lithium ion car and motorcycle batteries

I now have to wonder if the Li motorcycle batteries have a more sophisticated internal circuit board to help manage the charging form a standard car or motorcycle type of system.[/QUOTE]

Well the typical cycle batt with 25 min reserve, and 575 cranking amps is about $125

Now that the particulars of charging/discharging a Li pack are known, i also wonder if there is circuitry inside it for charging. For the price i would think so, plus most motorcycles the batteries are tucked away inside the frames lots of times under the seat. With no air circulation to keep them cool.

A HD softail has the battery under the seat, and the oil tank wraps around it. I would say thats a pretty hot environment.

I would imagine all the lawyer issues these companies would have if some biker got him a hot seat from a thermal runaway on a Li pack cooking his butt. Lol "baboon ***" comes to mind.

But it is a serious thought. Is there circuitry internal to these to maintain proper charge / discharge rates? If these batteries have this internal setup, then with the charging system i will be using, wouldent just linking 2 or 3 of the bike batts together in parallel work?
