I am in a bit worried and need some help.
Batteries (Marathon L6V160)
The manual for my batteries say that they should be charged at 2,27V per cell at 20°C.
I guess there are 3 cells in each block. 3 x 2,27= 6,81V
4 batteries in series (24V system) 4x 6,81= 27,27V
(The batteries can be boost charged is at 2,35-2,40V at 20°C)
Solar regulator (Tracer 4210RN)
The regulator can be set for only 3 charging options
GEL, SEALED and FLOODED (se attachment)
All three alternatives have a float voltage charge at 13,8V x 2 = 27,6V at 25°C
Hmm. 27,6V gives me 27,6V / 4 = 6,9V per battery and 6,9V/3 = 2,3V per cell which is way of the chart (se attachment)
Regulator temperature compensation coefficient = -30mV/°C/12V (25°C ref.)
My research tells me that the temperature differences just make it worse and that the charger will compensate the wrong way, giving me an even higher voltage when charging at 20°C.
I’m I missing anything?
Are my calculations correct?
Perhaps this isn’t a big deal or will I ruin my battery pack if I hook tis up?
Please help.
By the way, the suns just come out here in Stockholm
Have a great day
