【High Quality & 10-year Life】ECO-WORTHY Lithium iron phosphate battery has the characteristics high energy density, stable performance and long life. LiFePO4 battery contains 4000+cycles. Each lithium battery can operate for more than 10 years, which is equivalent to 3 lead-acid batteries, and its weight is equivalent to 1/3 of that of lead-acid batteries. 【Safer & Smarter】The Lithium battery has a built-in BMS, all-round protection provided by the advanced BMS, prevents risk of over-charge, overcharging, deep discharge, overload, overheating and short circuit, and low self-discharge rate. In addition, it can be connected in parallel or in series to obtain greater capacity and voltage. 【10A Intelligent Digital Display & Intelligent Detection】It's not just a trickle charger, it's an advanced battery maintainer.When low voltage, vulcanization or loss of capacity is detected, the battery maintenance charger will directly prompt the user to repair and charge or the battery has lost value.
