[QUOTE="thill, post: 508841, member: 4972"] I set up a system like this for a customer. A Blue Seas switch on the boat and an on/off switch on the LiFeP04. He is to ONLY turn on the lithium battery when sitting, for extended periods, and to turn it off before starting the engine again. The Blue Seas prevents the lithium from "charging" the starting battery, and the switch prevents the lithium from taking the hit when he starts his engine. In MY boat, I just have a separate circuit from my 50AH lithium that goes straight to my Livescope system. I can switch them over to the regular batteries by moving a terminal, if that is ever needed. I have a dedicated LiFeP04 charger that I can plug in as needed. Since LiFeP04 batteries like to be stored at 30-50#, I don't worry about charging them until the night before a trip. The livescope doesn't use much battery in a day, so it may not get charged for a couple of trips. [/QUOTE]
