Sterling Power Battery Chemistry Module


Multi Chemistry Multi Output charging device

The Battery Chemistry Module (BCM) is a retro fit device designed to be installed on the output of a current limiting multi output battery charger to allow the battery charger to have independent chemistry selection on each output. More and more so, individuals are having different battery styles/chemistry and different voltage scales (12V and/or 24V) all within their DC system. Due to this quagmire, the BCM is the solution to allow one battery charger to charge different battery chemistries at different voltage scales and at their correct charging profile. So, the BCM can essentially turn a very simple battery charger into a multi output, multi chemistry advanced battery charger with other inherent advantages.

Most cost effective method for multi chemistry multi output battery charging on the market.

Converts a single output charger into a multi output charger using multiple units.

Converts a multi output charger into a multi chemistry multi output charger.

4 Models:
12V – 12V
12V – 24V
24V- 24V

Battery temperature compensation and high battery temperature trip.

Do not install on a charger where the current exceeds the BCM’s rating.

Remote voltage compensation. To do away with voltage drop across long cables there is a feature which allows the charger
to compensate for a voltage drop up to about 1 volt.

Ideal set up would be a 12V AGM house bank and a 24V deep cycle bow thruster bank. From one charger you can charge both banks at their correct voltage scale and correct charging profile.

Simple to install. Simply connect the input of the BCM to an output of a current limiting battery charger and connect the output of the BCM to the battery bank.

Battery Chemistry Module or a Battery to Battery Charger?
We are frequently asked this question. For an in depth reason to choose the BCM over the Battery to Battery Charger. We recommend that you refer to our FAQ page. Here we shall discuss the main differences, essentially the benefits of current limiting in the versatility of the battery to battery charger. The BCM is a more cost effective method when connected to a battery charger.

A common problem that the BCM solves. Typically people have a mix of battery types in their system. A 12V AGM house bank and a flooded 24V bank for the bow thrusters. These batteries ideally want to be charged at different profiles. With a conventional charger this is not possible as you are fixed to 12V at an AGM setting. The BCM allows the user to charge at a flooded lead acid profile at 24V, while maintaining the charging profile for the starting battery at 12V. There are numerous combinations.
