I'm shopping for SVOLT 196Ah cells and found NogiBattery which seems to (1) sell them and (2) have nice accessories for them. I also contacted evlithium.com . I've never worked with neither but NogiBattery is also offering a partial module assembly service where they weld busbars into a...

I'm looking for off-the-shelf 48V LFP batteries that fit very specific dimensions: No longer than 100cm No wider than 20cm No taller than 35cm My application is quite weight sensitive, so high Wh/kg is important. Finally, CAN communication is highly desirable but not strictly necessary (for...

The installation manual explains how much air flow the genset needs when in an enclosure, it's just a matter of engineering so that those numbers are met. Humidity, what about it? There's humidity everywhere and aircooled gensets work just fine. Salt is the problem, and an air filter will...

Small size, light weight, direct DC with CAN communication with Victron. These generators are game changers in my opinion. The air-cooled would require some thinking, but their manual seems to suggest it's not unworkable. On a boat I think the salt-air could be dealt with using a large air...

For my dinghy I'm taking off my ePropulsion E80 (4kWh) and replacing it with a DIY pack of 2.9kWh using NMC (16p14s LG MJ1). It's much lighter, and I don't need the 4kWh of range of the heavy E80. I put my DIY pack in a Seahorse 720 waterproof box, and on top of being waterproof and easy to...

I have an electric sailboat catamaran, 35ft, with 2x6kW pods from ePropulsion. I don't understand why you need two batteries on a 42ft boat split between bow and stern. Your suggested battery pack is wayyyy too big, especially if you have a diesel onboard as main propulsion. If I were you I...

Hi folks! I've built a 48V pack made of 16x CATL 280Ah cells, with a REC Q BMS. The cells were purchased with Jenny Wu from DocanTech in July. The purpose of the pack is to power 2x6kW outboards to propel my boat. However in low-power tests (3kW) I'm noticing that the cells are showing an...

Right I saw that since posting. I'm trying to find the most efficient panels that'll fit a 65 by 50inch surface.

Hi folks, I'm looking to buy a few (4 or 6) high efficiency rigid mono panels, and get the absolute most power I can for a given area (surface area is limited). Something using SunPower/Maxeon cells, or LGs, and willing to pay extra for the best. It seems like there's no places where I can buy...

I've got a box full of Maxeon cells and I'm heading this way too for a custom fit on my sailboat's roach roof. However the big question I have is how to encapsulate them. Anyone has any insight?

Good idea, fired them an email. I saw their stuff at a boat show at least once or twice.

I'm looking at two (2) outboards, each between 6 and 10kW. At 48V that's between 125 and 210A. AWG 2 or AWG 3/0 will do, but 4/0 will help with voltage drop. So on that side, it's not impossible. Realistically, the bank should be able to run at max power (20kW) for 30min, and it's very rare...

I'm super curious about hybrid propulsion (electric drive, fossil fuel generator for range extension). I have a Seawind 1000 XL2 powered by 2x Yamaha 9.9 high thrust variants. I'm searching around to see if any outboard would fit there. In addition, I'm planning for the propulsion battery bank...

I just realized Hatteras 53 are powerboats, that changes things. I'm on a sailboat. You probably have a much larger power budget than I do, and more unshaded surfaces to put solar.

Yeah I'm 100% not suggesting that you rewire your boat :p. I wouldn't do it. For heating/cooling, I think unless you have a ton of solar and a massive battery bank (for overnight), you're better off using a diesel heater or run the generator. My 38ft boat takes ~800W continuous to heat, and my...

I assume you mean that your current boat is all 12V? Same for me, and here's what I did: - Keep 12V as is, keep only one battery from the legacy AGM house bank (for starting the diesel). I could probably change this to a much smaller one. - Put a 24V to 12V battery charger (Victron Orion TR...

What's your budget, and what sort of cells are you planning to use?

Yup I'm looking at NMC, not LFP, fir this application.

The existing 32V battery bank will also operate within a range of voltage: as such, it can probably be assumed that the 12S LFP setup should work fine, voltage-wise. But I'd still go for a more standard voltage house bank. Smaller wires at 32V is cool but the small wires matter more with regard...

That's perfect, I wonder how I didn't see this one! Thanks a lot!

I'm search for a small-ish MPPT controllers that can charge a 48V (up to 58.8V) battery. In the Victron line-up, I've seen the BlueSolar 150/35 that's about 250$, and then it goes to their SmartSolar MPPT 150/45 and above range, which is 450$, and frankly massive. Is there such a thing as a...

Hey folks, I'm eyeing this BMS (the 150A separate port) for a 48V, >6kWh bank that I'm planning to build. I was wondering if any of you have used them, and if so, what your experience has been? It's for a 125A load, is the rated 150A going to be enough, or should I assume that they inflated...

To connect your alternators to the LFP batteries, you'll need to be careful. You need something like the Balmar external regulators to prevent the alternators from burning up. Better keep the alternator disconnected if you don't want to change/upgrade them (it's at least 1000$ a pop), or use a...

I'd use a DC converter if you don't want to change all the wiring/legacy devices, and put a 12 or 24V LiFePO4 bank/system. It's really hard to find any marine hardware above 24V. The water heater on my boat uses ~1500W when it turns on, it's probably common. With a 915W solar array, I get about...
