Up in flames!

One of the guys in the Sondors group did an upgraded battery and controller. Before you go bonkers, this upgrade has been done successfully by many others and without drama, so the upgrade parts havent been a source of trouble. He goes out for a ride and everything seems to be OK and then it goes pop, pieces of battery go flying, rider makes a hasty exit off the bike and there it sits on the ground....in flames...!!

Lots of discussion over whether it was an install issue or a battery pack issue. We may never know due to the damage done.

Just a reminder to NOT skimp on components and connectors when making your own e-bike better. Do an excellent job and enjoy your ride.

I've heard a couple of stories lately about "quality" batteries igniting suddenly. Mine are headed for ammo cans as soon as I can get to Harbor Freight.

It is hard to tell what happened from a pile of ashes.

This came from one of those little 4 pack lithium-ion headlight battery packs.

I don't remember exactly what happened. I think the pack stopped charging properly. Loose connection?

Anyway, as I was looking at it, a short occurred, I think where the uninsulated bands went around the corner of the battery. The insulation on the battery pack immediately burst into flames, and was only extinguished after physically breaking the circuit.

Looking at it closer, one of those two bands was apparently positive, and the other was negative, neither insulated, so brush them together, and poof.

Moral of the story? Don't get shorts in the battery pack as the insulation will burn and they will cause a fire.
