The Aegis Battery Solar 12V 20Ah LiFePO4 Battery is a state of the art 12V 20Ah rechargeable battery pack with high power, excellent safety performance, low self-discharge rate, and lightweight. It is perfect for solar applications, such as remote surveillance cameras with solar power or solar powered control boxes. 

The battery box is IP65 Water-Resistant and comes with mounting brackets and sealed screw connections for your solar panel and device making it a great solution for remote installations where water resistance might be an issue for other batteries. 

Aegis Batteries have 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.
