Our OEM battery is a large, heavy brick and the Lithium-Ion batteries are pretty small and lightweight. So if I got a 8 or even a 12 cell battery that possibly fits(OEM=4.45 x 2.76 x 5.12 Inches) I know that it can work to start up and all that, but would our rectifier be able to keep up with 8 or 12 cells? What I mean is, will our OEM rectifier be able to keep that kind of battery at full charge? Normally a regulator will stop charging a battery at a certain point so it won't overcharge. So how does our bike 'sense' how much charge the battery has and know when to stop or keep going? Will our OEM rectifier create that much power?
