I have a Beta 50hp 600 hrs
Alt is Beta supplied 120 amps internally reg.
600 ah
Lithium
900 ca lead starter
battery
Alt goes starter then Blue seas 2 circuit on off with combine function.
Good
wiring with
fuses each side of
Victron 50 amp dc dc.
Victron is wired back to switch and lithiums
What is happening is that the alt is
charging at 13.4v but when the dc turns on the input voltage drops down to 9 v and the dc turns off.
When I combined the
batteries the alt charges at 60 amps at 13.1v
Start
battery resting voltage 12.4v
Everything worked fine the first time I tested
But later that day this occurred.
Any suggestions?
Regards
