[RE-wrenches] Integrating Lithium batteries with legacy inverters.

[Jerry Shafer]

Wrenches, William
I have installed quite a few memory saver kits in the old SW Inverters, ask
around if there are any kits still around. This is a viable solution to the
Li batteries. Here is something else, the BMS's should protect the
batteries anyway, in part of my testing we did this using cheap chargers,
overdriving the CC's good BMS's disconnected to protect the cells.
Bringing back fun memories of mayhem and destruction,
