Have some supersafe 2T1000MJ batteries wired for 24v. They only publish recommended float charge voltage 2.280Vpc at 20℃ or 2.265Vpc at 25℃
Setting configuration on Bluesolar 100/50 (easysolar 1600) I would assume a float of 27.18v @25degrees c. Can anyone tell me what I should be aiming for with absorption? Assuming keep equalise turned off?
Anything else I should be looking at changing?
Thanks
Hi @michael211
Those batteries appear to be designed as backup supply, and not specifically for regular cycling use. So if you're cycling maybe treat them as gently as you can. Typical pb's might use 28.8V for Absorb, so back off from there as you choose, depending on how fast you need to charge them.
I'm talking at 25degC, as that's Victron's base temp. You could use the 27.2 Float. Don't Equalize them.
Those figures suggest a Temp Compensation value of -3 mV/degC/cell, or -36 mV over 24V. That's ok.
