Well, my tenergy (cheap cell brand) battery just vented. Lots of smoke. Sizzling. 5 minutes after the smoke stopped, the temp was at 301 degrees F. This pic was 5 minutes after that.

Suddenly I'm not so afraid of a LiPo blowing up on me

the lipo would be ok... becouse that bat does not have enough current... becouse the cells were over heating and... explodeing... it was drawing too mutch current and heating up.

and jeez that would have sucked... lol i made a battery out of electrical tape too!!

what did you do to the battery to begin with? Thats not how tenergy packs come... you definitely did something wrong there.

Had the batteries been in SxS form and not whatever you did to the pack, it wouldn't have overheated, vented or exploded.

no, tenergy packs are very cheaply made. I was asking for it putting them in brushless and it's a few months old

You clearly do not understand. YOU are what caused the pack to fail. You did not have the pack in Side by Side form, and you had it wrapped thick with electrical tape... how can it let heat out? What you did to your pack, is why it did what it did.

They are sport packs with spot welds... normally you don't ever want to use those in high current draining brushless systems.

Its best to buy tenergy cells unassembled and make your own packs. You also want deans connectors for sure. The cheap molex connectors can melt in a hurry, and when that happens, you hope that it doesn't create a short.

I've got a ton of tenergy packs i'm disassembling to turn into SxS packs for my vehicles. I initially bought them to become a dealer, but I'm going to end up using them as hump packs for 1/5 scale and also as midrange club packs for our local track in SxS form.

yes, I know, I was going to put them in sxs this weekend. let me just tell you that I know of many people that use tenergy for brushless.

I use deans. I've been looking at brushless for close to a year. I would never use tamiya connectors for brushless...........or any rc for that matter

your electrical tape is why it vented.

Heat shrink tubing is what you should have used instead.

What does SxS mean? Is that where all six cells are sideways next to each other like [][][][][][]
Not like:
[][]
[][]
[][]
And are Tamiya connectors really that bad?

Pay attention to the current rating of the batteries and keep ventilation proper. You were the cause, not the battery.
