I have a Skylla IP44 12/60(3) running two banks of AGM Super Cycle batteries. The battery banks are not holding a charge (voltage drops prematurely under load) and I've been advised by my Victron distributor to try equalizing the banks. The equalization voltage is set to 15.9V, but when I put the charger in manual equalization mode it won't put out any more than 14.6V. Charger state is showing as "Equalize" on my CCGX.
What am I doing wrong?
Hello.
What is the load level under this situation (is there any load)? If your load is more than (or close to) the output of your charger then the voltage will be held back. Are you able to try the equalisation with the banks isolated from any loads?
Cheers
The load was nowhere near the charger output. One bank had 5-6 Amp load, the other had no load at all. It's a 60Amp charger.
What current is the charger putting in? If it's maxed out then perhaps you have a dropped cell in the bank. This could explain both the low voltage when trying equalise and also the fast voltage drop under load.
