Delong Energy’s 4.28kwh 48V 100Ah lithium ion battery comprises 15 3.2v lithium iron phosphate(lifepo4) cells connected in series. The built-in BMS developed by a professional team can protect the battery from overcharge, over-discharge, over-current, high and low temperatures, and short circuits.

The 48V 100Ah lifepo4 battery pack can match most mainstream inverters, such as Deye and Growatt. The A-grade cells and battery management system allow the battery to have more than 6,500 cycles and a service life of up to 12 years.

The 48V 100Ah lifepo4 battery pack is wall-mounted. It is small in size and light in weight. It does not take up too much home space and is a reliable household energy source. Wall-mounted batteries are easy to install and require little to no maintenance. The LCD shows the working status of the battery in real-time for easy management.

We provide multiple international certifications such as CE/UN38.3/MSDS for a 48V 100ah lifepo4 battery pack. In addition, there is a 10-year warranty, providing professional after-sales service and technical support.

Our products support parallel use if you want to expand the battery capacity.
