Unit Pack Power assemble ALL our batteries in our factory, Professional imported machine spot welding, neat electric welding, cleverly designed the routing direction. LiFePO4 Batteries live more than 2000 cycles at 100%/8000 cycles at 50% depth of discharge, without decreasing in performance. The average lifetime of lead-acid batteries is about two years(500 cycles) at just 50% discharge.
UPP Li-iron Batteries include Battery Management System (BMS) technology that protects your battery from Over Charger and Discharge, Over Current, Short Circuiting, as well as Low and High Temperature for increased performance and longer life. Compared to lead-acid batteries, lithium provides greater energy density and are at least 1/2 the mass, it is a perfect upgrade for any 48V Deep Cycle battery, and best choice for many applications such as Fish Finders, Ice Fishing, Camping, Solar System, Home Alarm Systems, E-Scooters and applications in Extreme TemperaturesDischarge Temperature -4? Please charge the battery with a dedicated LITHIUM BATTERY CHARGER, and no more than 4 batteries in series or parallel. Made from 100% safe, nontoxic, not hazardous energy, Weize 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 in any position.
