Sure Power Battery Equalizer
Part#: 21100E00

24 volt to 12 volt , 100 Amp Equalizer

In dual battery (24V systems) it is often desirable to have 12V power available. Often this 12V power is available by tapping the battery stack at the junction of the lower and upper battery. Tapping the battery stack will result in unequal current draw from the lower and upper battery. Unequal current draw from the batteries will result in a state of charge unbalance. The lower battery will be discharged more than the upper battery. Eventually this will lead to damage and reduced life from the batteries.

The Sure Power Battery Equalizer provides an effective method for ensuring that the two batteries maintain voltage balance by providing all of the 12V current. The battery is only called upon to supply transient currents that exceed the output capability of the equalizer. The Sure Power Battery equalizer thus maximizes the life of the batteries in dual battery systems.
