DIY battery module for 4DRC 4D-V2 nano-size quadcopter.

Flying Bear

Flying Bear Ghost 5

I used PLA for a test print, but it seems to be definitely not the best choice for a stuff like this

• 1S LiPo battery - 1 pcs
• Battery connector - 1 pcs

Original battery is 1S 300mAh QL852025,

n/a in my country,
so I used 702025 300mAh as a substitution - I recon it doesn't make sense while the battery doesn't exceed the measurements of 7x20x25 mm.

At AliExpress a 2pcs lot costs something about 3 USD.

This connector type has no particular definition or brand etc,
so it seems there is only one trustworthy method to find it at AliExpress - by using a search phrase like "10pcs 3/4/5/6/7/8Pin laptop battery connector female".
Use the image search in case of trouble.

The connector leads (just 2 of them - left and right ones) has to be soldered to the battery,

In the original case the connector soldered right to a small pcb - that would be extremely complicated to reproduce, so I decided to glue the connector right into the the case - 4 additional support surfaces were added to achieve that.

10pcs lot costs about 3 USD.
