Li-ion Battery

Doing a cafe racer style restoration on my 76 KZ750 twin so I'm trying to hide all the electrical bits I can. I'm looking at an Antigravity AG-801 li-ion battery which they say has 240 Crankin g Amps and 9 Ah. Does anyone have any experience with Li-ion batteries in general or specifically this one? I know I need to get an up to date regulator/rectifier. Scecifically will this be enough to use the electric start on a big old twin ?
Thanks

That's not entirely true. You can use some regular old trickle chargers on some Li-Ion batteries. My Ballistic battery says that there are a few regular trickle chargers that you can use on it, the Battery Tender Jr. being one and luckily for me the one that I have. But a traditional trickle charger treats the battery as a whole. A charger that monitors each individual cell and evens out the charge across all of them, Ballistic does sell their own - and obviously Ballistic recommends it, is preferred for Li-Ion batteries. That said, I've had my 8-cell Ballistic on my KZ400 for about 2 years now and I've always used just a Battery Tender Jr.

What I really want to know is if the 8 cell battery has enough grunt to start the bike, goodness knows my 61 year old arthritic right leg doesn't.

Another important note: Although the Battery Tender is known as a maintenance charger, this is not the case if hooked to a Shorai battery. Because of the voltage differences found in a Lithium battery pack, the charger may not enter "float" or "maintenance" mode. Rather than simply keeping the battery at a proper float level, it may stay in boost mode for long periods. There is then the risk of overcharging the battery, one of the many - See more at: www.batterystuff.com/blog/can-i-use-a-ba...sthash.XBCELpQR.dpuf

When I heard of lithium batteries being used in motorcycles I thought, OK, so there must be some special balance charging circuitry built in. The lithium-ion battery packs in your laptop aren't just dumb. They have charging and monitoring circuitry often built into the pack itself.
Anyway, it turns out that even those $300 Shorai lithium batteries are just dumb packs like you'd get if you used an RC lipo. Shorai has a terminal on the battery for balanced charging and sells a charger to connect to it, but this is not meant to be used on the bike. You have to plug the thing into the mains to recharge it. Good luck on your roadtrip...

Which is the case with the KZ. They can charge up to around 15.5 v.

If your charging system is charging at 15.5v. there 's something wrong with it, & you can cook ANY 12v battery, it should charge between 14.2 to 14.5spdygon wrote: Also u have to make sure your charging system does not charge over 14.4 volts.

I check mine every 3-4 weeks and I am always amazed how for the electrolyte level has dropped.
