                                  BigBattery industrial lithium battery packs were designed as a plug-and-play option for electric commercial and industrial vehicles currently using lead-acid batteries. By switching to BigBattery lithium, your vehicle will gain more power and have less weight with increased operational hours. Your equipment will also have increased charging speed, zero maintenance, and no “cool down” period before recharging.

Our batteries power everything, including homes, RVs, campers, golf carts, forklifts, and other machinery. We’re proud to be the largest supplier of new cells 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. LiFePO4 batteries can be recharged hundreds of times without the 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 large lithium battery packs for sale online.
