12.8V 18Ah Deep Cycle LiFePO4 Lithium Battery by Powertech

Powertech 12.8V 18Ah Lithium Battery

Our customers have used this battery to run large fish finder units, as well as Haswing Transom Mount and Cassette Kayak Motors.

The Powertech 12.8V 18Ah Lithium Battery can provide continuous current up to 18A. It consists of regular 32650 LiFePO4 cells and an internal battery management system to ensure all cells are uniformly charged and discharged, as well as providing short circuit, over current, and reverse polarity protection. This provides you with a higher degree of protection than a traditional lead acid battery. The internal BMS will also limit discharge and manage cut-off voltage, to further protect the internal cells.
