• Quality Certification: The product has obtained high-quality testing certification. All products have passed strict quality standard testing before leaving the factory, including overcharge and impact testing, protection board testing, high and low temperature testing, capacity testing, vibration testing, short circuit testing and comprehensive charge-discharge aging tester, etc., to ensure. Safety and environmental protection: Class A batteries are made of lithium-ion environmentally friendly materials, built-in a 30A BMS protective plate,which not only have stable battery performance, but also have built-in overvoltage, overcurrent, overload, short circuit protection, and temperature protection. Safety Protection: The Battery equippes with BMS protective plate in battery. BMS is used to supervise battery by measure its voltage, temperature, current and SOC (State Of Charge), give out alarm under wrong circumstance, cut off electric power link in severe situation in order to protect battery and make its life longer. BMS can balance energy among batteries to make them more identical and expand its discharge cycle. (about 1000 cycles).
