LiFePO4 battery packs from PetaJoule: Energy en masse.

The difference between purchasing somewhere a bunch of single LiFePO4 cells and a battery pack from PetaJoule is our initial treatment. When you buy a 48V battery pack, you get 16 perfectly balanced and intially charged cells. We use special highamp equipment to be able to perform an intial charge when all these cells are connected in parallel.

This treatment will unleash the full capacity of these cells, as well as result in synchronization of their charge and discharge characteristics. We consider this the first crucial step in battery treatment and if your battery shop omits this step, you should demand better.
