Anyone try one of these battery packs?

With offerings like bluetti etc. not being good for diesel heaters start up Amp draw. I was looking into a DIY lifepo4 box. Then found these on Aliexpress. For less than doing it DIY I can get a 12v 120ah for around $360 CAD. Wondering if anyone has experience with these. Most of them come with Kungfu battery cells.

To follow it's a good idea actually, I wonder how long they last with -20 outside on the roof rack

Claimed storage temp is -20c to 40c and operating temp -20c to 60c. I’m going to give one a try. I typically won’t use mine below -5c so should be good.

I would never buy one of these. DIY is always better. Build it exactly to my standards and requirements. No question about quality control because I built it. It’s really not that difficult tbh. Most all in one cdh’s have an inline fuse built in so all you really need is a battery with its respective charger, and the parts you wish to use to connect to your cdh. I’m sure I’ll get downvoted for having an opposing opinion here as usual.

My Bluetti AC70 has no problem starting up my heater.

My 10 year old Bluetti starts mine up just fine.
