I did a one night wild camp which resulted in my Victron shunt app reporting my my leisure batteries level at 66% the next day.
Just as an experiment I wondered how long it would take for the engine on tick-over to bring the batteries up 1% at a time (I have no B2B)
Started at 66% after 8 minutes it went to 67% (it was showing just over 5 amps going in then that dropped to around 4.7-4.8 amps)
After 15 minutes I couldn't believe it, it had suddenly jumped to 100%!
I thought this is great if it wasn't a fluke, I don't need the B2B I had planned on getting and with just a 15 minute tick-over during the day I could wild camp indefinitely.
So with my 100% batteries I spent another night wild camping and the next day it was down to 66% again.
Tried a repeat of the experiment the day before but this time it never went higher than from 66 to 68% and I left it for over 30 minutes.
Does anyone know what could be going on here?
I also have a meagre 100w solar panel but don't remember if it was sunny on the first day and not on the second.
Is it possible for the alternator to recharge 2 110 a lithium's from 66 to 100% in 15 minutes or is the victron app lying to me? (although if it was it seems strange I had 66% left after the 2nd night I should have only had 33%.
Any ideas?
