Review on 🔌 ULTRAPOWER 4Amp 12.8V-14.4V Lipo LifePO4 Battery Charger: Intelligent 4-Stage Maintenance Trickle Charger for Cars, Motorcycles, Lawn Mowers, Toy Cars, and Golf Carts by Michael Luna

I have this to charge my lifepo4 batteries when not connected to a solar array. Well, it will work, but it thinks the battery is fully charged when it isn't. I have to unplug the charger and restart and it will charge for a few more hours and then I have to do it again. Eventually they will charge fully, but since they have to be cycled off and back on to finish charging, it's very slow. I would not recommend that. I only set it up when it was too late to return it.
