LifePO4 battery for flats skiff

Purchased a 120ah Lithium Iron Phosphate battery from Custom Marine for use with a Hells Bay Marquesa 18' Flats skiff with power pole and trolling motor. Highly recommend. Prior I had two led acid batteries: one for start and second for trolling motor. With LifePO4 I only use one battery for start, trolling motor etc. Advantages:
- simple wiring with everything on one battery for all electrical functions
- charging the battery with the outboard's alternator
- battery lasts a very long time while on the trolling motor by having a battery that can be used well below 50% state of charge (unlike lead acid)
- battery doesn't run down while the boat is not of use. It holds its state of charge for very long periods
- the ability to check the battery with the bluetooth app on my phone.

This battery and setup is a game changer for bass boats and saltwater flats skiffs. Highly recommend these batteries and Custom Marine. Tom has been wonderful to work with. Prompt, intelligent service.
