Deltran's Battery Tender 10-Bank Shop Charger 021-0134-DL-WH is an advanced SuperSmart Battery Tender® Battery Management System that is light years ahead of any standard battery charger.

It's the first fully automatic, constant-current battery charger designed to charge and/ or maintain up to 10 12-volt or 6-volt batteries simultaneously @ 4 amps. Designed for 12v Six-cell and 6v three-cell Flooded/AGM/GEL Lead-Acid Batteries and 12v Four-Cell Lithium Iron Phosphate (LiFePO4) Batteries.

The Battery Tender® charger from Deltran has a “SELECT” button for each channel which allows you to switch between charging a 12-volt Standard/AGM Lead-acid or 12-volt Lithium Iron Phosphate (LiFePO4) battery or a 6-volt Standard/AGM Lead-acid battery.

Note: For Lithium chemistry compatibility, this smart charger will only charge 12-volt rated Lithium Iron Phosphate (LiFePO4) batteries.
