I have an EarthX Li-Ion battery on my Cafe' conversion. I have all my lights (except headlight) converted to LED's, and I have removed my automatic compression release and have a manual one. When I hit my starter button the bike starts immediately.....it does not have the delay that the normal bike requires. I have never had any issues with keeping my battery charged.
Our bike only has about 100 watts of electrical power when charging correctly. The headlight bulb takes 35 watts on low beam and 55 watts on high beam, the two front running lights are 8 watts each, the tail light is 8 watts....and ignoring the turn signals or 27 watt brake light.....the lights are using up 59 watts of energy. This only provides 41 watts to charge your battery. Converting the running and brake lights to LED's (2 watts each) will give you an additional 18 watts of charging power and change your charging power from 41 watts to 59 watts.
However.....you need to be a bit careful about changing over to LED bulbs if you decide to do that. A lot of the LED's are not as bright as the stock bulbs, and the turn signals and brake lights are not visible in daylight/sunshine with the LED's. A good set of bright LED's are not cheap......$ 22.95 each!

https://www.superbrightleds.com/moreinfo/tail-brake-turn/1157-led-bulb-dual-i...I have this tail/brake light in my Honda ST1100, and this bulb flashes when you apply the brake. These bulbs work exceptionally in brake lights that have housings with the lense that has the diamond pattern cast into the plastic - they do not work well in housings that have a nearly clear lense with a fluted reflector. The running light is far dimmer than the other LED's listed.....about 1/4th as bright, and you will not see the running light in the daylight.
