Neverland 3S 18650 lithium FPV goggle battery box with capacity checker for Skyzone Fatshark

thingiverse

You can store up to two-and-a-half times more power than a Fatshark lipo. Three Lithium 18650 cells are needed. Many of the marked "good" cells claim to hold over 4000mAh, but the truth is there are no 18650 cells that can store more than 4000mAh. Google for a reputable dealer who offers these cells: Samsung INR18650-35E and LG INR18650MJ1 - 3500mAh. Sanyo/Panasonic NCR18650GA is another option. Every cell will cost you at least six USD or EURO. If they are cheaper than five USD/EURO, they are probably fake.
