Not found that myself. Re: charge rate, a bigger capacity takes longer to fill for a given input. If you want to charge faster you need a bigger input whatever the battery type. In the Coventry section we have some people running electric start machines from Lithium batteries charged by dynamos converted to 12 Volts. They work fine but if you drain a battery you would not expect it to be recharged by the end of the road.I believe they don't put out the grunt for long though..........Also don't they need a higher charge rate so the output from an Alton with the stock regulator is probably not high enough. That is the Alton is fine but a different regulator giving a higher output is needed.
Take a look at my post at this link: Lithium Battery in Dummy CaseCould we have more info on the types of lithium batteries that are giving good service, i.e. manufacturer and model number of the battery. please? Especially the ones that can fit inside a dummy battery box of standard dimensions and have the CCA to start a Comet. I have bought an Alton starter kit for my Comet which I am currently building up and would welcome advice re suitable lithium batteries. Many thanks!
Dear John,Big Ed; many thanks for the link. I was aware of the Shorai. However, other brands of Lithium battery have been alluded to in recent posts and I would be interested in hearing other members experiences with these. The Shorai batteries do not appear to have a BMS (battery management system) to prevent them being overcharged or over-discharged, both scenarios being dangerous to Lithium batteries. The Shorai also appears to have a cell balancing socket which indicates that charging via the main terminals needs to be accompanied by connection to a balancing circuit. More recent entries to the motorcycle market (and most lithium batteries incorporated in consumer rechargeable products) have these systems incorporated in the battery casing as standard. It is also possible to provide such systems externally. Have any members explored these or other options?
