A lead acid battery can be charged down to about 50% of its capacity before it needs to be recharged. This is referred to as “Depth of Discharge” So, a typical 200Amp hour lead acid battery bank contains 100 usable Amp Hours.

A 200 Amp Hour Lead Acid Battery bank weighs around 50Kg, which is quite heavy compared to the latest in Lithium.

Lithium Batteries:

The Btec range also comes with an internal Battery Management System or BMS. The BMS will monitor each cell within the battery and is designed to protect the battery from over charge, over discharge, over temperature and short circuit.

Due to the internal BMS, the Lithium Batteries are unable to be connected in Parallel to increase overall capacity.
