Mark - many thanks for posting that detailed background/reasoning! Your design process/decision tree all makes sense.
I'm guessing this is the Sterling device you mentioned?

Fascinating topic. As I try to...
Everyone - thanks for the advice!
My initial post above was just about adding an LFP battery as a house battery (only), turning what was a single AGM start+house boat into a start AGM + house LHP boat, but without battery combiner-type functionality for the reasons stated here. The crazy...
Agreed! The only connection between AGM and LHP4 batteries is the DC-DC Charger. There is no "1/2/all"-type battery combiner switch in the mix. Starting the engine is the sole domain of the AGM, which has a conventional on/off rotary battery switch.
Thank you! I was determined to learn just...
Thanks!
I did have the Permatrim/warranty question at the start with the mechanic, who is an authorized Suzuki dealer. He said that he would not consider it as a warranty-voiding modification, which I was appreciative/happy to hear.
BEHEMOTH was recently re-powered with a Suzuki DF50A.
I thought I'd share initial impressions and info, in case it helps someone else.
This new motor replaced a 2005 Honda BF50A which had become unreliable (due to carb issues that few mechanics could fix or wanted to take on).
The mechanic...
Hi folks - Hoping to share some ideas and also learn from the rest of you 😉
I have a C-Dory 16 Angler (BEHEMOTH), used mostly for cruising around and exploring here (Seattle / San Juans - day trips, 1-2 day overnights).
Currently, there's just one 100Ah AGM battery for the 50HP main and a...
Wow -
I'm so grateful for all of your advice, insight, and encouragement... and warmth.
Much appreciated, folks ;)
I may have some follow-up questions as we prepare, and I'll share photos also ;)
One step at a time!

Hi folks - I'm mostly new to boating, and the happy owner of a C-Dory 16 Angler.
My son and I have crabbed and day-tripped in/around Skagit Bay, including a 40 mile day trip to LaConner.
And now we're thinking about a more adventurous 2 day trip out to Friday Harbor, launching at Anacortes...
Hi Tom -
I like the radio a lot, but you should note that I'm still new to boating, and that I've only had the radio on the water a few times (with boat under it ;).
Some specifics:
- It fits pretty well (for me) below and to the right of the wheel in my C-Dory 16. (There's a photo showing...
I thought I'd share my experience getting a Garmin chart plotter (ECHOMAP Plus 64cv) and Standard Horizon VHF (Standard Horizon GX2400) to talk to each other via NMEA, in the hopes it might save someone else some time.
I started by networking the two devices with a NMEA 2000 backbone kit from...
Hi Bob - thanks for your comments/questions! Much appreciated.
My answers are below; feedback welcome:
I went back and forth on this, and in the end decided that I wanted to be able to use the battery switch to cut power to everything in the boat. This is how it had been wired initially, and...
Here's an update on this project, in case the info might prove helpful to others considering something similar.
Cuddy:
- Battery in bolt-down frame (West Martine #17549718)
- 150A fuse in holder (Blue Sea MEGA® / AMG® Safety Fuse Block)
Stern:
- Distribution Stud Module (dual) (BEP 702-2S)

Marco - thanks very much for the info & advice!
I thought I'd share some additional info, in case it helps other folks.
Question #1 - Regarding Gauge: I emailed Honda support... and they answered within an hour (!):
- Honda engines come with battery cables, a BF50A model would have cables...
