Q: how is your lifepo4 100ah battery 22lbs while other batteries are 30lbs am i getting less capacity a: lifepo4 is a type of dry-cell battery unlike sealed lead acid batteries whose capacity is rated by the amount of liquid electrolyte surrounding the electrodes. The weight difference doesn t come from chemicals or the electrode metals inside a cell as they are lightweight lithium and graphite but from the metal materials used to manufacture the cell cases. Our 100ah battery consists of 8-piece 3.2V 50a cells compared to 20-piece 3.2V 20a cells or 40-piece 3.2V 10a cells in other leading manufacturer s batteries. The carefully crafted design reduces total weight down to an incredible 22lbs while providing a clever increase to voltage stability.
