I’ve had a 100ah lifepo4 battery hanging around my boat for years , I use it to charge everything ! I’ve just checked it and it’s as new , must be 4/5 years old 😊😊😊

@petersimms4982 Nice :) the blue colored one on my workbench is at least 10 years old, let's just say it's been through some hard times :D

[@OFFGRID_Trucker]

Good stuff Dave..! I'm using Four Li Time 400Ah here..(1600Ah) it's alot of power. My panels (2 arrays) just don't get enough sun hours here with all the tall trees around here.. and can't cut them down either. I'm using an EG4 12k Hybrid for my AC and heat. It runs off a pair of 305w panels when the sun is out. Getting ready to relocate to AZ for lots of sun there.

[@solarpoweredge]

@OFFGRID_Trucker Thanks :D that's a nice setup. It's amazing what solar can do. Maybe I'll do a video about my house batteries some time. Never shown that. Exciting moving to AZ... apparently zero problems with sun... that will get the batteries charged up.

[@OFFGRID_Trucker]

@solarpoweredge yes.. I would like to see that video. Yeah.. full 10hrs of sun. The mini split starts working at 90 volts. I will add more panels to it when I get relocated and have the space to use them. Yes, the big move is exciting. 900 miles away. It's going to take four trips , almost 8000 miles. Lol

Good info, I really wonder if there is a tradeoff with the compact size. I’m a boater and the smaller size would let me put much more capacity in my limited area. I’m 79 so did I mention the much lighter weight would be great. So,, Can they and others mfg shrink all Lipo batteries

[@solarpoweredge]

@dc13032 Hi, the energy density on this battery is higher than past options (more power crammed into smaller space) It is 57 pounds, so lifting it is pretty challenging. Lipo or pouch cells in a hard case might be an interesting option! as long as they're covered by a protective shell

[@wallacegrommet9343]

@79gbell Yikes sorry about missing the discount, but I'm glad you got more batteries and hope they serve you well. My personal opinion is not to deep cycle LFP cells to 0% and be easy on them. If they last 5+ years, maybe that 25$ won't be so bad. I hope to get 5-10 years out of my batteries

[@schautamatic]

I still have to watch this but I did some snooping around. The one thing that stands out is the weight: 57 pounds. Usually, lithium batteries are considerably lighter than lead batteries of the same dimensions. But a 300AH lithium battery of that size has a lot of LiFePO4 crammed in it! Gotta wonder how safe this battery really is...

[@solarpoweredge]

@schautamatic They must have higher energy density, appear to be aluminum cases. I am doing long term cycling on it now, I believe it will be very safe. Have been cycling the 100ah versions and no problems whatsoever

[@Sailingengineer74]

Interesting battery, what kind of cellbalancer is inside? How long ""absorbtion time"" time at max charge voltage in order to allow for internal top balancing ? The cells will and do drift by time and DOD each time

[@solarpoweredge]

@Sailingengineer74 Hi! If you want to use OEM voltage set points, Wattycycle has published full charge parameters on their website in a PDF. Interestingly enough, I have run multiple banks of prismatic LiFePo4 cells for about 10 years with no balancing and no BMS. Those cells are still in service today. Once I have more exposure, I hope to do a video on that topic... including series cell dynamics, IR, the truth about C-rate, BMS vs. BPC, maximizing cycle life and so forth.

[@dougtheslug6435]

I think in any battery what they claim it will do is tell you the amount of cycles without any severe derogation, with any luck they'll last for twice that as they become less efficient as time goes on.

[@solarpoweredge]

@dougtheslug6435 Good point - my hope is to get 5-10 years or more cycle life from LFP by not abusing, overcharging or deep cycling. I truly hate running these batteries down to 0% for testing, but it has to be done....

[@7-z7y]

Looks like a good battery, but I have been looking into efficiency and 48v seems to run far more efficient than 12v systems

[@solarpoweredge]

Higher voltage can be more efficient at transmitting DC power. On the other hand 48v systems and inverters often cost more, and there are more cells in series and therefore increased chances of failure in that regard. Therefore, we can see engineering is about costs and tradeoffs. After over 10 years I tended to stick with 12v equipment as it is cheaper and more widely available, while using direct PV2L to drive larger loads such as heating etc. If cost was no object, I'd consider 48v, 72v, 96v or above to maximize efficiency :)

(box lined just to cut down on noise really). the house gets cold as i can not afford to heat it, so the heater is turned off. but again a simple dog bed warmer, maybe a battery blanket. only place that it would get that cold, is in the bed box. if it comes down to it the rv, and truck batteries can come inside the house for the winter, or just a very cold spell? temps through the end of this year will not get much below frost on everything. melts even before the sun hits it.

[@malk6277]

Hey, great video! If you were to put four of these in series for a 48v battery for solar, how would you go about wiring it and monitoring it, and what would be the options for getting it to communicate with an inverter like a Victron? Would it make sense to connect another BMS to the four batteries, and have that BMS communicate with the inverter?

[@solarpoweredge]

@malk6277 Thanks! Here is 100% my personal opinion.. if just starting out, I'd recommend using only 12v/parallel connections (join all positive and negative battery terminals). Monitoring using a basic coloumb counting battery meter they are about 80 bucks. Add a good quality 12v inverter with a fuse. No extra BMS needed, it is internal to the batteries. There is no way for these batteries to communicate with an inverter, BUT they will power an inverter just fine! Hope this helps - Dave

[@malk6277]

@@solarpoweredge Thanks Dave, much appreciated. I need to build a 48v battery, for our home. I'll keep researching.

[@solarpoweredge]

@malk6277 Welcome sir :) sharing a bit of my experience: if you do put normal 12v LFP batteries in series, I recommend checking each 12v unit with a quality voltmeter at least once per month. If one of the 12v units drops or raises it's voltage more than a little compared to the rest, I recommend to stop using the system immediately and manually re-balance each 12v battery. Use the greatest care and caution! The 4 individual "BMS" circuits are often not able to solve this type of issue at all, and it can cause a serious "problem" if not caught. Best option (but not really cheap) is to use native 48-volt batteries. It is not my intent to discourage solar DIY'ers, only share truth, knowledge and prior experience :)

More information than I really need to know. Bottom line: if I lost power which electric heater will run longest on this battery to keep me warm?

[@CriticalThinker-42]

WattCycle Claims they use EVE A Rated Cells in these Batteries. According to a video on the EVE 280 and 300 Ah Cells, Both Cells are the Same Size, and EVE under rates their Cells by 10% so their 300Ah Rated Cells will Actually Flow ~330Ah, and their 280Ah Cells ~311Ah (Max) before the BMS cuts them off. Remember that Battery Manufacturers usually stick to standard size Cases for their common rated batteries for same form factor mounting, and that LiFePO4's Cells are Smaller than Lead Acid cells. ALSO Overseas Shipping Charges are mostly based upon Volume, and smaller Dimensions per unit allows for less shipping cost per unit from China. (NOT Shipping as much Air!) *** APPARENTLY... WattCycle is taking advantage of this and are using EVE's 280Ah cells to be able to Claim/Give 300Ah Capacity while selling them at a lower price, and allow for a Smaller Void to be left within the Battery case allowing the MINI's smaller size.

Your findings were similar to Wil Prowse as he tested the 100 AH model. Watt cycle seems to be the lowest priced LiFePO4 battery out there. I heard there is an abundance of lithium hence battery prices are dropping.

[@solarpoweredge]

@philc.9280 Hi, you are right... there has been too much mining of lithium (over production) and it sometimes costs more to mine it than what they can sell it for. It's good to have lower prices, but at the same time we certainly don't want the market to collapse leading to production problems and a battery shortage. PS I reviewed a the WattCycle 100ah units also, and they seemed to be pretty good batteries. They are in long-term testing right now in my shop. If things go well, I will be able to do long term updates on all the batteries I have reviewed after 1 year or so.

[@yanseiner1418]

The specs claim a low voltage cutoff of 9.2V. That seems crazy low; well under the 10.2V hard threshhold for cell damage. I have yet to see any explanation for how they achieve this. My cynical self says they're trading longevity for greater stated capacity, claiming more capacity at the risk of damaging the battery. I'd love an explanation of how they achieve this.

[@solarpoweredge]

The sample I received yielded >=300ah at 11 volts. My personal philosophy on LFP is even 10.2v is too low and the "BMS" should be a last line of defense. No one competent and knowledgeable about Lifepo4 chemistry would regularly discharge 4S LFP to 10v, let alone 9v unless they were in research/testing, an emergency or made a mistake. Yet I'm sure it happens all the time. That said, 10.2v beats 9.2v, which in turn beats -0.0v and would prevent a total loss. The only time I bring LFP down to 11 volts is for a review, would never treat my LFP cells that way voluntarily. After over 10 years of using Lifepo4 as an early adopter, I want to do a video on the "truth" about how these cells should be treated. There is so much misinformation.

[@yanseiner1418]

@@solarpoweredge I guess I should get something like the Victron Battery Protect to cut off the loads and leave the chargers connected.

[@solarpoweredge]

That should work... or even a DIY programmable switch connected to DC contactor. Too low/high, the whole system shuts off instantly. I have never used a BMS on my main house banks. Just raw cells that are well balanced and properly charged. But, protecting them with a low voltage cutout LVC is an absolute must - otherwise could wipe out the whole system if accidentally running them down too low while unattended. (HVC is a good idea too)

I was considering several 400-600 AH Lifepo4 Brand of batteries, but most had single 200-250 amp BMS limitations. It would run a 3 KW inverter, but I like the idea of having the potential of 400 amps total if there are other loads besides the inverter. However I would need to add a couple of 4/0 jumpers to complete the setup in my RV. Currently there is a pre-molded battery tray for 2 group 27 batteries, these almost would fit! The LiTime 560 AH battery does not fit that space. Currently we are planning to be on the road headed to FL when AMZ would be able to ship these to my son where we are visiting now. Maybe checking for a Black Friday special is in order. Cheers, David - KU9L

@KU9L Hi, I cannot see the RV layout, just sharing my thoughts... maybe you can modify the battery tray or add a second battery compartment. it can be difficult to find batteries when there are space constraints. It's an engineering challenge... hope you're able to find the right ones. One option I have leaned on in the past is long 4/0 cables and add an extra battery any where it can be hidden. Or just hide one right next to the inverter. It will share some amps and reduce the load on the batteries closest to the inverter. Of course this kind of thing is a bit stressful if one has OCD :)
