the crash. I explained that the sensor malfunction is what led to the crash. Mikado ultimately sent me a replacement unit, but the bad taste remained. I left Mikado VBar for a few years and went back to VBar in 2018 with the release of VBC Touch radio. Not even Jeti/Spirit can rival the convenience and intuitive simplicity of the Mikado ecosystem. However, Mikado hardware continues to lag behind. For instance, I've had way too many Neo/EVO plastic cases with broken retaining tabs, that I consider a replacement aluminum case worthwhile. Then one needs to consider hardware limitations. Even though the VBC Touch radio was released in 2018, the internal memory was limited to about 266 MB; contrast that memory to other radios especially in that price range where memory is measured in GB terms. The new VBC EVO radio does have memory in the GB range, but this should have been the case with the 2018 VBC Touch as well. Same goes for the Neo flight controller. The Neo cannot support 760µs center pulse for cyclic servos because of hardware limitations. Contrast the Mikado hardware with Spirit. Starting with the original Spirit flight controller from around 2015, all Spirit flight controllers feature an aluminum case which fasten the PCB board firmly. All early Spirit units can handle 760µs center pulse cyclic servos. Except for the Spirit units with integrated Jeti receivers (RS and GTR), all Spirit units can handle a 3S LiPo, so they have been ready for 12V servos even before 12V servos became a thing. Consider Brain2/iKON2 as well; the hardware is >8 years old, and they are capable of handing 760µs cyclic servos. The point here is that Spirit and Brain2/iKON2 have pretty reasonably future-proof hardware, whereas Mikado generally require purchase of new hardware (and accompanying costly firmware "upgrades") to keep up with advancing technology. This brings up another point; cost of firmware upgrades. All Spirit and MSH Brain2/iKON2 units come with all features unlocked and they have never charged for firmware updates or upgrades. In contrast, Mikado flight controllers come with a basic firmware which requires payment to upgrade. A recent Facebook poll demonstrated that 98% of VBar pilots upgraded their Neo/EVO units to either Pro or Pro/Rescue. As far as the Mikado capacitors, I applaud Mikado for this effort. These capacitors are 12V capable, and use similar circuitry and XGuard RC capacitors, and they have simple plug-n-play integration with VBC radios. I am not sure it may be worth it for Spirit to create their own capacitor buffers. It may be more time efficient for Spirit to create an app for similar plug-n-play telemetry integration with exisiting XGuard RC capacitors, or just have a knowledgeable community member to create a Lua app for the WAVE radio for XGuard RC capacitor integration. Truth be told, I just use the XGuard RC capacitor buffers with my VBC EVO without utilizing its 3rd wire integration capabilities, but I am aware that some folks really like the configuring the radio to take advantage of the XGuard RC capacitor integration.

@ thanks John. It's such a difficult decision to choose between the two! I really appreciate you explaining your view and the facts on both. I think the wave will take first place due to the hard deck and better tech. Also I think the customer service is better too. Tomas replies very quickly on the forum or via email. I emailed mikado Germany directly a week ago and haven't had a reply, to me that speaks volumes!

@@atcoflyer1756 The Mikado developers only respond the Mikado forum. I've never seen them respond in Facebook, HeliFreak, or any other social media. Tomas tends to respond not only on the dedicated Spirit forum, but also on Facebook and HeliFreak. My experience with Mikado's responses in the Mikado forum is that they tend to respond mostly on weekdays. They occasionally respond on weekends, but it is certainly not as likely as weekdays. The Spirit WAVE is in a similar category as Mikado, meaning both ecosystems are helicopter-centric. Mikado is a pretty much a 100% close system in that all functionality is 100% dictated by Mikado. This has its advantages and disadvantages. The Wave radio shares similarities with the Jeti radio in that the operating system is proprietary, but the system allows for community-generated Lua apps. These Lua apps add functionality beyond the developers' imagination. This is important to me. There are many features I would like Mikado to add to the VBC radio, but Mikado generally refuses to add them, as they believe such features are either unnecessary or they feel there are already existing solutions to solve these concerns. For instance, Mikado took away the ability to center the tail servo arm around version 5.2 of the VBar firmware, and they refuse to bring it back, as they consider it unnecessary. Another example is how VBC announces the battery capacity remaining; the VBC radio announces the battery capacity remaining in 10% increments. I asked Mikado to allow for an option to announce the battery capacity at 5% or 3% remaining as well, as this would allow me to do an autorotation and land at exactly 0% capacity remaining (0% announcement generally means 3.74V/cell the way I configured it). Mikado refuses to offer this option. In comparison, other systems including Jeti and WAVE allow for customization of battery capacity remaining. These are just 2 examples.

Thank you for the explanation. I presented the observations, but now I understand the "why". Thank you very much!! 🍻

That's what I think. The charger/power supply most likely created a magnetic field that ultimately caused this inappropriately responsive touch display issue. This also happened with my flying buddy's touch display as well, so very reproducible.

@@johnahamelv Is this only for touch versions or does evo have this problem too? I hope it doesn't cause any problems flight.

@@mr.e3d I tested this only with 2 "Touch" radios. I have not tested this with the EVO radio. I never encountered any issues during flight with either the Touch radio or the EVO radio. I am generally pretty far away from the LiPo charger and power supply when flying the helicopters. I have not tried flying my helicopters with the radio in close proximity to the LiPo charger and power supply. I no longer have the "Touch" radio, but maybe it will be a fun project to test different charger/power supply proximity variations with the EVO radio.

Like you said, it is quiet and no exhaust. No gasoline spills either. No gasoline smell in the car. No need for maintenance either, like keeping track of oil changes and spark plug replacement. No need to DC power supply either as the charger connects directly to the LiFePO4 batteries. Each individual mini size LiFePO4 100Ah batteries weighs only 19.5 lbs., compared to about 65 lbs. for a 2200W inverter generator.

Yes. I plan to get the Spirit WAVE around Christmas time. I plan to post a video mai. comparing the WAVE radio vs. the Jeti radio as they relate to Spirit, but yes I also plan to publish another video comparing the WAVE radio vs. VBC EVO radio as these would be the only two helicopter centric radios in the market. I’ll compare the stock VBCe gimbals vs. the WAVE AG01 gimbals, their touch displays, their speakers, WiFi connectivity, ESC programming from the radio, etc. I’ll also cover what can be done with the WAVE radio motion sensors. I’ll spend some time covering the WAVE W1 vs. EVO units to include design, construction, number of ports, etc.

@@johnahamelv Hi John, I will wait for your review and then decide for the vbar or the Wave.

I read and re-read what you stated above a few times, but I am having a difficult time understanding what you mean. I am not familiar with the "old Align pitch rod" or what you mean by the "saddle of the head". What is the "slot" you are referring?

To further clarify this point, it is actually best to use an appropriate diameter long bolt rather than an hex driver. I used a hex driver in the video because I did not have a long M5 size bolt for the video. The hex driver I used in the video was mainly to visualize the concept. The hex driver fits too loosely with too much play within the blade grip bolt hole. You really want a "long" bolt of appropriate diameter for the blade grip hole.

I just added weblinks to the related Tinkercad page

Hello Greg. It was nice seeing you at Spring Fling as well. No Fall Mowdown for me this year, but I'll make it to this IRCHA 2024 next month. 😀

these brands predate drone age. and mostly designed for traditional Radio Control airplanes and helicopters. Graupner, JR Propo and Futaba were the big names in RC electronics.

@@davidjacobs8558 Makes sense. I watched RC from afar over the years. I discovered a year ago that FPV acro quad flying is my happy place.

I do NOT fly multi-rotors, quadcopters, or FPV. I fly exclusively 3D RC aerobatic helicopters, so all my RC videos are from the point of view of these 3D RC aerobatic helicopters. The Mikado ecosystem is very popular in the world of RC helicopters. Although it can be used for fixed wing, this Mikado system is generally considered the only RC helicopter-centric ecosystem in our side of the hobby. Jeti is more popular in the fixed wing side of the hobby, but it can be configured to work with helicopters, multi-rotors and other RC disciplines. The Open Source systems are gaining popularity in the 3D RC aerobatic helicopters side of the hobby, but the interface and ease of use is not considered as mature as that of Mikado.

I too have felt that way since the VBC Touch came out. The Neo and now EVO units are good to very good, but they are not excellent. I find the Spirit units, specially the GT/GTR next level compared to Neo/EVO. However, to get the optimal experience with Spirit, Jeti radios are arguably at the top of the list. Jeti radios pack a lot of features (after you unlock the paid modules), but a lot of these features are best suited for fixed wing, and do not really apply to helicopters. The VBC Touch and now EVO radios are good to very good, but again not excellent. However, when you pair the Neo/EVO flight controllers with a VBC Touch/EVO radio, that's where I feel the whole is much more than the sum of its individual parts. I prefer the overall general experience with Mikado as a whole than with Jeti/Spirit. I really look forward to the Spirit WAVE system, as this will be the first competition of its kind that Mikado will face. I am also intrigued about the JR flight controller still in its testing phase, but as good as JR radios are, just like Jeti, JR is fixed wing centric. It seems Open Source radios and flight controllers are gaining in popularity, for what I assume is the very affordable price and and the features and possibilities limited only by the programmers' imagination, but I would need these Open Source systems to have improved user interface before I tackle something like that. I do see me trying open source equipment in the future, like in maybe 2 or 3 years from now, but I am not ready and/or willing to take on that challenge at this time.

I have seen a fair number of pilots "with money" switch to open source systems like RadioMaster and FrSky. Besides the attractive price, Open source does offer capabilities only limited by the collective imagination, whereas with more closed systems, capabilities and features are limited by the imagination and preference of the few developers. I am very interest to learn Spirit's approach with its upcoming WAVE ecosystem. This is more a semi-close (or semi-open depending on point of view) system, where the operating system and firmware is closed, but it still allows for community generated Lua apps (similar to Jeti and other systems) that serve to enhance the overall experience beyond the developer's imagination.

There is a growing enthusiasm for Open Source technology. I do envision Open Source transmitters gaining a bigger piece of the pie over time, but we are just not there yet, at least not in the 3D helicopter discipline of the general RC hobby. At the present time, both the VBC and Jeti radios are quite popular in the 3D helicopter hobby as seen at any given fun fly in the US.

I don’t like wearing a neck strap. I felt I needed to wear a neck strap (actually a body strap) with the DS-14, DS-16, and specially the DS-24 radios because they were noticeably heavier. I don’t like how the aluminum shell feels pretty cold on my hands during the winter months. That’s why I sold all my other Jeti DS radios and settled for this light weight DS-12 radio. I also fly only helicopters, so the DS-12 has all the functionality needed for the 3D helicopter discipline.

@@johnahamelv makes perfect sense.

Looking at US market, the VBC EVO radio is currently sold exclusively by Mikado USA. shop.mikadousa.com/VBar-Control-EVO-Pick-Your-Color_p_3021.html The current list prices for a standard black VBC EVO radio is $1,299.99. There are options to purchase the radio in certain colors that bring the list price to $1,399.99, and some special colors bring the price to $1,499.99. Once you purchase the radio, you have the option to upgrade the radio's software to a "Pro" version for an additional $50.00. For the Jeti DS-12 radio, the base model lists for $650.00 and the carbon edition (the one in this video) lists for $975.00. To unlock features, Jeti has you pay additional money for modules. You can purchase those modules individually a la carte, or you can purchase them as package deals. A fully unlocked base model DS-12 radio lists for $1,025.00 and a fully unlocked DS-12 carbon edition radio lists for $1,375.00. www.espritmodel.com/jeti-duplex-radio-systems-ds-12-2-4ghz-900mhz-line.aspx

Definitely. I never felt the older iCharger 308 or iCharger 4010 needed additional charging power, although I am glad there is more balance power now for faster balancing. But yes, a more modern UI would have been neat.

The Tron Dnamic and XLPower Specter V2 are in different categories of helicopters. The Tron Dnamic is a "light weight" 700 size helicopter designed to be flown with a single 6S to 8S LiPo pack and meant to be flown at relatively lower head speeds. The Tron Dnamic is best compared to other helicopters in its class like the SAB Goblin RAW 700 Piuma and maybe the Oxy Flash. The XLP Specter V2 line of helicopters are designed as full size 700 size helicopters. The Tron equivalent to the XLP Specter 700 V2 airframe is the original Tron 7.0 and the latest Tron 7.0 Advance. Between the XLP Specter 700 V2 NME and the Tron 7.0, I prefer the Tron 7.0 overall. Even after upgrading the XLP Specter 700 V2 NME to the latest WC edition, I no longer own the Specter V2, but I flew the 368th flight on the Tron 7.0 just today. That hopefully gives you an ideal how I much prefer the Tron 7.0 to the Specter 700 V2.

@@johnahamelv Thanks man. Have a nice flight

Thats Mikado s philosophy - plastic's fantastic 😁

My best guess is flight logs are mostly reviewed at the field, so ready access to the flight logs right from the radio is most convenient. I plan to publish another video demonstrating reviewing of flight logs via the Mikado VStabi website vs using Jeti Studio.

I cannot answer that. I have never tested the servo testing function in any of my iChargers.

I've never tried it myself, but I believe this can work for the AUX2 port. On the PC program, go under the General tab >> Channels. For "Function", choose "F: Output to AUX2" and assign a channel to this function.

I was not aware that HRB made an 8S LiPo battery. I am not having much luck finding this HRB 8S 3800mah LiPo battery on google.

Hello Gary. Thank you for your support. I fly 3D helicopters exclusively, so I always use heading hold. I believe the scale helicopter pilots like using rate mode for a more "scale look", but I admit that's about the extent of my scale helicopter understanding. It is my understanding some folks like adjusting the tail rod length using "rate mode" for mechanical setup purposes, under the belief mechanical adjustment under "rate mode" will make the tail hold better when using "heading hold". This theory has been debunked by the FBL unit developers (Tomas from Spirit, the MIkado developers, the MSH Brain2/iKON2 developers, etc.), but misinformation continues. From a pure academic standpoint, yes it is possible to flip between "heading hold" and "rate mode" using a switch. You would need to use "Free Mixes". This is found under "Main Menu" >> "Fine Tuning" >> "Free Mixes". You have to create 2 free mixes. I confess I don't fully understand why this works, but it does. You need to set up the 2 mixes equally. From Gyro sens. To Gyro sens. Set Master Value to "-100%" on both mixes. Set up the same activation switch and in same activation mode for both mixes. I don't have a video for this setup, but you can refer to this troubleshooting video. kzbin.info/www/bejne/mGqtoJqbdrqlhpI If you plan to use this method, make sure to assign Rescue/Stabilisation to a separate channel along with a separate switch.

Thanks John appreciate the quick response

I never figured out the aileron shakes with this Synergy 806. I sold the airframe. The buyer did not run into any aileron shakes issues, but I don't know what he did differently. Like you, I also ran into similar aileron shakes with the Tron Dnamic. A combination of loosening the main blades and lowering the head gains down to the high 30's% to low 40's% did the trick.

True. Now the question is whether this thrust bearings installation orientation should also apply to other helicopter brands builds as well??

Seems it should be as other brands recommend as that would ‘somewhat’ aid in the retention of bearing grease.

80W per channel or 140W combined. I personally do not discharge using the charger's internal heat sink bank. I prefer using dedicated dischargers.

@@johnahamelv Is that because of the heat? Maybe harmful to the fets?

@@fredericktodd5789 I do not have formal education on electronics, but it does not seem like a good idea to me to heat up the internal heat sink of a charger to discharge batteries. I use my chargers just as chargers.

The Dnamic has a 700 size tail in the back is generally outfitted with relatively light weight motor and ESC in the front. When fitted with a single pack in the front (6S 5000mah, 7S 4500mah, 8S 4000mah), the fore/aft center of gravity is optimal. I imagine using the using two 6S 3700mah in stick configuration would inevitably shift the center of gravity towards the back. I don't know if it would be possible to shift the 12S 3700mah pack foreward enough under the canopy to obtain an optimal fore/aft COG.

Thanks!

Of the two chargers (458 Duo and 4010 Duo), the 4010 Duo has been around for about 10 years, so it has a proven record. However, it is my understanding that later versions of the 4010 Duo components have been updated over the past few years as older components were no longer available, so who knows how the newer components compare to the older components. Since the largest cell count batteries I charge are 8S, and the fastest I charge is 27A/800W per channel, the more compact 458 Duo makes the most sense for me. I guess the real question is choosing between the iCharger 456 Duo vs. iCharger 458 Duo. The iCharger 456 Duo is a bit cheaper at $325.00, but it has a 6S LiPo cell limit. The iCharger 458 Duo is $25.00 more expensive at $350.00, and it has a LiPo cell limit of 8S. Since I charge 8S batteries, the 456 Duo is not even an option for me. Still, for the $25.00 price difference, I would still recommend the 8S capable 458 Duo over the 6S capable 456 Duo. Since the released of this video, Junsi released the next generation charger to the 4010 Duo, the iCharger 4512 Duo. This iCharger 4512 Duo is the same physical size as the older 4010 Duo, but it features some of the same updates as the 456/458 Duo chargers, and it is capable of 53V input (compared to 49V input for the 456/458/4010 Duos). This 4512 Duo would be the choice for charging12S batteries (with 12S balance connectors). As far as power supplies, I personally prefer power supplies from reputable companies, and I always look for power supplies with active Power Factor Correction feature. My preference is the MeanWell RSP-2000- either in the 24V or 48V versions. A close second is the Junsi/Chargery S1200 or S1500 power supplies. www.progressiverc.com/collections/24-27v-supplies/products/mean-well-rsp-2000-24-power-supply www.progressiverc.com/collections/48-54v-supplies/products/mean-well-rsp-2000-48-power-supply www.progressiverc.com/collections/24-27v-supplies/products/chargery-s1200-power-supply www.progressiverc.com/collections/24-27v-supplies/products/chargery-s1500-power-supply

Ok so my next question is what do u think the best charger on the market today is. Thanks for ur reply

I currently have a k2 air but it lacks a lot for sure

@@AaronBittenbender The ISDT K2 Air is nice and compact size. It is AC/DC, so it gives you the option to connect it straight to the wall outlet and charge up to a limit of 200W. This works pretty well for charging several 1S, 2S, and 3S micro size batteries in parallel without needing an external power source. With an external power source, it allows for charging up to 500W per channel, which is pretty good. I would pair it with a 1000W to 1200W 24V DC power supply or LiFePO4 batteries.

@@AaronBittenbender This really depends on your situation, and budget. For me, mainly charge 7S 4500mah and 8S 4000mah packs and occasionally 6S 1800mah packs. This iCharger 458 Duo is to me the best compromise of existing chargers in the market today for my situation. Tell me more about your current and expected future charging needs.

Neither system is perfect. I find Spirit faster to tune to my liking than Neo/EVO. The Jeti radios offer many features not available with the VBC radios. However, the VBC Touch/EVO radios paired together with Neo/EVO FBL units are more than just the sum of the individual components. I mean, I prefer the Mikado ecosystem user interface better than the comparatively clunky Jeti/Spirit user interface. This video comparing YGE ESC integration with both VBCT/E and Neo/EVO compared with integration with Jeti/Spirit may give you an idea of what I a talking about: kzbin.info/www/bejne/sGjVm6hrlr51aa8 To me the real contest will be between Mikado radio/FBL vs. the upcoming Spirit WAVE radio/FBL

I have not published any videos over the past couple of months. I do plan to publish more videos. Let me know if you have any subject of interest.

Yes. I am still using the same transmitter case today, but I am currently using the dual transmitter foam insert (model number SPM6712) www.amainhobbies.com/spektrum-rc-dual-transmitter-foam-set-standup-spm6712/p244315 I used it for the VBC Touch and now for my VBC EVO and Jeti DS-12 radios.

@@johnahamelv thank you for your reply. I was thinking to put my VBC evo and 4 6s battery, do you think can squeeze in?

@@yeusing Assuming you are talking about 6S 5000mah packs, you should be able to fit the VBC EVO radio and 3 of those 6S 5000mah packs standing up. The 4th 6S 5000mah pack would have to lay sideways on either side of the transmitter.

I have a collection of gimbal stick ends. I do not remember where I purchased the ones I am using. I can tell you that the most common stick ends thread sizes are M3 and M4. Jeti uses M4. Other radios like Mikado VBar Control use M3 thread stick ends. So look for M4 thread size stick ends for this Jeti DS-12 radio.

Currently, the only function the newer VBC EVO can do that the older VBC Touch cannot is the ability to use an oscilloscope application which is only possible because of the VBC EVO's much faster processor. The VBC EVO's faster processor and larger memory capacity lends itself to other possibilities in the future.

Can you tell us more about this "Acc" parameter? Is there a downside to having it turned "ON"? Is there any reason to turn it "OFF"?

@@johnahamelv I suspect the downside is bigger current draw and marginally shorter servo lifespan

Each 100Ah mini size LiFePO4 battery I am using costs around $300.00 each, so $1,200.00 for all four batteries. Then you can add the cost of the charger(s) as well as the cost of wires and connectors. This LiFePO4 setup is certainly more costly initially compared to gas powered inverter generators.

No. LiPo batteries like we use in RC do not have an internal battery management system (BMS), and therefore cannot discharge themselves down to “storage charge” which is generally considered 3.85 volts per cell.

Thank you for getting back to me much appreciated

I have a video of what the battery does when I try to put it in storage mode is there anywhere I can send the video
