My charger has this function and works well. Ive noticed on many SMC packs cell 2 is a bit lower during high drain( not crawling but in the yeti) I was told this is due to heavy discharge rate and cell 2 usually drops a bit more. But matched resistance will tell you individual cells resistance. Ive never seen this in my crawlers though. I do set my lvc at 3.4v | |

A cells being mismatched is just them being cheap and not matching them before assembling. Something I expect and tolerate with my $10 packs, not $100 packs... It's not rocket science, it's chemistry. |

I ended up ordering 2 lipo alarms. He's gunna set the alarm to 3.6V and run the battery down to see where cell 1 and 3 end up when cell 2 hits 3.6V.

even lipos have lifespans of ~400 charges I believe. it's fun to use a pellet gun or .22 on a charged but bad cell pack. watch the smoke and flames to learn dangers of Lipo fires! |

IR testers are cheap, many chargers now have this feature. Quote:
