Ionic Lithium 12V Group 31 3000 CA LiFePO4 Heavy Duty Battery

No I didn't but you have to understand that the BMS of a properly engineered battery will cut the battery when the temp is too low, those little jump boxes are an exception, they won't destroy a truck with a fire like a G31 LiFePo will.

The one reason that I like the Maxwell starting module is the temp range is wide.

 

This fella from Youtube has put a few Chine Sium Mewyah batteries in a Cascadia in the starting bank. Don't know his warranty policy after a year...

He's pretty knowledgeable about DPF repairs.

 

The cold temperature performance would concern me since it gets cold AF up here.

Will these batteries burst into flame if damaged/punctured? I could see losing a truck, trailer and load from a minor collision.

 

I don't know considering where I run I wouldn't try them, I have Northstar AGM's that weren't cheap like $400 a battery, that have like a 4 year warranty no questions asked no prorated bs, I had to use the warranty after about 1.5 or so years and they replaced them no questions asked, I think I had one go bad right off the bat and didn't realize it, because it was a little hard starting after the first couple months. Then right after that replaced the alternator and haven't had an issue since, I also check the connections after every week and make sure there isn't any corrosion. They have lasted now 2.5 years with absolutely no issues and I can let the truck sit for a week and start it with no issues, so considering what it was like with regular batteries I think the added cost is a win. If the lithium batteries improve their cold weather performance they will be going in next until then I will run AGM's

 

I would feel more comfortable with a dedicated separate emergency start setup like Maxwell or similar than having all my eggs in one basket with these as my main truck batteries and APU/AC batteries. Maybe 2 of these and a start module? This depends on where you run too. I don't like the idea of lithiums out in extreme weather. Still need some time other delta before I would be comfortable with it.

Also, just my opinion, if doing an APU I like having a separate battery bank. This is more of a comment on the video I guess. That guy knows his stuff but no way I'd want to run a battery AC off the chassis batteries. I like having a separate master shutoff between chassis and my lithiums. I do have cheap lithiums but so do a million other people in campers, etc. these days and we're not reading about fires or other trouble in the news or in the reviews.

As far as that under bunk AC I love it but I would run a duct up the wall and spit it out near the roof. No matter how powerful the vents are at the floor truck sleeper cabs gather hot air up high worse than anything. My Tripac was horrible with the one big vent down low until I fed a duct in to the factory upstairs sleeper bunk vent. Then it was just ok.
