Just made my first LiFePo4 bank to replace old FLA. Its 48V. 16 500ah 3.2V LiFePo4. With the Ant BMS (that will did the video on). Outback Inverter charger and Outback flexmax
So all the batteries were pretty much the same voltage upon arrival 2.285-2.296 and together they were 52.6.
Connected batteries towards the end of the day and they started to charge and saw the voltage rise on the BMS lcd screen.
But wanted to give them a good charge for the first night so ran the generato1r for 3 hours which puts out 25-30 Amps. And BMS showed it charging.
It seamed stuck at 53.4 for with average of about 3.33 per sell.
The BMS shows 25amps coming in and the individual cell voltage seams to jump around a little bit in the 1/100s and 1/1000s of voltage (3.3XX)
But cant seam to get them past 53.5. It showed the battery status at 100% and AH 499.99
The BMS has the basic settings for LiFePo4. Number of batteries to 16 and battery size to 500.
So am i just paranoid that it should have charged more in 3 hours at 25amps? Seamed to hit that cieling and not pass it.
Or
Is the battery just really big? its 48V * 500amp so like 24 kW hours. And will take a lot more to get it charged up?
Tomorrow when the sun comes up i'll have more data and can post the BMS config.
