My shore power charger
is a Cristec 40A charger
. It is connected to my sterling alt-bat charger which then supplies the charging
for my 200ah lifepo4
bank. Works ok but this setup only supplies 24-25A at most to the Lifepo4
and the Cristec is going from boost to no-boost and lowers the voltage which actually stops the charging
completely (the sterling wants >13,5v to charge.) I also want to be able to speed charge the batteries
when stopping at a dock
filling etc. I also want to be able to start my Honda10 and charge at max for an hour.
To achieve the above I am thinking of doing two things:
1. Change the boost/cycle setup on the Cristec to be just a constant Voltage of something like 14. No stages.
2. Add a simple ad/dc adapter in parallel with the Cristec into the sterling.
I have ordered a Mean Well PSP-600-13-5
40A 13,5 V one like this:
and plan to set the output to something above 13,5v to satisfy the Sterling.
Combined the two should give me like 65-70A charge current
which fully charge my bank in like less than 3 hours from empty. It should also be possible for the 1kw Honda
to manage. If itís successful I might buy one more and put in parallel to have 110A if needed.
Any comments or thoughts of this setup? Anyone tried it already? I donít see the point of buying
an expensive battery
charger when I already have a device with a lifepo4 ďprogramĒ. The ac/dc thing was like 150 euro and thatís like 1/4 of a charger with the same capacity.
