Zippy Compact 4000mAh 2S 25C Lipo Pack

I bought this battery, after seeing a guy on youtube using it with his Hubsan H501S, and getting about 27mins flight time. So I thought, why not give it a shot? So I ordered one for my Hubsan H501S-S, same bird, newer version. Keep in mind that this battery does NOT fit in the battery bay of the quad. It has to be strapped to the under carriage. The extra 7 to 10 minutes of flight time, versus the stock battery's 20 minutes, giving you 27mins to a half hour of fun, is well worth it. It's a great battery. It charges, and hold it's charge well. I would definitley buy it again. Great seller also! Suggestion- If you put the stock battery in, strap this one to the bottom, and join them together with a splitter plug, (You can make your own, or order it from Amazon) you'll get between 40 to 45 minutes of non stop flight! Talk about fun!

A very good battery for my Axial buggy! I will buy again soon.

these batteries run for a long time. i use 3 of them for an electric skateboard. they work great.

Good little 2s pack for playing around

It is compact, however it lacks the to duration you would expect from a 4000mah pack. Also the wiring is poorly installed

It works great thanks

Big, heavy....bought 3 and only 2 were any good.

It gives my son/a nice little zip

una duración sobrada para aplicaciones que requieren gran capacidad, se echa de menos un poco mas de potencia de descarga pero para lo que la usaba va perfectamente

まだ使用してないのでなんとも、A&KミニミMk.2のストックにすんなり入りましたので、半日バラバラ射ってみて、またレビューを書きたいと思います。
