I have a question that may seem odd, but I am really searching for an answer.
I have several 37 volt lithium ion bicycle batteries that hold a lot
of charge after being recharged through grid outlets.
I also have an old RV that uses 12 volt appliances run from 12 volt
lead acid batteries, and solar panels on the RV roof, feeding the 12
volt batteries.
Now I wonder whether the following idea makes sense: to connect two
empty 12 volt batteries in series so they be a 24 volt bank, and then
connect one 37 volt lithium battery in parallel.
The idea would be to drain the charge of the 37 volt lithium battery
"downhill" causing the empty 24 volt system to become charged,
hopefully without much wasting of energy.
