The Aegis Battery 24V 40Ah Lithium Iron Phosphate - LiFePo4 Battery* is a state of the art rechargeable battery pack made with Lithium Iron Phosphate cells designed for 24V devices. It is perfect for e-scooters, e-bikes, solar applications, robots, and other applications that require a higher-energy density battery.

The battery comes with integrated SB50 (Discharging) and Anderson Powerpole (Charging) connectors making it a perfect drop in solution for your applications. The Aegis battery has a built in battery management system (BMS) that keeps the battery running at peak performance and protects the cells for thousands of cycles, including over-charge, over-discharge, over-current, and short-circuit protection.

If this connection does not meet your needs, you may also view alternative adapters here. 

For out of stock kits, we may be able to provide another compatible charger. Please contact us and we can check for you.
