Hi,
i have 8x109ah 12v alphacell 220 gxl batteries that came out of cell towers.
they will be parallel as they are replacing 12v flooded batteries.
i am having some confusion about charge controller settings.
the only specs written on the batteries is the float voltage(13.5-13.8)
spec sheet
doing some searching i found a users manual
according to that page..
bulk/float: 2.27v/cell = 13.62
accept: 2.4v/cell = 14.4v
reading on the forums voltage should never be over 14.1 for gel batteries?
so i'm confused about this.
from the tracer manual default settings for gel

based on what i have read(and the specs above) shouldnt i be using something like this..

another question i have is i have a iota dsl-90 charger
the iq4 smart controller i had for the flooded batteries is not useable for gels(voltage too high)
would be ok if i use it without the smart controller and use the dual voltage jack plug.
the charger is only used when generator is running.
i can monitor the batteries via my shunt.
i was thinking of charging to 13.6 then 14.2(or vice versa) using the plug when needed.
maybe just charge to 13.6 using it and let the solar handle the boost?
thanks
