Hi I have just bought 5 x 106Ah (530Ah Bank) Victron Lead Carbon batteries for my boat and want to programme the correct charging settings on my Cerbo GX/ Shunt. Can you advise on the correct Victron Connect settings via the shunt i.e.:
What the following settings should be:
1 - Charged voltage
2 - Tail current
3 - Peukert exponent
4 - Charge efficiency factor
5 - Current threshold
Can be a bit confusing. I have the same batteries in a 24V configuration. These settings work well for me, but you may need to tune in line with the advice in the video
Absorption 14.1
Float 13.5
Temp comp -12.00mV/C (guesswork, can't find a published figure)
Charged voltage 14.0
Tail current 3% (configured for solar)
Charge detection time 6m
Peukert 1.25
Charge efficiency 95% (probably too high, 85% probably better as I don't use much of the capacity)
Current threshold 0.1A
Use at your risk and please let us know if there's something wrong
