Hello,

Let me say up front that I LOVE my TrackPower 4900 batteries...they have been amazing. Anyway I've got two sets of two packs which I use with my E-Truggy. They are labeled so they always stay together...anyway tonight I was packing up my gear for a race tomorrow and I noticed that one pair didn't sit flat on my table. They had a very slight bow to them. It was so subtle that I didn't really see it, but I can tell very easily when I put them on a flat surface. The case isn't cracked, it's very subtle.

Anyway what do you guys think...are they safe to use? Does this indicate the packs are damaged/defective? I have emailed Duralite support (tonight) I just don't expect an answer till Monday at the earliest.

I've been using LiPo packs for 3 years and I'm well aware of the charge/discharge rules. These packs (used in a 4s config) have never been below 13.75v, most of the time they are well in the high 14v range (14.7+) when I finish the races and recharge them. I also balance them each time I charge...

Any advice would be appreciated, I will post when I hear back from Duralite.

Thank you,

DM
