RE: JR 10 X
Crap! I bought two of the 1500 Life for my JR X9503 and XP9303 now they have a 2100!
The 1500 version I have run my X9503 for almost 8 hours. Almost no self discharge in storage. I am sold on this chemistry.
I have Life in all my planes now too. They seem bulletproof. Just do NOT push them to the edge. At the end of their discharge cycle they fall off like a rock off a cliff!
I charge my transmitter packs after every two or so flying sessions. I am nowhere close to a third discharged.
To be fair, Nimh has served me well for many years but they do discharge in storage and can't be charged nearly as fast. In my airborne packs I have had some nimh failures, one on a new pack. With the A123 packs I use in my planes I have had zero problems with eight packs over the last 3 seasons.
