I have a ST 90 , wondering if 2 batteries wired in parallel would work . Batteries are game camera 6 volt 4.5 .They will fit in tray alright , but original 1 is 6 volt 5.5 . Question Is will amp’s double, will this be a problem with lights or coil ? I have a new style rectifier from DRATV

Thanks

Yes, more time spent at high RPM will be needed to keep them charged. The 90 CC stator is only capable of 62 watts at 5000 RPM and that was only when the flywheel magnets were the strongest many years ago.

Thank you . Just trying to get away from acid battery, the game battery seem to stay longer.yes the camera does not drain it so fast.

If it had an electric start, I dont see it taking long to get fully charged. I'm not real familiar with the 90, but the only thing causing a drain before startup would be the neutral light and brake light(when key is turned to lights). Yes, acid/leaker batteries suck.lol
