Overview
The SkyRC T400Q is an AC/DC 4-port balance charger/discharger designed for RC battery charging across multiple chemistries. It uses four independent circuits that can work simultaneously, delivering up to 100W and 12A per port (total charging power: 400W). It supports LiPo/LiHV/LiFe/LiIon 1-6S, NiMH/NiCd 1-15S, and Pb (lead-acid) 2-20V, with universal-voltage AC input (100-240V) and DC input (11-18V).
Key Features
- Quad-port charging with four independent circuits for simultaneous charging/discharging.
- Power per circuit: up to 100W and 12A; total charging power: 400W.
