I recently bought some 12V lithium ion batteries off of Aliexpress. I probably should''ve paid more attention to the item description as I realised that the pack has internal circuitry which limits the discharge current to 4.8A and also protects the battery from short circuits. I need it to be capable for "short" (10 second) pulses of 30A.
Capacity loss during pulse discharge of batteries Most battery discharge curves show constant-current or constant-power discharge. Batteries that have a significant Peukart effect exhibit lower capacity at higher discharge currents. Most primary cells, and lead acid secondary cells show significant Peukart effect.
