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 series-parallel to create higher capacity systems.

See “Battery Cabling and Hook-up Configurations” on page 57 for more information about battery inter-connection schemes.

Mixing Batteries Batteries connected in parallel should be of the same type and amp-hour rating and from the same manufacturer.

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.

Restrictions on Motor Size

An appliance may require three to six times its normal running
current in order to start. The Freedom SW 3524-230 can handle
surges to 6800 watts for five seconds, which translates to a locked-
rotor-amp rating of no more than 50 amps. The locked rotor amp	only.
may be specified on the motor nameplate as “LRA” or “LRI”.
When considering appliances with large motors, follow these
amps. The Freedom SW 230V may not be able to start a motor personnel
