Very happy with my EarthX LiFePO4. It has built in overcharge/undercharge circuitry so you can use any charger with it.
That said, it never has needed a charger. Expensive yes, but light and powerful. Supposedly will last at least twice as long as a conventional battery. I'm two years in, very happy with this battery.
