Title: Adding additional battery to bank - what/how to configure?
Post by: justinbowser on May 29, 2020, 03:16:03 PM
I currently have a 24V 600 AH battery bank composed of three 200 AH modules and a Classic 200SL with Whizbang Jr.  I have just received a fourth battery to incorporate into the bank bring my total to 800 AH.  Is there any particular sequence for adding this to the bank as far as the Classic config goes?

I currently have the new battery on the charger to bring it up to approximately the same voltage as the current bank.  I am thinking that one this happens I would hook up the new battery and wait until the CC is "resting" and then increase the battery bank size in the Classic config to 800 AH.  Does this sound about right?

i don't think you have to worry about anything. just hook up your new battery and increase the battery capacity in the midnite classic.

Yup. You did the smart thing by bringing all the batteries to the same voltage. If they are different the batteries will equalize to each other and with nothing to limit current.... but you knew that. Nice job.

The battery supplier told me that as long as they were withing a volt it would be OK but I got it within a couple tenths of a volt.  So far I'm liking the extra capacity! ;D

As Justin noted:

"From the WBjr main screen   ...    press the upper right button (Right Soft
Key) to take you to the first set up screen".

The Capacity setting is there.

The WbJr Manual,  is here:
