Power Queen 14.6V 20A LiFePO4 Battery Charger, 2-Stage Automatic Smart Battery Charger and Maintenance, LiFePO4 Lithium Batteries Charger, Suitable for 12V (12.8V) Lipo Lithium Iron Phosphate Battery

So far so good. Seems solid operationally. Not a bunch of superfluous screens and buttons to cause failures. Just basic controls. Seems well build with a metal case and minimal plastic. It was priced competitively. It came with a 3 year warranty which was better than others in this class that had 90 to 365 day warranties.

Works well with PQ 50ah battery. I agree with some others that it is noisy but that doesn’t bother me.

Charges battery very quickly. Quality product.

Works great. Just what I needed to bring my dead battery back to life!

Works ok just slow to charge. I would buy a bigger one next time

Charged my LiFePO battery at 19.9 amps according to the battery BMS readout on Bluetooth. Nothing to complain about for a 20amp charger. Fan is a little loud, but it is a small unit to be delivering 280 watts for hours continuously. Very happy with the purchase, better than I expected.

Seems to work fine. Charges my 100amp hrs. Batteries in just a few hours.

Works great just as advertised. The only drawback it doesn't come with battery post clamps. But not a game changer. Kept the price down by not including.
