Berger & Schröter 4R25 LiFePO4 Rechargeable Battery 6V 7.5Ah

This 4R25 LiFePO4 rechargeable battery delivers a stable 6V output with a 7.5Ah capacity, making it a reliable power source for lanterns, camping lights, warning lights, and security systems. Its integrated BMS protects against overcharge, over-discharge, overcurrent, short circuit, and temperature extremes, ensuring safe operation across a wide temperature range from -20°C to 60°C.

Advantages

LiFePO4 chemistry provides over 2000 cycles at 80% depth of discharge, significantly outlasting traditional batteries. Low self-discharge of less than 3% per month means the battery retains charge during storage. The robust ABS housing and spring contacts ensure durability and easy installation in compatible devices.
