Guys,
As an fyi I have decided to move to a North American producer of Batteries and Chargers, The chinese stuff is no longer feasible due to really bad delivery times and security issues having the product shipped in. 
That being said I am very pleased to announce that Immortal will be stocking 3000 and 5000 mah batteries from Tenergy, The batteries are heavy use for greater cycle counts and high power units for longer play times.
Along with this I will be stocking 3 chargers as well, 
 1. a simple low cost charger Nimh/Nicad charger for 6 to 12 volt packs, has a 1 amp and 2 amp charge choice
2. A quality digital programmable single pack charger that will charge/balance Lipo,Life, Lilo,Pb, Nimh and NIcad battery packs.
Finally an intelligent 4 channel digital charger that will do Lipo, Life,Lilo, Pb, Nimh and Nicad batteries, this charger will do 1 to 6s in Lipo and up to 15 cells of Nimh.

I will have all the technical data loaded on my site shortly.

Very cool news.

Yea I'm not sure exactly what's going in on China, but any type of decent battery is becoming a pain in the rear to import as of late.

Batteries and chargers are fully stocked now.
 these batteries I personally like very much
