Handy charger – E_Sky Balancer Charger for 7.4V and 11.1V R/C Li-Poly Battery (EK2-0851) Reviews

Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

Pros:
+ Very cheap indeed. + charges 2S or 3S battery packs, each cell separately = real balancer. + Charge ends at 4.20V, quite exact. Manufacturer rated 4.20V +-0.1V. + Charge current is about 0.75A, BUT (see cons)
Cons:
- Charge current is about 0.75A, BUT it charges only one cell at time. It's controlled by a smart IC which is switching cells in cca 60 second interval.

- So the resulting charge time is 3 times longer for 3-cell pack.
+ The good side of this is that all cells are charged to the equal level - there's only one voltage comparator for all cells.
Other:
Bottomline:
Very handy thing, quite slow, but real balance charger with standard 2S and 3S DualSky / Align / JST service connectors.
