One of the MOST important things to know about an LFP battery before you purchase it.....does it have built in protection to keep it from trying to charge the battery(s) if the air temperature is 32° F or lower. In other words, a low temperature cutoff. Many of them do have that protection, but some of the cheaper made batteries do not. Trying to charge a LFP battery in 32° F or lower will damage the cells inside the battery and there is likely no going back.
I have never really looked too much at the plug and play LFP batteries because I'm building a battery out of 4 cells and making sure I have protections for it in case of cold weather. I'm sure others will be along to offer more advice, or maybe recommend a specific brand for you.
