I got my first Lithium battery
a bunch of years ago when I was looking for a 12 volt battery
that would fit inside the case of my old tar top 6 volt battery
on my Velocette. The only lead batteries
were tiny and they wouldn't last long. I got a Shorai 11 amp hour and it was like a revelation. All of a sudden my headlight was bright. The battery
would last all winter without a charge. The JG 12 volt converter and Lucas
generator seemed to keep it charged up.. I was sold. I started buying them for my other bikes. Some issues began to arose. My B50 killed them in short order. Don't know if it was the vibration or the charging issue, but after the second one on warranty I gave up on them for the B50. The special charger was a problem. If the battery
was low, the charger would tell you it was no good. Put it on a regular battery
tender and it would charge right up. I was told by Shorai that the difference between the chargers is that the special charger charges each cell individually, while a battery
tender charges all of them at the same time.
The killer for me was a Shorai in my '68 Suzuki TC 250. Had I read the Manual
, I would have known that it had a very primitive regulating system. I didn't, and I installed the Shorai. Took the bike out for a couple of 30-40 mile rides and it was fine. Used the bike in the East Coast Moto Giro. 80 miles out in the middle of nowhere, the battery
blew up. Of course the fact that I didn't properly research the suitability of the battery
for that bike and the fact that there were problems with the chase truck and I didn't get rescued for 9 hours isn't the battery
's fault, but it kind of soured me on them.
On my bikes where they are still working, they are remaining, but I wont be buying any more (except for the Velo).
