    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

    They should do as you expect. Keep in mind that, if discharged, the charging time will be doubled as well.

    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.

    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

    When I had my ST90, I installed a 6 volt SLA (sealed lead acid battery) similar to the type used for backups and ride on toys. No Leakee.
