Hi guys
I recently bought myself a BlueSolar MPPT 150/35 CC to use in combination with a battery bank, consisting of 2x 6 V gel lead acid batteries (for golf carts): Golf Cart TAB Motion Gel Batteries (https://www.tab.si/index.php/industrial/display_smalltraction/4 ).
Now I ask myself the question how to determine the right determine absorption/float/equalisation voltage for this type of batteries. This link (https://chargetek.com/basic-information.html ) gives like a general rule of thumb for lead acid batteries: 2.25/2.4/2.55 V/cell ==> 13.5/14.4/15.3 V
I found there's a pre-installed program for forklift batteries: PzS tubular traction (1), 13.8/14.9/16.7 V. As forklift batteries are more or less similar to golf cart batteries and these numbers more or less look like the ones I found above, I intended to use this mode. However, I'm not quite sure if the batteries are tubular, and if that even matters.
Is there any other (experimental) way to determine these voltages?
Also, I read that it is not advisable to equalise gel batteries, is this right? Why not?
Thanks in advance!
