Active battery cell balancing is NOW here

We are the only supplier of the Active BMS. We do not sell the passive type. This is like adding 30% to 50% more batteries in efficiency.  The cycle times will also increase greatly.

Let us install all of your wiring for you.  Enjoy our warranty of excellence.

We also provide a volt meter, or fuel gauge as some call it.  An expensive monitor is not needed when using the Active type because it balances and keeps the cells maximised for you.

This can only be accomplished  with an electric motor.

All battery chargers are based on cell count and the amps or speed of the charge.

Example: A 5 amp is the slowest but light enough to carry on board. Over 20 amps could shorten the cycle times.

We can quote the end user price for a set or any size you choose.
