ran my twin avenger today. 4082 1600, seaking 180's, 5s2p wired for 10,000 mah. ran first 2 sets of packs. ran fine. 3rd set ran a little low on power. brought it in after a minute of running. 5mm bullets to esc at motor end were hotter than normal. 120 degrees. 1 of the bullets were loose. battery sustained this damage. got hot at the wire connection to battery. readings on cell checker were 3,765, 3.774, 3.755. should I replace batteries after I fix bullets to motor?

you only have 3 battery check readings, need 2 more. -
bad connection
sorry. misread. as follows 3.765, 3.768, 3.750, 3.770, 3.752.Originally posted by rol243 View PostComment

I would cycle the battery and see how it is. It has two motors this hull? If so and one side lost a connector than the other ide would've worked harder and boat certainly would've been slower. Was there a cool down period between runs?Comment

those cell readings seem normal to me , naturally not fully charged to 4 plus volts but certainly not in the danger zone . i storage charge my packs to 3.8 volts per cell.Comment

For the insulated wire to get hot enough to melt heat shrink, the tab must have been a LOT hotter than LiPos should get.
I would treat that pack with extreme suspicion.Paul Upton-Taylor, Greased Weasel Racing.Comment

yes twins. first 2 runs were fine. 3rd run was lower power. brought it in after 2 minutes as I thought these set of packs were just not as good as first 2. never had a set of packs that ran lower. next time i will stop run immediately. yes, will keep a close eye on this set of packs. thanks everyone.Originally posted by srislash View PostComment

I think i will solder my connections from esc to motor. when I built this boat all bullets to esc from batts to motor were tight. I put a little electrical tape around the connection to prevent any arcing. how does a bullet loosen up?Comment
