Home Energy Storage Powerwall Battery 51.2V 14Kw to 15Kwh Lifepo4 Battery (220v 5kw inverter optional)

 

This home energy storage battery uses A-rated lifepo4 batteries with higher energy density, boasts over 6,000 cycles at 80% DOD for longer cycle life, faster charging, and more safety.

LED control panel

Battery control panel consists of LED display and touch buttons, which can control the operation status of the battery, the communication match between the battery and other devices, when need to check the internal parameters of the battery and the overall operation status of the battery can be queried through it, when the battery has a malfunction will also be shown directly on the LED display.

Battery structure

This battery with BMS is the battery system independently developed and designed by Keheng, so the internal battery structure is more stable, the alignment is regular and seamless, which can greatly reduce the safety problems such as short circuit, broken circuit, heat generation and other safety problems during the use of the battery, so that you can use it with more peace of mind. It also comes with 2 sets of 1 pulley set, which can reduce the resistance encountered by the battery in the process of moving, making it easier to move.

Battery casing

Li-ion battery case, use high-precision alloy materials and is plated with protective film and white paint, which can, to a certain extent protect the battery from magnetic field; the battery case is lighter in weight, has greater drop strength, and can reach IP65 protection level, in the process of placing for a long time can be done to protect from interference with charged dust, so that the battery’s service life is more long!

Suitable size, light weight, more convenient to use, the bottom of the battery is equipped with pulleys, faster movement, and more customization options!

51.2V 15KwhPulley Lithium Iron Phosphate Battery with BMS can well meet the home power supply needs including: daily electricity (air conditioner, TV, refrigerator, lights, stove, stereo, computer, water heater), outdoor stalls, camping in the wild, and so on.
