Jackery is using lifepo4 now, but their quality control is bottom barrel poor. I'd advise you avoid unless it's free.

I spoke with Jackery's customer service and tech support several times. I was depleting charge while leaving panels plugged in in full sunlight. They'd informed that the power feed can back flow to the panel, and that it is a known issue.

Honestly, I have a Jackery Home power 3600. The electronics have been buggy and unreliable. The battery can discharge itself through connected solar panels. It's a known issue. The inverter overheats due to its discharging. The panels desynch from the battery while charging regularly. The USB C output is entirely inconsistent. Sometimes delivering minimal charge and other times rapid charging. My little brother has an Eco Flow. He hasn't had issues with that system the same way that I have with the Junkery. Beware.
