Lithium battery with heater

Some people are going to say prismatic batteries are better, but for vehicle use I prefer cylindrical cells due to tolerance for a small level of abuse.

That said I have no idea about that either, but they look to be pretty standard generic prismatic cell battery. Probably no better or worse than any of the other generic models. All the cells for all LiFePO4 batteries are made by a few companies, so its not the cells I worry about, more the BMS and quality of interconnections, etc.

I would be more likely to try prismatic cells in a more controlled environment like a house than a vehicle.
