The problem is with the batteries becoming over-charged or over-discharged causing metallic lithium and oxygen bubbles to form. They react together and cause a fire. Either it's an issue with the protection circuitry failing to shut down the batteries when they are at max/min change (possibly an EE issue) or it's an issue with the batteries themselves not charging correctly such as reporting a false voltage and continuing to change or discharge (manufacturer issue). The latter is more likely since lipo protection circuitry is so common now they don't really need to reinvent the wheel, but trying to add an extra 1000 or so mAh to a battery could definitely cause a problem.

I'm running out of space.and use for them. I have a ARM based board I hacked into an internet radio player.
A Raspberry PI in a retro-arcade setup. A 5? year old i7 running Win7 (Why upgrade the CPU? It's the graphics card doing all the work in my rig),
Also I have a cheapo tablet I use for watching Youtube while enjoying a bubble bath.
There's just no point in buying any more or upgrading an entire computer at this point.
