Model QPA12v/50A is designed with maximum flexibility. The adjustable current control means it can charge groups of wet cells, AGM's or gel batteries requiring as little as 1 amp each, or put as much as 50 amps into one battery. The adjustable voltage control means you can control final voltage with precision. Equipped with ammeter, and digital voltmeter for battery monitoring. Safety features include, reverse polarity protection, and current limiting.

Designed around the needs of the battery specialist, fleet operators, warehouses, and reclaimers. The constant current output is current limited, and is controlled by one linear adjustment. Voltage is adjusted automatically on the QPA6-127v/6A, and a range switch is used on the other two models. These models use no micro processor, and are ideal for busting loose stubborn sulfation using a slow 12-24 hour charge. The reverse polarity feature, and isolated, all copper transformer make the Series Multi's safe.

Parallel Cable Set: Charging batteries in parallel means connecting all the positives, and all the negatives together. This cable set does just that. The ends are then connected to the charger cables.
