To increase capacity and voltage, connect the batteries in series parallel
as shown in Figure 2.
EXAMPLE:
Battery = 6-volt (S6 L16-HC)
Battery Voltage = 6V each
Battery Capacity = 445 AH each
System Voltage = 12V System
Capacity = 890 AH total
EXAMPLE:
Twenty-four (24) 2-volt batteries at 2527 AH each = 2527 AH at 48 Volts
EXAMPLE:
Two (2) strings of eight (8) 6-volt batteries at 445 AH each
= 2 x 445 AH at 48 Volts = 890 AH at 48 Volts
EXAMPLE:
Three (3) strings of four (4) 12-volt batteries at 371 AH each
= 3 x 371 AH at 48 Volts = 1113 AH at 48 Volts

NOTE: Connecting more than three (3) series strings in parallel is not recommended. Multiple
parallel connections increase resistance between batteries and strings, causing an imbalance of
charge and discharge currents and may result in cell damage or premature failure which is not
covered under Rolls Battery manufacturer warranty.
