Hydrimax batteries

[Rcmaster199 at aol.com]

Chris, you might consider NiMH batteries from Radical RC. I have used their  
1650 ma 4.8 volt pack in my pattern planes ( on the second plane now) 3 whole  
seasons now. I bought two of these packs going on 4 years, but I still  have 
the second pack NIP. Used pack is still cycling very close to new, after  
about 600 flights, which is equivalent to about 150 charge cycles. 
 
Liked the airborne so much, I outfitted my 10X transmitter also about 18  
months ago. The 1650 TX pack needs charging only about every fourth  session
 
Radical has very good information on the care and feeding of NiMH bats and  
other bats as well on their website. I have found his information to be on the  
money.
 
Prices for Sanyo cell batteries simply are unbeatable. BTW, I remember  
speaking with him about cell differences at the Southeast Model Show in Georgia  a 
couple years back, and he explained that Panasonic cells (Hydrimax) do not  
have the internal robustness of Sanyo cells. He uses Sanyo only in his  packs
