    Is this cell voltage difference bad?

    Hey everyone, I finally got my Overkill BMS working right and charging, but notice this voltage difference between cells. Is this acceptable or should I top balance them again? The cells are Fortune 100 ah cells. Also I don't actively use the pack, will it lose capacity permanently over time if...

    Top Balance Charger?

    Hello, I was wondering if anyone suggested a charger for top balancing my Fortune 100 Ah cells? I have a nice 4/15 Amp Victron for 12V and a bench power supply for electronics projects, I tried the Victron and realized it won't go below 12V. I tried the bench psu and set it for 4 Amps, it never...

    Will Solar Panels Be Damaged If Unplugged?

    Hey everyone, I was curious, if I get around installing solar panels on my property, will they get damaged if I don't have them connected to anything? I ask because I may set up my 5 panels in the coming month, but I may take a few weeks after to connect them to a charge controller, batteries...

    If I Charge Via AC, Should I Leave LiFePO4s On A Charger?

    Hey everyone, I plan on making a 24 V Hand Truck system for backup power if our grid power goes out. I will eventually put a charge controller on it too to hook up to our panels. Anyway, I was wonder if it's good practice or safe to keep my LiFePO4 cells on an AC charge to keep them topped off...

    4000 watt Inverter on 12 V?

    Hey everyone, I know it's preferred to have anything over 2000 watts on a 24 v or 48 v system. I plan on building a 200 Ah battery pack using Fortune cells and was going to use a 4000 Watt inverter with it. Is there anything I need to look out for, like do I need large gauge wires, a special...

    Fortune 100 Ah or 280 Ah Aliexpress (Will suggested)?

    Hey everyone, I kind of have a dilemma. I was about to buy 100 Ah Fortune cells to make a 100 Ah pack, but for not much more I could get 280 Ah cells from an Aliexpress buyer with a US warehouse. I know, at least based on what Will has stated numerous times, that the Fortune are high quality and...

    Mixing Batteries? Manufacturers?

    Hello how safe or unsafe is it to mix batteries by manufacturer? I was thinking of buying SOKs, but I may want to build my own packs with Fortune cells too later, I haven't decide. I just heard it could be bad to mix cell makes/models. Is that only because of the health of cells?

    Growatt or MPPT for 24v?

    Hello, I'm going to build my own 24v system on a hand truck with an electrodacus and 8 100 ah Fortune cells, but I was wondering if you suggest the Growatt or the MPPT all-in-one and why? It seemed to me that Will upgraded to the Growatt for his 48v setup, but I didn't know if it's an upgrade on...

    Why did Will go with Electrodacus?

    Hey everyone, does anyone know why Will went with a very cool Electrodacus SBMS for his 24v handtruck system? I'm confused because it's limited in output current compared to something like Overkill Solar. Maybe I don't fully understand what it is and does, or how it's setup.

    EMP/CME Battery Choice

    Hey everyone, I was wondering if any of you have taken into account EMP and or CME protection? I've done a decent bit of study on the subject, my conclusion is that LiFePO4 batteries are great, but their largest weakness is the BMS. So I had to rule out Battle Born batteries sadly since they...

    Overkill Solar or Electrodacus SBMS for 12v 4s?

    Hey everyone, I was curious what you would suggest for as 12v system I plan on building soon. I'm going to make it like Will's hand truck generator setup, but 12v for now. I will use it to power my home office in case of emergencies. But I am confused as to why Will used the Electrodacus instead...

    SOK or Battle Born?

    OK, I know in some ways this is like comparing Apples with Apple Pie, but I am seriously not sure which battery to go with between SOK and Battle Born. Yes, I know I can build a battery for cheaper, but I don't care to find Grade A that from a reputable buy, wait weeks if not months for it to...

    Should I Make My Own or Buy Pre-Made?

    Hey everyone, I've built 10 Ah LiFePO4 battery pack with BMS previously. I was thinking of either building or buying a 100 Ah battery. I was wondering if you suggest building it myself or buying a pre-made one? I was going to build my own, but started looking at prices for the components...
