I know there is an excellent thread on
Lithium as a house bank but started this thread to focus on high
current applications (ie starter, thruster and windlass).
I don't seem to be able to find much information on people using
lithium batteries as a starter
battery.
I've seen plenty of videos with people starting cars with them and see they are prevalent as a motorcycle
battery so why not use them as a starter/thruster/windlass system on boats?
Also, it seemed to make sense to have separate lead acid banks for starter and house
batteries as the chemical makeup was different for deep cycle, but I don't think this is the case with lithium. So wouldn't it make sense to have one big lithium system?
The only negatives I can see at the moment are:
1. There might be some ignition protection required for other sensitive
electronics on the same circuit.
2. It would require a BMS capable of
delivery high
current (I do see inexpensive 200amp systems available).
3. It probably requires a small lithium "jumpstart" pack for emergencies or a reserve capacity switch.
Wouldn't the advantages of lithium and a
single bank outweigh this?
I'm very interested to hear peoples thoughts on this Thanks in advance.
