Unleash the Power of the Future - Weize 48V 100Ah LiFePO4 Battery with a 10-Year Warranty!

BUILT TO LAST: Our 48V 100Ah LiFePO4 Batteries are designed to exceed 2000 cycles at 100% depth of discharge or 8000 cycles at 50% depth of discharge (suggested), without any decrease in performance. In comparison, lead-acid batteries typically last about two years (500 cycles) at just 50% discharge. This means a LiFePO4 battery will last you 10 times longer than a lead-acid battery, ultimately reducing overall cost. Additionally, our battery includes cold weather protection, which is critical for maintaining performance in challenging conditions.

AUTOMATIC 100A BMS AND MAINTENANCE-FREE: The built-in Battery Management System (BMS) protects your battery from Over Charge and Discharge, Over Current, Short Circuiting, as well as Low and High Temperature for increased performance and longer life. The BMS will automatically cut off the battery and the voltage will drop below 1V. Only when the circuit is cut off, the battery will automatically reactivate after 1 second (No longer need a higher voltage input to activate).

LIGHTWEIGHT AND VERSATILE: Compared to lead-acid batteries, lithium batteries provide greater energy density and are only 1/3 the weight of lead-acid batteries. This makes them a perfect upgrade for any Deep Cycle battery and the best choice for many applications such as Fish Finders, Ice Fishing, Boating Electronics, Camping, Solar System, Home Alarm Systems. Please charge the battery with a dedicated LITHIUM BATTERY CHARGER, do not connect in series and no more than 10 batteries in parallel.

SAFE AND ENVIRONMENTALLY FRIENDLY: Made from 100% safe, non-toxic, and non-hazardous materials, our LiFePO4 battery has higher chemical stability. It is not prone to thermal runaway and will not overheat or catch on fire even if punctured. With no acid in the battery, you're able to safely mount it in any position. However, please read the user manual carefully before using and don't hesitate to call us if you have any questions about the battery.

Harley-Davidson battery

My original Harley battery was struggling to turn the high compression bike over with only 340 cold cranking amps, I put this lightweight 600 cold cranking amps battery in and wow could not believe how quickly it spun the bike over. Very happy. Just ordered another one for one of my other bikes.
