A wall-mountable, 120 V AC fleet/shop charger with ten independently configurable 4 A battery channels. Each bank has separate voltage and chemistry controls; the exact manual supports 6 V lead-acid and 12 V lead-acid or LiFePO₄, not 6 V lithium.

Explore this buying guide ↗Why consider this model?
- A fleet, rental, repair-shop or collection setting needing up to ten separately controlled battery connections from one 120 V AC unit, where each battery fits a documented 6 V/12 V chemistry mode and the battery maker approves up to 4 A.
Tradeoffs to weigh
- Its ten output paths and 13 lb, 19-inch chassis are intended for a dedicated shop or fleet location, not a compact single-car kit. Each bank is rated up to 4 A independently rather than sharing a single 4 A supply, but charging current varies by battery and stage. The exact manual limits LiFePO₄ to 12 V, leaves the BMS condition unstated, and says not to expose the unit to rain or snow. Check the exact manual revision because older third-party search text suggested a lower historical output for the same base part numbers, but that file could not be verified.
