Battery Banks
As your power requirements increase, you may need to use more than one battery to obtain sufficient capacity. Batteries can be connected in parallel, in series, or in
See “Battery Cabling and
Mixing Batteries Batteries connected in parallel should be of the same type and
It is not recommended to connect batteries of different types, amp- hour ratings or manufacturers. Improper charging and decreased battery life will result.
Battery Bank Sizing Worksheet
The following worksheet is a guide to help you determine your battery needs. Be generous in estimating the time for which you will run each of the loads to ensure sufficient battery capacity.

• Make sure that the motor’s LRA rating is no more than 50 |
