Engine not starting – Ground Fault?

[BOAT]

Those small Lead Acid batteries we use only last about 3 years max. They make some really nice Lithium batteries the same size and the engine does put out over 14 volts and Lithium batteries love voltages closer to 14 and a half volts. I wonder if Lithium batteries might be better?

I have the big Battle Born batteries in my van but it uses a special charger that is connected to my alternator.

I saw these smaller Battle Born batteries on their website:



They seem like a pretty good way to go - good for over 5000 cycles - what do you guys think?

I like the bundles that are offered. Can this new technology be mixed with older types like AGM? Do I have to replace my charger and batteries if I buy the new deep cycle battery type? I don’t have many hours on this stuff and wish to upgrade the deep cycle portion. Should I stick with AGM as it is much cheaper for a 100 amp hour battery?
