So I'm getting a new 2500RL and been thinking of replacing the Acid Battery with a Lithium 100 Amp, but NOT replace the charger or connection wiring.
I would for now just keep it as is.

Now I know that the Lithium Battery will not get completely 100% charged BUT I'm told it could get 85% charged on the standard charger.
Which would still be much better than what a normal acid battery can achieve at just 85%.

I'm NOT handy with electronics to install a new Inverter and Monitor, BUT I would be happy with a Lithium Battery that was charged up to 85%.
What say you? What could this hurt?
