Reasonable charge speed from 'flat', good capacity for a lighter weight battery.
My intention is to use the K&F Concept NP-F550 Battery and Charger Kit to provide a higher capacity battery for my camera monitor, without adding any noticeable weight increase to the whole package.
But, for fun, I connected both batteries to one of my 45w LED panel lights, and ran it at 30% output to see how long these small batteries might last, slightly under 2 hours later, I found out!
The batteries were slightly warm from that load, but charged up normally afterward, so no damage done. They should run my monitor for over 2 hours continuous, so the pair, with the original battery, should set me up for my next weekend away with camera quite nicely.
The charger unit doesn't show the state of charge of the batteries, showing a red LED when charging, changing to a green one when charging is complete. It is not a particularly fast charger, so several hours are needed to go from exhausted to full.
No complaints from me, they will power my monitor beautifully, and I know I can drive a LED panel, at a push, if needed.
