Explore this buying guide ↗Why consider this model?
- A shop or garage needing up to five separately controlled battery connections from one 120 V AC charger, where each battery fits a documented 6 V/12 V chemistry mode and the battery maker approves up to 4 A.
Tradeoffs to weigh
- This is a substantial off-board shop unit, not a compact one-car portable tender or an onboard charger. Its 4 A rating is per channel, but current varies during charging. The exact manual limits LiFePO₄ to 12 V and leaves the BMS condition unstated; its no-rain/no-snow instruction also rules out assuming outdoor use. 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.
