48V 40ah Super Long Life Lithium LTO Battery 25,000 Cycles - 40 year service life - Battery for Life!

48v 40Ah New design with software BMS(RS232/485 and canbus communication)

Connect upto 4 units per system

The BMS allows for you to link upto 4 LTO powerwalls together for a larger capacity for your system.

40-Year Service Life

The LTO batteries have super long cycle life of 25,000 to 30,000 times, 100% DOD, equivalent to 40 years of service life.

Rapid Battery Charging and Discharging

LTO is the fastest charge/discharge lithium battery at 10C continuously, which can be fully charged/discharged in 6 minutes, to support critical loads such as air condition, water pumps, EV charging, etc. in residential, commercial, industrial ESS applications

Super good Low/High Temperature Performance at -50℃ ~60℃

Due to these low-temperature discharge characteristics, it is able to obtain up to 80% of its full capacity at a mere -30°C.

Integration with Energy Storage

Lithium Titanate Oxide (lithium titanium oxide) is bridging the gap between battery energy storage and the grid power.

10 Year Super Long Warranty

Amazing 10 year super long warranty period for LTO Solar batteries

Wide inverter compatibility

Bimble Solar batteries have been designed for communication and compatibility with the major inverter brands such as Victron, Huawei, Luxpower, MPS, Megarevo,Goodwe, Growatt, Voltronic, Kehua, Kstar, East, Luxpower, Megarevo, INVT, Ginlong, Sacolar, Sofar, etc.
