    The project assembly it’s beyond perfect, as i said in the video before, it’s too expensive for 25 amp/hours, I would rather keep it simple and stupid assembly to get the same rate of volts and amps/hours in the case of DIY otherwise just buying a battery already in the market and the capacity will be 20 times more

    love these kind of board, started a power wall with it, work great, but it seems that lifepo are becoming cheaper than doing this with llion … what do you think? lifepo is the way to go these day?

    It seems there's a 5 unit minimum on the link as I already have the 5 battery boards….. glitch or ?

    Am I missing something? If it can only pass 25 amps, the way that's built, why have two 100 amp BMSs? Why have 100 amps, for that matter? Without providing redundancy it would take four of those stacks to reach 100 amps, by what you're saying?

    Seems expensive compared to gas, why would one spend all that $$ to make a battery? When you can buy a premade 100 amp lifepo4 from Amazon for under $400.00 usd complete.

    That doesn't make sense, unless your that type of nerd who likes to tinker with electronics.

    Imo, having a higher output bms with higher quality parts/ batteries and allows me to build let's say a 10,000 amp battery in a compact size would be the only time I would consider building a custom battery.

    Something that is not on the market or is and it's cheaper to diy it.

    Overall good info in this video.

    Is there a diy solution for a marine application ? Would this pass a marine survey ?

    What could I use this battery module for?
