Battery consumption

Given enough time it will probably happen. :p

I tend to be blunt as shit, and it doesn't always go over well. :)

Majority? You're being generous. :)

I'm probably just getting used to you, seeing you post so much. I've just started associating your presence with good things, like the diysolarforum.
 
Down in Melbourne 3 hours from home So havent started the individual charging as yet. Home tomorrow so i will get into it. While in Melbourne I picked up 3 X Vision 12V 200ah 57kg batteries at scrap value. Why 3 I don’t know, it should have been 4. I have these brain fart moments at times!

Hi Guys,

Just an update on my 24 x 170ah Supersafe batteries. They are all balancing nicely. Ive been through those that read low and gave them a good charge. ATM three strings of 4 have a balancer fitted and read in the 13.45 region during the day. The others are very close but well into the 13’s. Three more balancers are on the way.

Cheers.

Where balance matters and to what degree:
  1. Peak system voltage at end of absorption cycle - critical - can quickly damage batteries that are over peak voltage.
  2. End of discharge - serious - discharging some below others percent SoC-wise means those will deteriorate more rapidly.
  3. Balance in the working range - negligible
Essentially not worth checking the individual voltage unless:
  1. It's just before you start getting charge (maximum depth of discharge)
  2. Just entered absorption (peak voltage/current)
  3. Just before float (peak voltage/min current)

Yep, all good. None of the batteries were ill. Just needed individual charging. No batteries are going over 15v now and none low in float.
