Ultimatron 12.8V 300Ah LiFePO4 Lithium Battery with BMS Smart Bluetooth

LiFePO4 lithium battery is definitely the best alternative to 12V lead batteries because they have a stable supply voltage even under heavy load. Offering the advantages of lithium: light weight, stable voltage, high number of cycles. It can directly store more than 96% of the energy supplied. High performance even in extreme conditions. Deep and constant discharge and refill efficiency.
Furthermore, thanks to the BMS (Battery Management System) Smart integrated with Bluetooth 4.0 connection, it is possible to monitor the values in real time and the status of the battery directly from your smartphone thanks to the convenient dedicated App, for smartphone or tablet.
The fields of application of lithium batteries are diverse, especially for stationary or mobile use. In particular, mobile homes, solar boats, electric boats, electric scooters, golf cars or even electromobiles / wheelchairs and cleaning machines are increasingly equipped.
Series and parallel connection for 12V, 24V, 36V, 48V applications.
