Looking for a new Batt for the ZX being as the old one is out at the mo waiting for a replacement subframe from the states. The old one is still OK but being as they're so cheap thought might as well waz a newun for next season. Don't want a Lithium unit as don't want to have to buy a new Optimate so the question is who makes the best conventional Batts which will work with a standard Optimate 4??
Get the Lipo anyway, had mine nearly a year and not ever needed to charge. During the summer both fans are on pretty much all the time ( got a manual switch) and like clockwork always starts on the third turn. If your worried about discharge just disconnect after each track day.
Oh aye yeah! I'll take two at that price! Super B 5200 Lithium-Ion Li-Ion Race Motorcycle Lightweight Racing Battery | eBay
