【Bluetooth APP Monitoring】 Compared with the traditional battery, PUPVWMHB 48V100AH lifepo4 battery battery adds Bluetooth connectivity to get various data (SOC) of the battery. After connecting with the battery through mobile APP, you can read the battery voltage, current, battery capacity and other important information at any time. Bluetooth connection range: no more than 5-10 meters from the battery. 【Born for Golf Carts】PUPVWMHB 48V 100AH Golf Cart LiFePO4 Battery uses A+level rate cells (Designed for 2C continuous discharge current), with cylindrical design. Compared to similar lithium batteries under the same operating conditions, it has better stress resistance and heat dissipation effects. Its overcurrent capacity and output current are 200% of that of 1C lithium batteries, with low internal resistance and the ability to achieve a high discharge current of 400A (5s), making it more powerful. 【higher Energy Density & 10 years Lifespan】PUPVWMHB 48V 100Ah LiFePO4 batteries adopt advanced Grade A LiFePO4 Cells. The compact body with higher energy density, lasting longer, more stable performance and superior efficiency. Its own built-in BMS to ensure the battery safety, 10 years lifespan and 4000-15000 cycles. 【Strict Protection & Speedy Charging】PUPVWMHB LiFePO4 battery has built-in 200A BMS to protect it from overcharge, over-discharge, over-current, high temp and short circuits. Operating Temp: Charge: 0°C~50°C; Discharge: -20°C~60°C. 【Warm Tips】 Our service team provide professional information and services, and respond quickly to solve problems in a timely manner.
