Gens Ace Imars D300 Charger / Dual channel / Best quality RC LiPo charger ever!

[@michaelheliker2835]

Very helpful. Did not understand some of the options before this. Thanks!!

[@zanderflander7880]

Always balance charge multi cell lipos!! Not sometimes 😅

[@adam.gibson]

Does this have profiles like the old Hyperion or the Toolkit M6DAC? It is so convenient to be able to pre-set profiles so that you don't have to constantly change charge parameters when you have multiple battery types to charge. Just select the profile and go. I don't plan to have many smart batteries, but even if I did, I might want to charge them faster or slower. Profiles are so convenient.

[@alfieengler]

Did you find out if it does have profiles? Thanks

[@adam.gibson]

@@alfieengler unfortunately no. I didn’t find out.

[@Skynet5UK]

My SkyRC d100v2 dc input just crapped out. Bought this and the k2air to try out. The imars seems a much better build and interface so far.

[@Themlpg73]

What do you think about Hota S6 400W AC vs this Imars 300W AC?

[@NelsonsReview1]

That was super helpful. Thank you.

[@TF23DayRespawn]

This charger can't cycle nimh batteries? I have old batteries that need refreshing

[@ShenRC]

😁👍That's pretty slick of a charger right there brother!

[@RazorRC]

Honestly, this is going to be my go to recommendation for an all around quality charger.

[@davidzizelman2061]

@@RazorRC I just bought this charger. I’ve only owned the traxxas dual. I got some batteries that I used and 2 that I never used which are full. How exactly do I balance charge these? The full ones do I just discharge to 3.8v? They are 2/3s batteries 5200mah. Sorry for a newbie question.

[@adamantiumcards8931]

How does the storage mode work with g-tech? It’s asking me to confirm the balance?

[@JSmooVE3990]

Don't quote me cause I'm not sure but I think like the spektrum they discharge themselves.😊

[@LegendsPizzaCo]

Great review again. Would you choose thia over the hrtc t400 for charging 4s packs? I was debating between the 2. Gens Ace is about $30 more than T400. Thank you in advance.

[@RazorRC]

I’d buy this one. Much higher quality build.

[@LegendsPizzaCo]

@@RazorRC appreciate it. I went with the imars d300. It seemed like a well built machine with more power than the t400. The touch screen lured me in lol

[@rogerserafin]

Great video. Question: I just started racing 1/12th scale carpet on-road and the lipo pack we use in 13.5kv motor is 1s pack. Since the lipo back is 1s and doesn't require any balancing, how to I charge the lipo pack without getting the default screen that says " Balancer not detected" Press confirm. How do i bypass this and what button do I use to confirm it. I've tried all buttons to no avail. Any 411 is appreciated. Thanks Razor RC.

[@beenflying1]

Menu is the same as the HotA D6 Pro. Just missing some options the D6 pro has, like end charge percentage. :(

[@BASSstarlet]

Whats the key differences between this and the black "Gens Ace Imars Dual" that you reviewed 10 months a go?

[@RazorRC]

50% more power (150W/channel), auto smart battery detect.

[@DJCHURKLE]

Any idea what the balance current specs r? Can’t find on website

[@RazorRC]

I think it’s 1.2A

[@iam_schelle]

2:00 looks like 1.2a

[@DJCHURKLE]

Thanks fellas

[@GLiH222]

Can this charge batteries with a ID connector

[@forgetfulLlama31]

That's sweet. Want one! Thx for the vid

[@Pustul]

Can you check the internal resistance of the cells with this charger?

[@eyes2videos]

nice, but I am still missing howto update or if possible to see graphs on windows

[@ryanharris2415]

is it possible to still plug in a balance board to the charger versus having to plug the battery's balance connector straight in to the charger?

[@fuzzfreak1967]

Yes, I have this charger and plug in some balance boards from my old charger into it

[@MyKonaRC]

How would you charge a transmitter or receiver battery with a JR / JST end?

[@MyKonaRC]

I don't get why they didnt supply a DC input cable to power it by a 12v car battery, like the old Onyx 245 chargers.... That's a bummer, now I need to buy or make a cable that is XT60 to Alligator clip.

[@LyroLife]

What is the maximum possible Amp charge rate on a single channel for a 4s Lipo ? Only 6A like in the video??

[@TattuUAV]

Charge Current: 0.1-16A*2.

[@lautrique]

The USD cable can also be used to update the firmware.

[@coreymccartney3146]

Is anyone getting the error “High Voltage from the Balance Port”? I have been frequently getting this error on CHB, regardless of charge lead or battery used. Trying to charge or store 4800 2S LiPo packs.

[@RiverTheNerd]

Would I be able to charge batteries with QS8 connectors with this charger? Would I need to buy adapters/solder my own?

[@wolfysoto]

I'm new to rc world I do have k6 but learning alot since I got it only been days I like this charger I am getting genace 2× 5200mah 3s 100c I think this will be good for them

[@Spartanic89]

Can it charge two 6s 6000mah lipo battery at the same time?

[@RazorRC]

yes, at about 6amps each

[@gigi9467]

What would be better and why, this charger or the protek prodigy 625??

[@islandrc-duke1972]

cool charger and great overview

[@MrDaywalker1212]

I have been trying to find a charger thats decently priced to charge my Gens Ace 8,000Mah 3s lipo's and i recently found out my current charger cant go above 5,500Mah will this one do the 8,000? i cant find anywhere in the manual or the Gens ace website that states what level it can charge up too. Please let me know.

[@RazorRC]

you probably just need to increase the timeout or max capacity setting on your charger. but this will do 8000 mAh.

[@moravtchik]

Can I connect a standard battery with a JST-XH to the charger? Or do I need a balance board?

[@RazorRC]

You don’t have to use a balance board. I just use one because it gives more room.

[@moravtchik]

@@RazorRC Thanks. Does it mean I plug the JST-XH directly to the charger socket? It looks like it needs a bigger plug, maybe a 6pin. Maybe that's just for higher cell batteries. Or do you mean I don't need to connect the JST-XH at all?

[@gamedogrc]

waiting on my new 6s car. I think this will be my first charger. the rest of them look not so user friendly. Thanks For The Great Video.

[@squarebody4546]

Can this: - Show internal cell resistance? - Charge Nimh and Nicd? Thanks!

[@alfieengler]

Does this charger have a feature to save a battery profile? Like just select your battery and it saves the cell count, type, Amps, etc. my iCharger has this and so does the m6dac. Let me know pls!! Thank you!!

[@RazorRC]

No, that's the one feature this charger could use.

[@alfieengler]

@@RazorRC Thank you so much for taking the time to reply!! So, if I only use the gens ace 4s 6000 redline for example. I have to specify volts, and amps every time I use it? Or will it at least keep the last configuration?

[@RazorRC]

@@alfieengler it auto detects the voltage and keeps the last amp number used

[@alfieengler]

@@RazorRC good enough for me!! Thank you so much!

[@joshuajkoplin]

@@RazorRCI think it’s a marketing move by gens ace to push people into buying their smart batteries so they don’t have to deal with setting it up each charge and they save money not adding that feature. Could be for one of these reasons, or the other. My guess is both.

[@whoisjake5111]

Whoaa just recently I’ve been tryna look for a new charger! Just in time! Would you recommend this?

[@RazorRC]

Yes, I think this is going to be the best charger for about 90% of people out there. Does pretty much everything you need.

I got this charger. But i dont understand the diffrence in "Charge" and "balance" if you accely balance in charge, whats the point with balance then? Tanx for awsome video :)

[@RazorRC]

@@eiriknielsen3011 balance doesn’t charge the batteries, it just evens them out. You want to use charge.

[@eiriknielsen3011]

@@RazorRC Thank you very much

[@minekoiwa2971]

I bought one, I don't like it since there is no possibility of charging lipo batteries without connecting the balance plug. I have some batteries with active balance internal circuit. MY Toolkitrc M8 balances like shit, but it can do everything the D300 does.

[@masterjoe65]

thank you

[@proraptor4146]

You should always balance charge

[@backlashD]

The balance option still confuses me. Balance charging and storage also balance the cells. So what advantage does the extra balance have?

[@RazorRC]

I think it doesn't use any extra electricity. So let's say you have cells at 7.7, 7.7, 7.2 . It will just discharge from the first two and feed it into the 3rd until they're all even.

[@SpudicusMaximus]

The balance lead is used in basically every operation on all modern chargers. Every cell in a multi cell pack should always be at the same voltage. Without this balancing, the cells drift apart over time. It is impossible to make two battery cells operate exactly the same, especially over the lifetime of the cell. Now the problem occurs during charging, and if one of the cells is quite a bit higher on voltage than the others, it will just keep charging. This is a bad thing, the cells can only handle so much voltage. Then things start to get hot, swell, release the magic smoke, and possibly burn down your house. This is also a consideration during usage/de-charging. If a cell drifts too low, during use, it will just keep providing current. This results in an undervoltage scenario. Not as bad as overvoltage. But is a sure way to shorten the life of the battery, if not kill it outright. Typically during normal use (driving) the balance leads are not used, and thus each cell is not individually monitored. This is usually fine as the charger has already balanced the cells. Then it's ok to make the generalization that when the pack hits x voltage (depending on number of cells) during usage, it is considered empty.

[@TheParkingLotGarage]

@@SpudicusMaximus ​​⁠although I’m not the OP, I appreciate the detailed response! I’m still a bit confused about the difference between the “balance” charging as he mentioned at 8:45 vs actually selecting the balance option at 9:00? Is there two different meanings to ‘balance’?

[@SpudicusMaximus]

@@TheParkingLotGarage You'd have to consult your chargers manual for the specifics of it's function. For the Gens Ace D300 the 'balance' menu option will basically do an 'in place' balance. Though this depends on the settings used, as you can define the desired voltage in this mode. The charger will either bring all cells up to the voltage, or down to that voltage, or if it is current voltage it will just ensure all cells read the same value. Charging/discharging cells as needed. The charge mode performs balancing as well, though with the end goal of the battery pack being fully charged for it's stated chemistry.

[@TheChad435]

Can this charger discharge to 0v to safely dispose of Lipo batteries? I contacted GensAce for an answer and didn't receive a reply. :(

[@Krunkscooters]

Just put it in a bucket of salt water

[@jerryvolpini7987]

Damn, these things are tiny (I really do need to get over this 'bigger is better' mindset 🙄)! Appreciate the breakdown and could use a new race charger. I will definitely take a closer look. Any word on price, yet?

This is pretty similar to the D6 Pro, but it's much smaller and supports 150W/channel instead of the 100 of the D6 Pro. It also has the smart battery stuff too.
