I'm building a small 230a 12v battery for a van setup using supposedly EVE cells (Docan) and a 200a JBD BMS. I don't have a power supply unit to top balance, and I don't have a capacity tester. I do have a basic multimeter. I don't plan on building any other batteries in the foreseeable future.
I'm debating whether or not it's worth it to spend $40 on a PSU to top balance and/or some more $ on a tool to capacity test. A Google didn't reveal anywhere near me (Portland, OR) that offers this type of service or rental of these tools.
I'm thinking about just building the battery and using it and keeping an eye on the BMS stats and the shunt (probably victron but TBD). This would make a dispute harder to succeed at with Docan but I think that would be an uphill battle anyway (maybe credit card company would step up). Am I a fool for skipping these steps?
