Can I parallel my B-TEC/eLITE Battery?

Enerdrive supports the paralleling of up to 4 B-TEC G2/eLITE batteries that have the same capacity and voltage (e.g. 2 x 125Ah 12v B-TEC batteries). The batteries being connected in parallel should also be no more than 12 months apart in age and no more than 300 cycles apart in usage. This ensures that all the batteries in the bank will perform at the same potential.

During installation, the following steps should be taken:

1. Each battery should be fully charged separately and left for 30 minutes to rest. Prior to connecting them, the voltage of the individual batteries should be checked to ensure that there is no more than 0.2V difference between them. This ensures that batteries are balanced at the start.

2. Parallel cables between the batteries should be equal in length and at least the size of the main battery cables, though larger is better. Please refer to the user manual for more information regarding minimum cable size and check out our cable FAQ here.

3. The main battery cables must be connected across the entire battery bank (i.e. positive to first battery in the bank and negative to the last battery in the bank).

Once installed, the following steps should be taken:

1. The state of charge for the individual batteries should be checked regularly (keep in mind that the Enerdrive App can only display one battery at a time). If the state of charge has drifted apart more than 5%, the batteries should be separated and charged fully before reconnecting.

2. The batteries should be separated and charged back to full at regular service intervals.

3. Maximum discharge limits of single battery should still be followed (e.g. Parallel 125Ah B-TEC batteries still have a maximum of discharge current of 100A).

4. It is recommended than an external battery monitor (e.g. an ePRO Plus) be fitted to the system so that the total system state of charge can be easily monitored and the batteries can be prevented from reaching their cut-out point.
