Parallel; Parallel Increase Amp-Hour Capacity - Heart Interface 10 Owner's Manual

Parallel

Parallel Parallel Parallel Parallel
Connecting two batteries in parallel will
double the Amp-hour rating of the battery bank,
while the voltage will be the same as each
individual battery. Example, two 12 volt 105
Amp-hour batteries in parallel will produce one
12 volt 210 Amp-hour battery bank.

drawing, the load is connected to the positive
terminal of the first battery and the negative
terminal of the last battery. This practice helps
to balance the battery bank and is called
cross-connecting the battery bank.

Amp-hours. The Amp-hour rating is based on
a 20-hour discharge rate, therefore, a 100
Amp-hour battery can deliver 5 Amps for 20
hours. If the discharge rate is greater than 5
Amps, the available Amp-hours are de-
creased. For example, if the load is increased
to 100 Amps, only about 45 Amp-hours will be
available at this rate of discharge.
