I am not affiliated with these companies. Thought I'd share as it seems like there are a few Canucks on this forum.
Marine Solutions Inc - Saw their goods at the boat show and bought a solar kit from them. This looks pretty robust - $2400CAD for 3kwh or 240AH. Seems like a nice option for a...
I picked up this combo (high-leverage cutter and cable lug crimper). There is a cheaper crimper only option in stock now (that wasn't when I bought) I had read the reviews and noted that the crimper was not always sized correctly. My short assessment after wiring my boat. I used 6AWG to...
So I've picked up a set of the 280Ah cells a solar charge controller and panels and the chargery BMS. Next up are a set of tools and meters but a question for the more experienced:
Would you recommend I also pick up a set of lower AH cells to "learn" on? I want to wire them together on a...
Forgive me if this is too much of a noob question but I had a question about charging these diy lithium batteries. I plan on having a solar with separate MPPT charge controller but will also have the bank hooked up to a shore power 40A charger on my boat. Now the charger has a setting for...
Wondering for the sailors who have installed LiFePO4 housebanks on their boats. Do you leave your boat plugged into shorepower and the charger on (has float and absorbtion profiles but our batteries are pretty much back to full by the time we return to dock
With LA I always left the boat on...
I think I understand the purposes of each (BMS - Low voltage disconnect would disconnect if a cell voltage drops below a certain value) and Victron's Smart Battery Protect would disconnect the loads (no inverted in my setup) if the battery voltage drops below a threshold.
Would the SBP and BMS...
In the northern hemisphere, it's time to prep the boat for haulout and a winter. I am going to take my LiFePO4 house battery off the boat over the winter (would like to do some testing so see how the capacity has changed over the course of one season. I will put my old AGMs back on board and...
I can't seem to find ring connectors that fit the gauge of wire (24AWG) that came with my BMS (the JBDXXXX) the Ancor connectors only work to 22 AWG - what do people use for connecting their wires to their battery terminals? I tried a robotics and maker shop and they did not have anything like...
I have a Victron BMV 712 battery monitor and really like it - TBH if i redid things i would just but the smart shunt they have now as I rarely use the BMV head to check my batteries. But thinking about LFP, I would be adding a BMS which operates somewhat like shunt that can shut things off. as...
I picked up a blue seas 7238 30A breaker for my PV shutoff and also picked up a “small” breaker box off aliexpress but now realize the breaker cannot be mounted on a din rail. What do people use?
What are people using for panel isolation (between charge controller and your panels) I've seed the DIN rail mounted breakers but then I'd have to get an enclosure and it starts to take up space in my limited battery / electrical garage on my sailboat. The wiring will come down, through a deck...
Does anyone have experience with these panels? Amazon seems to have the best deal for these with shipping built in but wondering how reliable these panels are for the cost. Would I be better off picking up two 100W semi flexibles with more of a warranty for about the same price?
I finally got around to ordering a proper case for my 4x 280AH cells. They did not seem to have expanded however when i fit them into the battery case kit, i can see there has been expansion. (note the bottom fits into the case bottom, however the top will not fit due to the cell expansion. Is...
Looking for opinions -
Current Config:
AGM start, AGM House
Both combined through Isolator to Alternator; Individual wiring from Shore power charging (40A), set to AGM profile
Proposed:
AGM Start, LFP (280AH) House
Alternator to charge Start only
Start wired to Orion TR DC to DC Charger to...
I am looking to construct a 300Ah battery pack for our sailboat house system - For battery box size considerations I think 8 cells is the limit at this time, unless I build a new box. I am still dubious on the number of cycles these cells will produce and what the failure rate of individual...
So I wired my boat with the solar wire. I noted that one wire had a positive (male) connector and the other a female connector. I assumed that meant it was the positive wire so I put the disconnect on that wire. I now realize the positive wire coming off the panel is also a male connector.
Is...
My temperature sensor was damaged and now works intermittantly. I understand it is an NTC 10k Thermistor and the connector is a JST GH 1.25mm pitch connector. I am having a very tough time locating a replacement (either on Aliexpress - to arrive in Jul) or the components to reassemble an...
I returned to my boat after being away for a week or two and the 12v system cut out - when I checked the BMV it read 12.5V but SOC was in the 90% range (AH) the LiFePO4 bank is about 5 years old as is the 220W of solar so something is starting to fail.
Checked the BMS and see that the cells...
Is it just me (or that I am in Canada) but have Semi-flexible panel prices jumped substantially since the fall of 2019? I am looking at a 100W Sunpower semi-flexible and at our Boat Show, they are asking for $299CAD a panel ($229USD) - The off-brands (renogy, Eco-worthy seem to have increased...
So when people build their banks with large LFP cells which come with these relatively small M4 terminal screws, what is the thinking on terminals? for instance my existing battery cables (to charger, breaker, load) are 2 gauge or some even bigger and have the clamp terminals on them. Am I to...
Hi - I have a sailboat that is hauled out for the winter and the solar panels are disconnected and stored. I realize the solar wire (not plugged) has exposed the contacts to corrosion.
Is there a way to test for corrosion to see if this is why the panel (sunpower semiflexible 110W - 4 years...
I have an odd situation with my JBD BMS (I think this is the cause).
The BMS seems to activate when I connect the cell monitoring harness (I measure 13.5V between the battery terminals, and at the B- and the C-. But when I connect the battery to the circuit, I do not get any voltage or...
Hello. I have a Victron BMV 712 measuring the usage and charging off my 4 cell 280AH LiFePO4 battery. For the past 24 hours, I have been getting a high voltage warning every time I go into the BMV app (the high voltage alarm is set for 15V but the BMV is only reporting 13.68V; the Solar is...
