These Lithium Prismatic respond differently. I went up and saw the boys from SSB and we did a few experimental tests which they already new what the results would be.

We purposely overcharged one of these lithium SSB batteries. We put around 21V through. After about 9 minutes it was visibly getting hot and the case was melting, after 13 minutes there was a sudden explosion and a heap of white "smoke" but no flames. This lasted for about 10 seconds and then it was over

The white smoke was not actually smoke but a non toxic gas that is the by product of the severely overcharged battery finally giving up its will to live.

It gets very very hot, will melt you battery box but they will not catch fire. They are safe to send airfreight.

We then charged a lithium ion battery.... This time at 16v. It started smoking after 3 minutes and at the 5 minute mark it went bang! Smoke and blue flames, it resembled a flare and I'm told it can not be put out with a fire extinguisher or other methods and you need to wait it out until the chemical reaction fire burns out. It took about 3 minutes before it went out.

Scary stuff, so I'm glad I've got a prismatic battery under my balls and not a standard lithium ion battery.

Be careful, Lithium batteries are inherrenlty volitile, I deal with them a lot in my job. Saw a video of what happens when a cell (about the size of a can of Mother) was over-charged, it was cylindrical in shape and it went off like a bazooka! Blue, green and purple flames 4 or 5 metres out the back and they sustained for 4 or 5 seconds.

DO NOT OVERCHARGE LITHIUM BATTERIES OR THEY WILL EXPLODE

Owen.

So is the lithium battery voltage nominal 13.4v? If so it won't overcharge on a car battery (nominal 12.7v fully charged). What may be a problem is the charge rate (or how much current it draws while charging). I just spoke to SSB unfortunately though they could not give me a reasonable explanation as to how much the charge current should be. All they said was that you shouldn't connect unlike batteries together due to the different chemistry? wtf

It would appear though that if the lithium battery draws too much current it can damage the BMS (I'm guessing battery management system) circuitry inside the battery. I would suspect connecting another Lithium battery directly as shown in Walks link will also deliver a lot of current as these things can deliver well over 100 amps. Personally I doubt using a lead acid car battery to jump start and then using the bikes alternator to charge fully will cause any problems.
