Thermal battery in my Provari!

[seanmc]

Had a Panny go thermal in my Provari today...burnt the crap out of my hand! It was the magnet spacer that lost its charge, slid to the side and grounded out the positive. Well...to make a long story short, the thing started hissing, smoking and buring hot...then collapsed the spring. I popped out the battery put a new one in and it works like a charm! These PV's are resilient!

Yikes! Glad you are OK.

This is a good demonstration of why the manufacturer recommends against spacers. AW IMR Button tops FTW!

An xtar battery spacer is a better idea if it fits - centre conductor and insulated outer.

Yeah, looks like I'm sticking to my AW IMR's! It's crazy because this is the second time this week that I had batteries go thermal on me. Earlier this week, I was salvaging some Sanyo 18650's out of some laptop batteries for my flashlight and had a positive and negative wire touch and stick together...man, that could have been a nightmare because I had a 12x18650 pack go thermal...I took it outside and chucked it in the driveway, then continued to hit it with a shovel to try to break any connections...haha, I'm done being a cheap ..., I'll stick to Super-T for my batteries from now on.

When a manufacturer wisely makes specific battery requirements, why would anyone use a magnetic spacer, cheaper battery, etc. Not only is this a safety issue, it voids the warranty.

Using spacers with batteries in metal tube APVs is definitely risky business

I'd be a little careful in suspecting just the magnet, very well might have been something else. They generally don't lose their "charge". High heat could cause a neutral condition, might have went thermal first from something else.
