Well these batterys r ran in spec TC 17.5 car and vta car that i am very competative with. Never ran them down near 7v much less 6v. Matterfact i havnt ever put in over 4500mah back in any pack ive ever owned. Actualy my tc pack is 99% of the time only getting2000-mah at most and 1000-mah on vta packs per charge
Packs r atleast 25c and most r 40-65c packs current ratings.
So yea dont think so packs have never been hot comin out of car. Packs have never puffed in car . I store my packs for 2-3weeks at a time wirh all my other rc gear still mounted in the cars unpluged at 60-75% charge. I just wonder if the quality of charger could have something to do with cell life ?
