I upgraded my in the floor battery to the ping 60v 20ah battery, it worked great for a week, and my bike was noticeably faster and better uphills.. till it almost killed me.
As I was riding along I heard a loud pop and my my battery box caught fire, pretty large stinky blue/purple flames. could have taken the whole bike down, I called 911 on my cellphone just as it was running out of battery power and the fire department came and put out the fire and took the battery away...
$1000 wasted on my ping battery. I was so scared at the time i did not think to try and get a photo before the fire department took the battery away so I'm pretty sure ping wont be able to help me / give me warrantee.
Everything was connected via big anderson powerpoles, my controller is fine, and i was able to pop my lead acid battery back in the bike and reset the breaker and replace a fise and it works fine... weird
just wanted to let everyone know before buying the ping 60v batteries,
