Default Re: Doable or dumb?

Batteries from different manufacturers may have different 'chemistries' which will determine the terminal voltage and charging voltages.

I would imagine that even batteries from the same batch of a production run from one manufacturer would have slightly different terminal voltages and Amp hour capacities.

Hopefully you already have an intelligent charger that will limit the current and both the fast charge and float charge voltages.

A balancing charge will be required occasionally.

If I were in your situation, I would be tempted to buy four cheap LED voltmeters and put one across each battery.
You could then monitor the voltage of each battery during charging and discharging.

I would not replace the Powerline batteries until I saw signs of age or failure.
