Due to an error on my part, two of our packs went way under voltage. No physical signs, but both seemed to loose some steam.

It could be that both my son and I noticed the same thing coincidentally. Or, does a single undervolt situation have that much of an impact on the pack?

1 pack is new, 1 has 10 race days on it so 50-60 cycles.

Trying to decide if I need to order new packs ASAP or if the damage will shorten their lifespan at the end?
