I personally recommend avoiding 18650 lion batteries that state a capacity of over 4,000 mAh. Some manufacturers even state 6800 mAh and more on their products, which far exceeds the parameters of li ion batteries. Well, the truth is that their capacity is at best 1200 mAh. From my experience, batteries with a capacity of 4100 to 12000 mAh have at best 1200 mAh, but more or less have around 350-600 mAh. These batteries weigh around 22-28 grams. Under a higher load, they start to collapse, or the voltage on the battery starts to drop sharply. Durability is questionable. And above all, the batteries must weigh 44 grams or more (eg 2600-3400 mAh have 45-49g) Contact email: 2626@centrum.sk Phone: 0949369637
