    Overall, I really like the pack. As long as it holds together and maintains a good life cycle I'll be happy. As far as performance, I honestly don't really notice a difference between this new one and the old ProTek.

    I did, however, learn something from the guy that built the pack. I had always stored my batteries charged because it had been ingrained in me to never store them DIScharged. Danny (from SMC) told me that he's stored fully discharged packs for "extended periods" without any problems. His suggestion was to just store them as they come off the track, charge them before use and don't store them charged. Apparently when the batteries reach a full charge, there's a chemical reaction taking place inside the battery. Leaving them charged causes them to puff just as much as storing them without charge.

    LiPo's: I would suggest a 'storage' voltage between 50% and 60% ... Don't know what charger you have Nexus but it might have a 'storage cycle' that will charge or discharge a given battery to it's storage capacity. I'd guess the better chargers do have a 'storage' function ... If you charge your batteries in the field then teh FUN way to do this is to simply run your car or whatever for half the time it normally runs for, say you get 6 min out of a certain LiPo then run for 3min which will get one near or near enough to it's storage voltage. However you ONLY need to do this for 'LONG term' storage, if your going to be running the battery every day it's alright to do as you friend suggests. And I can say for sure a pack will 'puff' if stored at full capacity as it's happened to me a few times. Smea personally as I usually don't know if I'm going to be running the NEXT day or a week, two weeks or a month later so I store my batteries at their storage voltage then charge when needed, but that's Smea ;)
