Converting house batteries to Lithium in Cutwater 242

[Dmullen]

We are going to change our house batteries to Lithium in our 2018 Cutwater 24 with a 300 Yamaha. We have the Abso 20 amp charger which will need to be reprogramed. The 2000 watt inverter is OK. The challenge is the alternator. The engine battery and the thruster battery will remain as they are and I'm not entirely sure what we need to do to set this up. Has anyone converted their 24 with the outboard to LiFePO4 and can give us some advice? thanks.

Check out my post on the Ranger Tug 23. viewtopic.php?p=123215#p123215. Also, if you do a search for "Lithium" in the search bar you will see a number of other recent posts. Our boats are very similar but you will have larger outboard.

The outboard option is a little different than the inboard options because the inboard will have an alternator while Yamaha and Suzuki outboards have Stators instead. The installation is relatively simple but get help if you are not sure. Battle Born were super helpful in fine tuning my set up.

Good luck - it was a big improvement for us.
