I understand that float voltage is bad. but looking at chargegraphs for lead acid it's a CV/CC until it hits a voltage point then float charges.
Generally it's bad to float charge at 100%. but if float voltage was below the 100% mark the charger would only charge up to the max float voltage correct?
For example:
24v - 7S20P pack (max 29.4v)into a UPS which float charges around 27.3 would only charge the batteries up to a maximum of ~ 92%. If the float charge is CC does it make a difference? you can't get the voltage high enough.
I found a 24v 1500VA for free. or I can get a 3000VA XL for $250. I want to use it to charge my batteries from grid.
