[QUOTE="Robert Watson, post: 105848, member: 38"] Lucas Rita ignitions draw a pretty big current. I ran one for a few years and finally changed it out to something more modern which draws way less power. If I recall the Rita would show about a constant 4+ amp drain which I could live with as I have a 200 W permanent magnet alternator for charging. I opted to try smaller coils that would fit under the mag cowl instead of the recommended pair of large Lucas 6V ones running in series. Even though the small ones were rated 3 ohms, they usually fried every 3000 miles or so. I have been with Glen and others when the Shorai has died. A pretty frustrating scene. I am afraid that unless there is a substantial charging system as Glen has indicated, I would stick with lead acid batteries, especially with that ignition. [/QUOTE]
