    Small Boat BMS/LFP with backup

    See this post for some price and feature comparisons, REC Active BMS + CerboGX + Touch50 vs TAO BMS + TAO Monitor. Also Phillipe (TAO BMS) answered all my questions about TAO BMS use in this diagram, and I believe it could be substituted quite easily. See his Post #2 in his forum, and his...

    BMS design for boats

    I like the TAO BMS design, it is called a "Complete Energy Management System" and it could be used the the Small Boat BMS/LFP with Backup, quite easily. You would not need the CerboGX or Color50 as it has excellent instrumentation. See Phillipe's Post #2 response to my questions and following...

    BMS design for boats

    Thought you'd be interested in this link, even though it parallels LFP with FLA, due to the modular aspect. https://www.bos-ag.com/products/le300/

    12v BMS design. What would you like to see

    30w x 3.41 w/btu/h = 102.3 btu/hr not that much really.

    Small Boat BMS/LFP with backup

    I've written Phillipe at TAO BMS and he has kindly responded in detailed manner which answers many of my questions about use of the TAO BMS. It appears there is another iteration which may remove the need for CerboGX and ColorGX, while still providing a status display and operation through a...

    Small Boat BMS/LFP with backup

    I agree, but it is a small boat! Perhaps a cabinet or shelf would be better?

    Small Boat BMS/LFP with backup

    For access from the top, I could provide an access panel under the cushions, that is lapped or dadoed and rabbited which might be the best approach. The cushion would have to be set to the side (glad we got 3 cushions!). On the port side we would need two access panels (one smaller so it can be...

    Small Boat BMS/LFP with backup

    Thanks for the description and photo it is helpful to visualize what is needed. Unfortunately our layout is the classic port and starboard cockpit lockers with no pilot berth. I am uncomfortable putting the LFP and BMS in those lockers due to potential to get wet if innudated from the stern...

    Small Boat BMS/LFP with backup

    EVE LF100 $75-85 Stacked 3 high for 300ah it would be a box about 8" x 10" x 18" high Relays, BMS, disconnect switches and 1-0ff-2 switch under a lid in the top. Sides would have some vents for air flow. Each stack accessible from a door in the front perhaps with a slide out tray? The box...

    BMS design for boats

    No kidding! I was following the development too and thought Al should also make a BMS at the time. Then I saw one of the Gen3 for sale and actually purchased it for very little. ..Still using a Balmar ARS-5 though. Very interesting about the regulator work.

    Small Boat BMS/LFP with backup

    Cool custom boards with Lin! Thanks for the ELCI suggestion, big saver! I think I would fit this in the port cockpit locker using a IP67 waterproof box with a WP door. WAY LATER: See Nick's good suggestions in CF...

    BMS design for boats

    Very Nice. Wish I understood it all. I was going to send you a new TI Lin based Alternator Regulator microchip link, but I deleted it and can't find it in the recycle bin. Maybe this was it, but I thought it was TI.

    Small Boat BMS/LFP with backup

    Now I am liking the idea of a keyed switch. I should estimate those costs too. I need to add ELCI and new shore connection as we have no AC panel, then I could connect the two 120vac plugs, refrig and domestic hot water heater, but we would never use it because we are on a mooring. However we...
