MillerTech lithium batteries are lightweight, non-toxic, and long lasting compared to traditional lead acid batteries. Each battery has a built in battery management system (BMS) which provides safety and proper charging/discharging. Each battery also features a built in state of charge (SoC) meter which allows you to conveniently check the voltage and remaining charge of the battery without a multimeter.

MillerTech PREMIUM lithium batteries are built with Grade A lithium iron phosphate (LiFePO4 or LFP) cells and are guaranteed for 5 years with a full repair/replace warranty. Each battery will last over 2,000 cycles at the most extreme use: its full discharge rate (1C or 45A) all the way to empty (100% depth of discharge). Or if you are a lighter user it will last well over 8,000 cycles at 40% depth of discharge.
