	Batteries
No Maintenance	There is no need to add water and the tops of the batteries stay clean. Also the
	batteries can be used in any position and are Coast Guard approved for use
	without a battery box.
Low Self-Discharge	Unlike wet cell batteries, the gel cell will hold its charge for months if left sitting
Rate	with no load and no float charge. They can be stored in the off-season without a
	constant float charge and without fear of freezing.
Low Internal	The result of this is a higher battery voltage under load, which will result in better
Resistance	inverter performance on demanding high power loads. In addition this allows the
	gel cell to accept a high rate of charge, a plus for rapid recharging.
No Sulfation	The combination of acids in the gel cell prevents sulfation and eliminates the need
	for battery equalization.
	The result of these features is a battery that solves many common problems. Cycle
	life is high, even under constant deep discharging. For all these reasons the gel
	cell is highly recommended.

Battery Interconnection

In most cases, you will be using a bank of two or more batteries with your inverter/charger. You may connect batteries together in two configurations: series and parallel.

Series

Connecting two batteries in series will double the voltage of the battery bank. For instance, two 6-volt batteries connected in series will produce 12 volts; four in series will produce 24-volts. The amp hour capacity of the battery bank will be the same as each individual battery. As an example, two 6-volt, 220 amp-hour batteries in series will produce one 12-volt, 220 amp-hour battery bank.
