I have two 12 volt batteries in series for 540 Ah. And, I have two more that will be connected all in parallel, but these two are not in use yet.
I am currently using the Phoenix Smart IP43 Charger, but it takes a long time to get over the curve on charging.
The parallel batteries are being charged with approximately 44 to 46 Amps from the single Phoenix IP43. A 12 volt (low power) blower fan is cooling the Phoenix when charging the batteries. 6 AWG welding cable connects the charger to the buss bar, shunt, buss bar, batteries.
Has anyone used two Phoenix Smart IP43 Chargers on a large battery bank?
Thank you.
