But I have run into a problem. I cant seem to find any lightweight
batteries capable of making the trip. I need more battery capacity, but
it must be lightweight.
I do have solar panels onboard to recharge the batteries, but due to
weight limitations, I can not use enough solar panels to keep up with
battery drain. However, once on the moon, given several days, the
batteries will be fully recharged for the return trip.
I think you're trying to do to much in the early development of your craft.
Pioneers in rocketry quickly decided that the way to go was to drop off
unneeded bits of the vehicle on the way. I think you should consider
that. Once a battery is discharged, jettison it. This will reduce the
power required to get the remainder of the vehicle further on its journey.
Once you've landed on the moon, you need to consider whether to dump a
whole load of batteries, and just return half of the vehicle back to Earth.

Good luck.

PS: Gasoline has a MUCH higher energy/weight ratio.
Are you suggesting we should drive to the moon? My twenty year old truck had enough miles to make it to the moon. I think if it hadn't been wrecked it could have driven back too. Not sure if it would have done the trip so easily since it is mostly uphill. That can be a lot of strain on an engine and the downhill would be hard on the brakes. I'd have to stop several times to replace the front brake pads.
