Eachine Assassin 180 battery case adapter

thingiverse

Proprietary connectors are always a major drawback, especially when you break a couple of Eachine Assassin 180 racing drones and have no spare batteries to use with them, which is unfortunate since theirs are quite decent. This case/adapter makes it easy to utilize the batteries as they were intended: simply slide in and lock. To create this adapter, I used nickel strips, commonly employed for DIY battery packs, but any metal sheet that can reach the contacts inside the battery's plastic casing and carry sufficient amps will do. The three contact points on each side are where you can draw current; the two central ones serve other purposes, possibly monitoring temperature. I opted to use only four out of six contacts (three positive, three negative) since my goal is to absorb no more than 20 amps (with a maximum of 25 amps), and the original configuration with six connectors was designed to handle over 50 amps. The more connections you can utilize, the better. Please note that we're discussing hazardous Li-Po batteries, which may be damaged due to crashes; therefore, I disclaim any responsibility for potential issues arising from building this adapter, particularly if you choose not to exercise caution and work with these batteries without proper knowledge. Despite what the photos suggest, the attached solid file is version 2, featuring two holes on each side that can accommodate standard M3 Allen screw heads. If you want to establish a mechanical connection on this side as well, use a small amount of glue; otherwise, disregard it.
