Hello everyone
I am the happy owner of a sailboat that I will be sailing full time, for the next few years. I am in the process of converting my lead battery setup to a Lithium setup.
I think I have found the right way to make it both affordable and relatively inexpensive.
If this is realistic, I will go ahead and continuously report progress here.
Before I get started, I want to hear you smart guys about / what I've overlooked? ... multiple angles on ideas often help with improvements.
Questions
In the optimal setup, the charge of LFP batteries should be controlled by current measurement and shutdown when flow goes towards 0A (0.012A).
In this setup, the charging voltage never exceeds 13.6v, but the chargers are controlled by voltage, not current.
1) Is it understood correctly that when BMS closes for LFP, then the chargers can continue to charge on start batt. - and that this setup is bulletproof?
- no overcharging of LFP
- no destruction of controllers and alternator
2) Is the insulator needed on the alternator?
3) will start batt. be sufficiently charged for me to count on it? (Volvo Penta md2030)
4) What elements have I overlooked in this setup?
5) Are there smarter ways to do this?
6) Can anyone recommend a DC / DC charger to mount on alternator (30A)
Thanks in advance ... Looks forward to your feedback
