WLtoy WL916 upgrade battery.
The lipo of 3800mAh & 3850mAh are much bigger than others, you need to cut the original battery tray, in order to fit in those battery. Modification is required, otherwise you can't close the cover.
If you don't know how to modify, please purchase only 1800mAh, 2200mAh and 3600mAh instead. Those 3 capacities can fit enough without cutting.
