OEM batteries are expensive, and I am just an amateur photographer so I decided to try this 3-pack from K&G Concept. The kit comes with 3 LP-E6NH batteries, a multi-battery charger and a USB-C cable. I have a Canon 7D Mark II, and these batteries are compatible with it.

The batteries are 7.4V and 2250 mAh. They are identical in shape and size to the standard, brand name batteries. They fit my camera perfectly, without any snagging or play. The charger is lightweight, and can charge all 3 batteries simultaneously. There is a convenient LCD display that shows the status of the batteries as they are charging. Charging takes a few hours though, using a standard USB-C cable and adapter.

I tested all 3 batteries with my camera, using the flash and also taking fast pictures in raw and jpg. The camera had no issues or hiccups whatsoever. No error codes or power offs. The batteries perform identically to the original batteries. Time will tell how many pictures can be taken on a single charge but even after a few dozen pictures, they are all holding their charge. This kit is a great value for those amateur photographers that need replacement batteries at affordable prices.
