I have this aluminum hanging around. The LiFePO4 battery and box is already built. These strips will serve I am fairly sure - one on either side of the battery bank. But we shall see.
Hello, I have not yet tried it, but interested as it is in my own province, if interested to watch a french youtube post even without listening to the french user he is showing the batterie's interior, I've submitted this same post to Will Prowse and only to him as he is always interested to compare different manufacturer quality, hoping this is not against Will's forum policy. link :Has anyone tried the new Volthium lithium batteries? They are made in Quebec Canada, and have low temp cut off, but also are self heating. Just wondering how well they are built.
Seriously why not just use fans like I did? Use the power your using already in your space to keep them at a comfortable temp 24/7? Unless your using them in a shed, which the battery heaters aren't such a bad idea..but then you'd have to worry about cooling too. Its so simpleI still like the zero voltage required controller for my battery heaters. The Honeywell T6031A1029 is very reliable , easy to install and uses no power to monitor or activate the heaters. Why add another energy eating control to you system when there is a battle proven control that has been used for generations. I found mine on Ebay for less than $40.

yeah but if you have them in storage and the heaters constantly run wouldn't this drain your batteries down? In that situation I'd just slap anderson connectors on each pack and bring them inside when not in use like I did until I went full time rv life. I even think the manufacturers who put heat pads into their batteries are dumb. You need to take care of these. All that does is make people think you can just set it and forget it which you cannot. Thats why they make bluetooth BMS now so you can see the stats in real time. Think about if you left the packs out at something like 0f and you werent there, those cells are not gonna be happy being drained all the way down and your not supposed to float charge these.I spent half what you did on my two thermostats. I get individual control over the heat for the two batteries. The watts required for the thermostats is negligible.
When I'm actively using my trailer, the thermostats and battery warmers are turned off. It's when the trailer is in storage that I have the warmers active.

I think you may be chasing a non-existent problem. My little digital thermostat only pulls about 80mA @ 24V when the heat isn't on. So a 280Ah pack could power the thing for 3500 hours, or about 146 days.I still like the zero voltage required controller for my battery heaters.

you might as well just do the xiaoxang BMS like I did with the low temp cutoff as well as high temp cutoff. I have the 4s 12v version on each of my packs. I got two more coming with my CATL cells(8 of em 280ah). Im gonna have over 1000ah after I add them beasties.Better add a couple more batteries! LOL!

I have a small 24 volt system with two 50 amp hour batteries. I built an insulated box with leftover 4" poly iso foil coated foam from a construction project with top lid. I use a Vivosun 6" x 8" reptile heat mat and digital thermostat combo from Amazon. It is an 8 watt 120 volt heater pad plugged into the inverter. I set it at 45 degrees and it works great even in the High Rockies at sub zero temps. Insulation is the key.If you are trying to use a lifepo4 battery in freezing cold temperatures, battle born just released a 12v heat pad for keeping the batteries warm without melting the case. This pad should work for any standard lifepo4 battery. Just slap it under your batteries and connect it to 12v and you are done.
I think it is over priced though. It can be found here: Click Here for battle born heater pad
If you cannot afford the battle born pad, you can use a septic tank heater pad. It works in the same way but may possibly melt your battery case if you are not careful. You can avoid this by adding some protection or a way to distribute the heat across your entire battery bank. I would personally put the batteries in a insulated container, then add a thin sheet of conductive material like sheet aluminum over the pad so that the heat it produces can warm up your entire battery bank.
