What's in a title?
Sorry I'm in to many threads, forgot you shared a photo. A shunt would be a good idea to track usage and know actual capacity.A shunt? I have what's in the photo.
How many watts is the water heater?Yes but they didn't run for that long, the coffee machine maybe 5 mins *2 and the water heater for max 30 mins, that shouldn't even make a dent in 48v * 100ah
Yes, you need to get them around 3.5V / cell.So they should be charged to 14.6v, I had them charging from the 15amp charger I bought pretty much for the last 2 days. And the max they would take was 13.4, do I need to leave them charging till they get to that amount?
What charger are you using?
It's entirely possible the cells within the packs are out of balance. You're positive the BMS for your batteries doesn't have bluetooth?
