another nudge toward Battleborn, albeit a significant one. Thank you.

Im following your channel. And it would be great to see some catamaran solutions with high power alternators and 48V solutions not disregard ce conformity. Will you expand to Europe? France could be a interesting market

Great video

Thank you Connor and Battle Born for this information.

Outstanding Video Connor, thank you.

Excellent video. Thank you very much for making these.

You're welcome! Glad it was helpful!

So you recommend Kead acid battery for starting engine, starting generator, windlass (mayve also winch?? I guess toilet macerator no need??), and put all the rest to Lifepo4, correct? Then the alternator should charge the Lifepo4 with a DC-DC charger, and then other DC-DC charger to charge from Lifepo4 the Lead acid batteries?

I was hoping this was goi g to make it look easy to convert my trawler to lithium

Very informative, thank you. Can you provide a bit more detail on the case ground. I am working on installing a LiFePo system on my sailboat and cannot get a clear answer on where to terminate the case ground wire. Ultimately the DC system is grounded to the engine with the negative cables from the house and starter banks and the AC system is also grounded to the engine via shore power and a galvanic isolator. Your tutorial mentioned grounding to the grounding buss; however, because I am using a Lynx Distributer with a dedicated ground to the engine block, can I just connect my case ground to the grounding terminal on the Lynx Distributer?

Hey it’s Conor from the video. So, off the bat, always consult a marine technician for your exact install specifics. But it sounds like you are on the right track. I like a dedicated grounding bus, where I can keep track of all of my ground connections: such as case grounds, DC negative connection, AC ground (ship side of shore breaker), perhaps prop shaft electrode, and maybe rigging lightning ground. I think the ground on the Lynx would work well to connect to a ground bus, to collect all grounds. But if you have just one, it could work. As you lay out your system, keep in mind you don’t want a ground conductor to be carrying current accidentally (in parallel with neutral). Sometimes when things get grounded the ground can be accidentally carrying some neutral loads back to DC negative, so just make sure there are bigger and more direct DC negative routes for that power. Safe Sailing!
