PROS
-Extremely compact size very lightweight.
-15 amp continuous draw big reason I bought these batteries so they can both be used on cameras and lights and are airplane travel friendly.
- plenty of ports and the info screen are very helpful for plenty of different battery setups.
- quality for the price is also pretty good. They seem solidly constructed and well laid out.
CONS
-I wish the display had a non backlit mode so you could constantly see the info without having to press the side button. Which if you have larger hands can some times be tricky to hit.
-They seem to bleed power a little more quickly when shelved and fully charged than other v mount batteries I've used in the past. You will want to make sure you are topping them off before you intend to use them It's not something you can charge and leave on the shelf for a few weeks without losing 10% to 20% of the juice in the battery.
OVERALL
Amazing battery for the price especially if you want a versatile travel battery with an info screen. The amount of power, ports, and the compact size/weight of the battery are also unbeatable for the price. The only minor issue is the increased battery bleed but I'm totally willing to overlook that because of all the check marks this battery hits.
