Hi, I’m in the middle of a build,
using HCX-D223 10S-80A BMS I didn’t connect balance wires yet… I’m trying to use it to charge the battery and as an e-switch only for now.
during charging, it’s main heat sink is getting very hot (about 70-80 degrees Celsius) - is this normal?
it’s e-switch is on, but output gives me some weird voltage, 28ish volts and falling as I’m measuring, as if I’m measuring a small capacitor. battery voltage is in the normal range, 38-ish volts
I’d expect balance wires to become relevant when battery is fully charged, but is the whole device behaving weird because balance wires are not connected?
