im also speaking on actually using them too, a good hit or a sharp rock smacking one can set it off as well, sometimes theres just no reason.Decent charger with cut off limit. Properly set up and a lipo cut off on your car will help.
They are cheap yes but pretty good value. Ive got 4 of them from turnigy and not one problem. Of course if you abuse them a little bit it can go south. I have a lipo safe fireproof bag i keep mine in. I check them every few days for swelling, Sure as hell dont want my house or shed burnt down.
You mention two different things here:be warned guys, you really do get what you pay for in batteries.
id really hate to see a baja go up in flames from a cheapo pack.
for those who dont know what lithium batteries doe when you damage/overdraw/overcharge them...
Hobby King always has Crack Deal prices on Lipos.Just found these.
Wont last long. LOL. They'll sell off fast.
