I'm a newb trying to build a DIY pack. It has a JBD BMS, 4 304AH EVE cells and a Progressive Dynamics 60A charger. When I installed the app, it asked for capacity and I gave it 1216. Then when I go to charge it, the app says its charge load is 59.xA and then it starts dropping rapidly to like 5A.
I thought since the Nominal Capacity was wrong in the PARAMS SETTING, maybe the low and inaccurate capacity is telling the charger the battery is almost full so it stops taking so much energy. So I re-set (again) the Nominal Capacity, tapped save in the PARAMS SETTING and the Nominal Capacity defaults to 560AH no matter what I do. The pack measures 14.36V.
1. How can I set the correct Nominal Capacity for the BMS?
2. How could I fully charge the battery with the BMS and Progressive Dynamics charger?
