Civic VX MPG project (Delete Alternator, add solar)

[VXmpgRacer]

The car wasn't lowered at all but looks very low. The coroplastic front lip will bend out of the way when it hits stuff so I made it pretty low.

very nice

I finally got the large deep cycle battery installed. The charge controller is now right behind the Emergency Brake so I can see it from the drivers seat. Under the charge controller is a fuse block to help prevent a fire.

If you have speed bumps or deep dips like I do, it'll happen to you too, likely. I now have a new dam and side skirts and I stay a little further off the pavement.

The battery is rated at 210Ahr.

This project is just starting the testing phase. I disconnected the alternator wire and it is only using solar to charge. Hooking a charger to it at night is an option.

The battery and box are well secured with two ratchet straps.
The Valve Regulated Absorbed Glass Mat battery is meant for confined area's with poor venting and is currently vented directly to the cabin.

Wow!

I hope I can be some help for the plan/testing, having had a deep cycle battery and alt delete running for almost a year. So my questions are in that spirit: Won't a 210 ahr battery need at least a 90amp charger or an equally powerful alternator to get a true full charge? With less, won't the battery degrade in its ahr capacity kinda quickly?

SunRNR has done a lot of research on this combo of solar panel, charge controller, and battery. I trust that their system will hold up well.

I have not heard/ read about ah losses due to low amp charging.
I am still under the belief that slow/ low amp charging is superior to fast / large amp charging. In short the fast charge is reported to dissipate faster.
Could you enlighten me with some information or a link ?
I seem to have a gap in my knowledge bank.

Charging batteries fast wares them out like discharging them fast.

Charge them as slowly as you can get away with.
