I’m working on my first build and have run into a roadblock with batteries. I have a degree in applied physics and feel very confident that I could build a battery from individual cells, however as I look through cells that cost anywhere from $3-8/cell, and do the math of a 12s12p or 14s14p battery, plus a BMS that’s capable of handling the amperage required, I find myself running into a coupe of questions like:
- How much does a battery typically cost people?
- Are people really spending close to $1,000 for a battery?
- Are there suppliers that people are getting them from that are simpler/cheaper than building one yourself?
- Do you need a BMS for discharging the battery, or only for charging it?
Anyone able to answer some/all of those questions from their own experience?
