Esky EK1-0188 11.1V 800mAh Li-Po Battery Pack for Esky E020/E515A Helicopters

Pros: It lasts longer than original battery, that came with Esky big lama! All cells charge perfecty the same rating and speed! Lift power is better also!

Cons: Size is about 2mm thicker than original, so it is hard to fit in battery compartment, but you can push it in with a little force or unscrew screws a little. No tools required except phipips screw driver.

Other: Better than original, and thats realy wierd from Esky! Pleasant surprize from DX, that clone is better than original!

Pros: - Does what a 3 cells lipo should do.
- Almost identical to the original(a little bit lighter in green color, label is clearly copied).
- same flight time with my old Honeybee Fixed Pitch v2.
- still working after 40 charges.

Cons: - haven't found any yet.

Other: Will but more if needed.

Pros: it's a Great investment, at least half the France retail price of the original one. The overall quality is very good.

Cons: flying time is a little bit shorter (8-10 minutes instead of 12-15 with the original one)

Other: great product for the price, be sure you fix it properly on your helicopter if you don't want it to move when flying.
