SKYRC iMAX B6AC V2 AC/DC Dual Power LiPo Battery Balance Charger/Discharger Review (2026)

Who it is for

The B6AC V2 is aimed at RC and FPV hobbyists who want a trustworthy, well documented balance charger for a mixed fleet of battery chemistries rather than a single purpose LiPo charger. Because it runs from either AC household power or a 11 to 18V DC source such as a car battery, it works both as a home bench charger and as a field unit when paired with a 12V supply. Buying the genuine SKYRC version rather than one of the many clone B6 chargers on the market matters here, since the authentic unit uses SKYRC's own charging profiles and firmware rather than a copy of varying quality.

Charging and discharging

Charge current adjusts from 0.1A up to 6A, with a maximum charge power of 50W, while discharge current ranges from 0.1A to 2A at up to 5W, figures confirmed in SKYRC's own instruction manual. Those numbers put it solidly in line with other single channel B6 style chargers rather than the newer 200W plus units aimed at large packs, so charging a sizable 6S LiPo at full current will take longer than on a higher wattage charger. The discharge mode is useful for bringing packs down to a safe storage voltage before putting batteries away for an extended period.

Battery compatibility

The charger supports LiPo, LiFe, and LiIon packs from 1 to 6 cells, NiMH and NiCd packs up to 15 cells, and lead acid batteries across a 2 to 20V range, covering essentially every common RC battery chemistry in one unit. This broad compatibility is one of the main reasons the iMAX B6 family has remained popular for so long, since a single charger can service LiPo flight packs, NiMH transmitter batteries, and lead acid starter batteries without needing separate dedicated chargers for each type. Selecting the wrong chemistry profile on any balance charger risks damaging a pack, so the onboard menu that lets you pick battery type and cell count is worth learning before your first charge cycle.

Build and power options

At 632 grams and roughly 144 by 135 by 36 millimeters, the B6AC V2 is a solid, bench sized unit rather than a pocket charger, and its dual AC/DC power input is one of its most practical features. At home it plugs straight into a wall outlet, and at the field it can run from a 12V car battery or portable power station, which removes the need for a separate power supply that many DC only chargers require. This flexibility, combined with SKYRC's reputation for accurate charging, is a large part of what justifies its price over cheaper clone units that copy the B6 form factor without matching its internal charging accuracy.

Bottom line

As a genuine SKYRC charger, the iMAX B6AC V2 offers accurate, well tested charging and discharging across nearly every common battery chemistry, with the convenience of running from AC or DC power. Its single channel design and 50W charge ceiling mean pilots with large battery collections will charge one pack at a time and should expect longer sessions than a higher power multi channel charger provides. For anyone who values reliability and broad compatibility over raw charging speed, it remains a dependable choice for a home or field charging station.
