Hi,
I am looking at buying new batteries for my venom NR2 and couldn't find what current rating the batteries would have to be. Also, the stock batteries are 8.4v nimh, would a 7.4v lipo work with it?

thanks

The 7.4 Lipo will work. Lipo cells charge up to 4.2V per cell and will be 8.4V when fully charged despite being rated at 7.4V

Ok thanks
do you know what c rating they would have to be (e.g 20c)

The higher the C rating the more easily they can sustain voltage under load in most cases. Also the lipo has an easier time in the heli as it can deliver what is required more easily.

Don't by the super over priced Venom packs....
for cheap lipos Zippy flightpower, or the Turnigy packs as well as Blue lipos are good for the $.
Hyperion packs are awesome and you can charge them really fast...5C charge rate.

You also need a Lipo compatible charger.

Thanks for the informatin
I am getting a lipo charger and was thinking of getting these

Do you think they will be any good? or should i go with a brand name.

They look fine from the specs...but thing is you can't trust the spec with unknown lipos. If many are using them and have good experience then sure buy them.

Personally cheapest I'd go is the known "no name" brands mentioned above.
