Sure Power Battery Equalizer 

24 Volt to 12 Volt | 30 Amp Battery Equalizer | Fixed Output

The Sure Power (EATON) battery equalizer maintains the balance of a 24V series battery pack, allowing large 12V loads to be powered from the 12V center tap and providing 30A of output current to maintain battery balance. The 21030E10 battery equalizer allows the inrush current of 12V loads to be supported by the batteries while maintaining system balance. The 21030E10 reduces overall system cost and improves system reliability.

This converter does NOT come with it's matching Deutsch Connector, and must be purchased separately.
