The self-discharge should be measured by adjusting the working point of the cell. Since LiFePO4 cells have a very flat characteristic curve over a wide range, the measurement is best carried out in a completely full or completely empty state. The self-discharge of the cell itself is also...

my main point are: 48V System for better efficiency and less cable cross section each block shall be moveable -> max 30kg per battery 30kg / Battery -> each cell about 2kg (2kgx16 = 32kg) Best cell fit for that is 105Ah (130mmx37mmx200mm) Then I searched for an enclosure and I found the...

I was looking for a good method to measure the discharge capacity of my Battery. First I started with a normal 24V/230V inverter with connected heater. This was not so greatful, becouse it was also very noisy and generates heat. So I decided to by an Solar panel inverter to do that. the...
