Chinese LiFePO4 goes pretty cheap, but that's not the end of it. He'd also
need at least a BMS, and probably a new charger. (With some electronics
background, he might be able to hack up a way for the BMS to control the C-
car charger.)

How can a maintenance free battery that doesn't cause corrosion be
overkill for him?

I had Sams Club batteries in my S10 EV (20 of them) for my first pack.
They were Energizer EGC2 batteries. (The cost was around $1700 5-6
years ago.)
They lasted 2 years with good service, and I eked out another 3/4 of a
year with reduced range/capac

It hasn't been stated clearly the Li cells have greater functional capacity

You can fill the lead acids to the brim and they on't be hurt, but I

I believe lithium is now about twice the price of lead for similar
