It has been awsome compaired to the wore out lead acid starting batterys we had, I can go a week and a half with no sun before needing to charge it (only runs lighting and charges cell phones) the old batterys I had to charge every night to have lights, the sun doesn't do much in the winter here its been very cloudy this winter.
I never thought of that, planning on re insulating some of the walls anyway as the cold has shown where the original insulation had degraded over the years so will have some available left over for that!
Batteries surely have unique identifiers so the right one shows on screen when they're are several that need to be independently monitored. Some points come to mind: batteries have a rate at which they explode/burn/die from various causes. They're still in a roll-out and shakedown phase as car manufacturers all know. Did you know running 120v lights on a 12v system extends their life off the charts? There's a fire station in the States with a 120v (or 115 or whatever) light they never turned off. They celebrated its centenary some years back. It was down to 4w output if I recall. Have you thought of a fridge/freezer built into the north wall of your log cabin? It could even be walk-in year round in you dripped water and sprinkled saw dust over it all winter. It could be good till the winter after. If you went down a bit would help to make it a root cellar. I can think up projects till the cows come home. :)
I am still learning about these fancy lfp04 batterys, iv dealt with lead acid alot over the years. I stick to 12v lighting for now it's so much simpler but I do know of the power grid and their surging power especially at night.
What a great video, we were down the same road as you with the agm and car batteries, what a disappointing experience that was. I got into the lithium thing by building a battery from 18650 cells from laptops, definitely don’t recommend that but they worked great, they’re still in service now but on my ebike,lol. I can see you’re not comfortable with all the tech and it’s hard not to get dragged into it. The power thing is a slippery slope and where you are now is probably not where you will be in a couple years, all that being said, Victron makes great charge controllers, with or without Bluetooth, lol.
Thank you, I have heard of fokes building batterys from ebay cells? I think, definalty not my thing I hate electronics or soldering circuit boards. I know the true solar batterys usialy have a display on them or a communication with the charge controler to tell battery %. I find it easier to just stay away from power as much as we can so it's easier, more to break means more to fix or more that can break, usualy when you need it most. Things are coming along fast with battery storage teck, even if the manufacturer could do a simple light up display like a drill battery goes with the 4 bar light system, stupid simple but I guess most fokes like this fancy on your phone junk.
Nice! Yeah cold's not good. No charging below 0F and no discharging below -4F. The BMS should take care of all that though. Don't know what the manual might say about charging voltage but I wouldn't let the charger get above 14.2 volts. It can sit there for an hour or so for absorption. 14.6 is the max for a 12v battery but it'll degrade the battery sooner to charge it to full capacity but it can be charged to the limit. LFP also doesn't like to be left at full charge all the time either. 50% is their sweet spot but that doesn't mean you have to leave it there. Just use it and let it discharge. After you figure out your usage you can balance when you need to charge it and when to turn off the charging for a while to let it drain. All that just helps you get a good long life out of your battery which should certainly be well over ten years.
Thank you, yes the bms controls the heater and the discharge and what not. Manual said 14.2 max 14.6, that was mostly for normal fokes who don't understand as their lead acid chargers can get way over that if dead enough. Right now with the cold it barley charges anyway so it's up and down, editing videos helps balance as that's a long draw and should use about 20% of the charge so a good way to bounce it around. I have had to charge it a few times as the solar won't do a thing when it's not sunny, but I only charge it up to say 40% or something I never do full charge as that's running to long and costs fuel I just do enough to float it. Thank you, I am new to lfp, I have lithium in my cordless tools but the lfp is new as everyone I know that had solar has lead acid weather it be deep cycle batterys or a forklift battery.
I think you need 112 watts of charging to run the battery heater. I think the goal is to keep the battery warm before it goes into temp protection mode. Put the battery in a cooler to keep it warm. If that doesn't I think more solar or get a little USB heater pad to keep it warm. Its annoying but without 112 watts of charging the internal heater won't activate.
Thanks, I could not rember the power pull of the heater. Honestly we have no sun lately so it has not done a thing! No solar at all. Problem is it get cold over night like everything, water freezes in the kettle and everything. What I have been doing is if we get any solar it to run the generator for a few minutes to heat the battery and then the solar will take over from there once the battery is above 5°C that's once a week or so the sun actualy appears though. This winter has been very cloudy compared to normal cloud but no snow or not much compared to normal.
Do you mean from the panel to the battery bank or from battery to load? The wire from the panel to battery is oem by the manufacturer of the solar panel, from the battery to load is factory to the rv trailer. I have not changed any wires just used what was provided to me by the factory.
I think most of the wiring is 12 guage, the solar panel is only 100 W so under 9 Amp at full capacity, the lights are all led and if we have every single one on its somewhere under 3 Amp total.
You also need to take into consideration the age of the camper and making sure none of the wiring has been chewed by mice. Just want you to be safe for you and your family.
Thank you, yes it's an 89 or 90 I forget. It's been like this for I think 3 or 4 years I forget, we ripped rhe inverter out when we bought the trailer in preparation for moving it here. That's also why I was using the smallest Fuse possible as a 3 or 5 amp is nothing and could easily pop if anything every happened. We don't use the 120v side so unsure on that, we just have a small clamp on inverter for any 120ac things. Thank you for the concern, it's deffinatly a concern of ours as well and we were deffinalty skidish at first to even test the wiring.
Do you mean what we call a forklift battery? I know lots of fokes that use old forklift batterys for solar and that was my thoughts too, I like lead acid where one can simply know the charge level by the voltage.
It sure has been, the lifep04 batterys are nice small packaging and alot of power, a lead acid bank would be huge compared for the same energy. Thought they also have some down sides in my opinion.

Looks great. Hope it keeps everything running for you guys!

You should insulate the little cubby hole where you put the battery with the styrofoam that came with the battery.

With solar they recommended you use 10 gauge wire

Just be careful.👍

GREAT SHOW
Thank you very much!
Refurbishing two 510ah traction battery (FLA) - one is powering our 50amp RV right now. I am still not sure about lithium just yet.
Do you mean what we call a forklift battery? I know lots of fokes that use old forklift batterys for solar and that was my thoughts too, I like lead acid where one can simply know the charge level by the voltage.
Nice upgrade!!
Thank you, it sure has made a world of difference over the old junk batterys!
@offgridandunorganized I bet it has,so nice..
It sure has been, the lifep04 batterys are nice small packaging and alot of power, a lead acid bank would be huge compared for the same energy. Thought they also have some down sides in my opinion.
@offgridandunorganized Good to know.
