Hi all
for BMS calibration purpose of my 48v 280Ah LiFePo4 DIY battery, I am asked by the BMS manufacturer to top charge and then discharge the battery down to 2.5v.
Yesterday, I successfully top charged (58.3v, with min cell was at 3,642v &max cell at 3,648v) with my inverter (EASun iGrid SV IV - similar to Voltronic InifiSolar V IV) then I drained the battery by charging my Tesla (still through the inverter).
-
Unfortunately, none of the battery bottom discharge stop points* were reached as my inverter shut downed before (while all cutoff/discharge/back to grid related settings were at the minimum).
Does anyone have an idea/solution that would allow me to continue discharging my battery after the inverter has shut down (what kind of easy to find and cheap 48v load can I use ??).
Thanks
Matthieu

- first cell to reach under voltage protection (2.5v)
- total battery reaching low voltage protection (43.3v).
