Doug, they are running about $300...

Thanks. saw the guys video. Very interesting. Don't want to mess with what I got already, so I need to look for a project worthy of onesunnbobb wrote:Doug: https://revivalcycles.com/
This post certainly discourages any thoughts of a Lithium battery for my bikes.ericheath wrote:Once I got my Lithium right to where it was getting a good charge, it spins my 1200 over easily. At first, it didn't seem to last long. Spun it over rapidly but in cooler weather only three or four bursts and she played out. If my bowls were a little low and I didn't choke it right away and get gas to the cylinders quickly, sometimes it ran out of juice before it started. I put the charger on it, because running them too low is a no-no. They do recover quickly though. I originally had mine set up to read actual battery voltage via a relay like lots do due to corrosion and voltage losses. With it like that, I think the regulator was seeing 13.2 or more at the battery and dropped the charge rate. 13.2 for a lead acid is still a positive charge from 12.6 volts, but for a LIFEPO4 it is minimal. It ended up dying a few times on me while riding. So I ditched the relay and it has been great ever since. (Two summers now) Their Achilles is cold weather. They hold an amazing charge just sitting in the cold. Last winter I would randomly check it and it was 13.6-13.8 volts all the time. Turn the ignition on for three seconds and it would fall quickly. Leave it five minutes and it would recover and then have enough to turn the engine over. They are a different bird.
When I came in from a 1-2 hour ride, I would check it and sometimes it would be 14.6 to 14.8 which according to the manual is too high. Turn the key and headlight on three-five seconds and it would drop to 13.8. Leave it until the next day and it's 13.8 volts. I think 14.4 is the recommended maximum charge on them.
I think a volt meter might be a very good idea with them.

This is why I like Bikemaster Lithium batteries. They have a built in equalizer and over charge protection board. Not sure about other brands.ericheath wrote:Once I got my Lithium right to where it was getting a good charge, it spins my 1200 over easily. At first, it didn't seem to last long.

Me too. Mine is still going. Six years now. Just wired it up No gadgets no gizmos.sunnbobb wrote:.... Mine is a shorei.
