Lithium Battery Packs

BigBattery is your one-stop shop for all your lithium battery pack needs. We cover everything from home, RV, campers, and golf carts to industrial machinery. We’re proud to be the largest supplier of surplus and recertified batteries in the US. Our core purpose, here at BigBattery, is to promote the mass adoption of renewable energy solutions.

There are many reasons why lithium battery packs are in a class of their own. Li-ion batteries can be recharged hundreds of times without need for maintenance. They also tend to have a higher energy density and voltage capacity with a lower discharge rate than their competitors. This makes for better power and efficiency, as a single cell has longer charge retention than other battery types. BigBattery offers the best lithium-ion-powered batteries.
