Ruko U11MINI/U11MINI 4K Intelligent Flight Battery

Overweight

I originally ordered this battery as a replacement for a defective battery I got with my U11mini 4k. Although afterwards I did reach out to Ruko customer service, and they were extremely helpful in fixing the problem. This battery does work with no issues, but for some reason it is significantly heavier than the original batteries, and the replacement I was sent. The difference is about 6-7g Not exactly sure what causes this as the battery looks the same and has the same mAh rating, but with this battery in the drone it pushes the weight over the 250g limit for an unregistered drone. For this reason it makes me nervous flying with this battery.

I got the batteries, and I am pleased with Ruko. Thank you very much.
