SKYRC iMAX B6 (In-Depth Review)

The SKYRC iMAX B6 is a compact entry-level balance charger that doesn’t skimp on reliability and performance. Costing between $30 to $40, it offers plenty of value for those seeking a good balance charger that won’t burn a hole in their wallet.

The B6 is the smaller and more affordable one of SKYRC’s two most popular balance chargers (the other one being the bigger and slightly more advanced B6AC V2). It is also the more popular one compared to its bigger sibling thanks to its very affordable price tag.

  • Input voltage: DC11-18V
  • Circuit power: Max Charge (50W)
  • Discharge power: 5W
  • Charge current range: 0.1 – 6.0A
  • Discharge current range: 0.1 – 2.0A
  • LiPo/LiFe/Lilon Cells: 1 – 6S
  • NiMH/NiCd Cells: 1 – 15S
  • Pb battery voltage: 1 – 10P (2 – 20V)
  • Net weight: 237g
  • Dimensions: 107 x 85 x 34mm


The B6 is rated at 50W / 6A and can charge a wide range of batteries which include lithium polymer (Li Po), lithium ferrum (Li Fe) and lithium ion (Li Ion), nickel metal hydride (Ni Mh), lead acid (Pb) and nickel cadmium (Ni Cd) batteries. One useful feature on the B6 is that it can be powered using  a 12V DC supply which means you can use your car battery to power it outdoors when you’re having one of those long flying sessions away from home.

I’ve been using the iMAX B6 for well over a year now and I’m glad to report that it hasn’t let me down. It has a rather industrial look and feel with an all-aluminum casing and an excellent LCD display. Thanks to its metal casing, the B6 does not heat up much during charging. The menu system is also very easy to use.

When purchasing the iMAX B6, be wary of counterfeit products. Buying from reputable sellers such as Hobby King or GearBest is a good way to make sure you don’t end up buying a fake B6. Counterfeit chargers tend to feature FETs that are made using cheap materials and are less accurate when charging and monitoring battery cells. This can lead to batteries getting over-charged and not balanced correctly which can lead to high long term costs in replacing damaged batteries. Counterfeit chargers are also known to be unsafe due to cheaper parts and lower quality control.

The SKYRC iMAX B6 is available at GearBest for $39.90 with free shipping.
