jp79er Posted September 29, 2014 Share Posted September 29, 2014 Stupid me. When I went out today I took my LiPO and after I had finished thrashing around the park it went in to the skate park....where it took a bit of hammering, go back to the office and thought I had better check the old lipo, and I have cracked the case...DDDDOOOHHHH.....I have taken the case apart and all three cells look fine no sign of puffing or anything. So have put the hard case back on and then taped it up solid..... It was about half hour between taking out of the car and checking the cells.....would I have noticed any puffing with in that time? or seen a problem... Hoping its all right, should teach me a lesson, as I had the 3 NiMH's in my bag and should have just swapped it over before taking on the jumps.....

Oh How Original Posted September 29, 2014 Share Posted September 29, 2014 You most probably would have seen if it was puffed up... Your best bet for future reference is to just wrap them in some adhesive foam and a bit of duct tape just to add that little bit of bounce.

jp79er Posted September 29, 2014 Author Share Posted September 29, 2014 It has adhesive foam padding blocks only a couple of mm think top and bottom and its held pretty fast in place...but coming down from about 6ft straight on its tail on the concrete probably not helped...lol..but the car took it well i was quite impressed..

Oh How Original Posted September 29, 2014 Share Posted September 29, 2014 Presuming that means 3s lol, 3c would be 3 current, 3s is cells (even though it's spelled with a C) to avoid confusion. In fairness though, if the LiPo is puffed to the point of being dangerous it would bend the case anyway so theirs no real reason to open the case up. It'll only void the warranty if you ever need to use it. Quote Link to comment Share on other sites More sharing options...
jp79er Posted September 29, 2014 Author Share Posted September 29, 2014 damn that 3s/c rubbish.....i'll get it right one day....LOL To be fair the I opened the case as the crack at the end allowed it to be spilt open a quick check closed and taped up...

Nitroholic Posted September 29, 2014 Share Posted September 29, 2014 If a cell had been damaged then it would puff up fairly quickly. Keep an eye on it when you charge it ( should do that anyway ) Not all hard-case packs are equal in terms of strength. I have some of the Turnigy 2S hardcase packs that cracked very easily in normal use. No skate park ramping....just relatively slow speed impacts on a well secured battery, and the pack's case cracked. I'd probably charge it and give the car a run with the shell off ( just in case ) and see if it's all OK. I would think the pack should be fine though. Running a pack through with the shell off would allow you to see any problems sooner, and get the battery out quicker if you had to. Quote Link to comment Share on other sites More sharing options...

nr73 Posted September 30, 2014 Share Posted September 30, 2014 This thread has made me think (for a change!). My rock crawler has the lipo mounted down between but behind the front axle. Quite easy for it to get punctured on the corner of a rock there I reckon, and then I'd have to spot it straight away and somehow get the lipo off the car before it went up in flames. I think I'm going to make an alloy guard plate for it to sit in now. 2 Quote Link to comment Share on other sites More sharing options...
