Contact Shorai, they usually stand behind their stuff and will replace it and help you figure out why it happened to prevent it from happening again. We have seen that type of issues on a few other members bikes and they seem to always get a good resolution from Shorai.

That's good to know Mike. I got men when they were first started to be promoted at my local motorcycle shop in Durham NC. I was sort of their test subject, also good friends with the workers there. I like my battery so much that I pretty much promote it, brag about it, and have even talked people into getting them. At no benefit to me mind you. I just like my Shorai that much. Prior to this, I was replacing batteries almost yearly and yeah they are expensive, but this one I have had more than paid for itself. I love how it cranks my bike to life even in cold weather. I have NEVER put tenders on it, NEVER had to charge it up over the winter. No joke. It has been very reliable to me. This year my goal is to put one on my 72 CB450.Maritime said:
To the original poster: I hope you figure out what happened, whether bike related or if it indeed is a battery issue. I'd like to know the outcome.

Good to know Eddie. One of the longer term members here, Tyler I think had on on his 90's yamaha and it literally caught fire and burned up the back end, Shorai covered the repairs to the bike and gave him a new battery, it had a bad circuit inside, they had a few like it over the last few years but I have always seen a positive outcome. I will be getting one for my bikes soon as well as I had 2 regular batteries go bad this summer while I was laid up in the hospital.

Fuck You.
Seems their overcharge protection likely failed. If so they will want to know about it before it hurts someone or causes a crash and they are in deep trouble.
External overcharge protection normally cuts power to the battery so there is no chance of an explosion.
I know a guy that left his cordless drill battery charging all the time on a "Smart" charger. The charger malfunctioned and the battery blew up, starting a fire that consumed his entire shop.
I am not a fan of battery tenders either for this reason.
External protection has only one job, to prevent overcharge or over-discharge and the protection is redundant, meaning if the unit malfunctions it is the same as going into 'protect' mode.

On another battery note. My wife broke the back of her phone and I ordered a replacement. It is an LG Nexus and has a glass back, really shit design imo. Anyway as I was removing the cracked back I noticed the reason the back had cracked is her battery had swelled and put pressure on the back. So I also had to get a new battery, third one to go bad and it almost ruined the phone. She needs to upgrade but these lipo batteries can fail in spectacular fasion. Had she charged it longer I bet it would have popped.

Just got off the phone with Shorai. They are expediting a new battery to me. When my battery blew I asked the tech what was the clear liquid that was steaming and oozing everywhere and they advised it is a electrolyte solution within the battery that the energy travels through. She said that these batteries are very tempermintal on charging and discharging which I knew. She said once a cell (i think thats what she said or it might have been a diode) goes bad it is just a chain reaction and the electrolyte solution will overheat and penetrate the case.
She advised that if for any reason the battery falls under 13v while at idle, once you rev the engine it will charge the battery "too fast" which can cause this. Damn these things are tempermental. I guess I will have to go pick up a tester and start testing with a agm battery I have here. This sure makes me want to go back to agm and forget about the looks...

Ok so did some minor testing on the bike. All lighting is shot and I redid the wiring harness enough to start her. Luckily the ignition is still functioning. My reg/rec is blown as well but am not sure if the battery explosion caused it or the other way around. I am going to order a mosfet style one that someone posted on page one.
