The Aegis Battery 12V 12Ah Lithium Iron Phosphate - LiFePo4 Battery is a state of the art rechargeable battery pack made with Lithium Iron Phosphate cells designed for 12V and 24V devices (run in series). It is perfect for mobility scooters owners that want longer life, more range and faster charging for their mobility scooter battery.

This mobility scooter battery upgrade kit includes: 

  • (x2) 12V 12Ah LiFePO4 Batteries (288Wh Total)
  • (x1) 24V 5A LiFePO4 Charger
  • (x1) Male 3-Prong XLR Adapter
  • (x1) Battery Voltmeter

Mobility Kit - Installation Guide

Most mobility scooter applications use two of the 12V 12Ah LiFePO4 Batteries connected in series to output 24V.  For Lithium Batteries you will need to use a new lithium 24V 5A Charger and a Male 3-prong XLR adapter to be able to plug the charger directly into the scooter's charging port. 

While it should be a simple drop in replacement, please consult your mobility scooter manual and manufacturer before upgrading to lithium batteries to ensure safety and compatibility.

The battery comes with integrated  F2 Type Terminals, making it a perfect drop in replacement solution compared to your old lead acid batteries. The Aegis lithium 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.
