i bought a x2 400 a few months ago. i noticed a couple of weekends ago both of my venom saddle packs were badly unbalanced, but i have 2 turnigy shorty packs which were charging ok, so i used them for both of my vehicles. now, they shorty packs are having issues balancing; essentially one cell charges to 4.2 volts quickly , the other takes a couple of hours to balance. for example:

the venom saddle packs are 3 months old, the turnigy shorty packs about 4 months old. I race at most once/week. i always balance change them and always bring them to storage voltage when i am done for the week.

i charge them at 8-10amps depending on time between heats, all batteries are rated at 5C.

is it possible that all of my batteries are going bad at the same time, or can it be something with the charger?

the charger reads version 2.01 when i go through the menus, i know this charger had a recall, i think its not affected though? http://hitecrcd.com/tectalk/septembe...tion-required/

thanks in advance
