Zippy Compact, the latest addition to our Zippy battery series offers excellent performance and high quality in a "Compact" size. These packs provide the same capacity and discharge rate as our Flightmax line, but give you alternative sizes for applications that require a specific shape.
Great for models with limited battery compartment space!
Zippy batteries deliver full capacity & discharge as well as being the best value batteries in the hobby market today!
Bought this pack to replace the dry batteries on my CTB6. It is just a tad thick but for the price I can live with just attaching it with velcro and leaving the battery door off. Only other pack I found that would fit with the door was about 16 bucks so this was a no brainer.
Quality looks good and so far a single charge was left on for 5 hours before i got tired and turned it off and it was still 3.8 volts lol...
So if you are looking for a pack to replace TX batteries this one is a good deal.
