<font size=6 color="orange" face="Times New Roman">What it is?</font> <p align="justify"><font size=3 color="black"> It is a simple converter allowing to use popular 18650 batteries tester (like Opus BT-C3100) to test other lithium batteries like Lithium polymer ones. This is more neat way of testing cells with wires instead of terminals and avoids danger of disconnection during testing.</font></p> <br> <font size=6 color="orange" face="Times New Roman">Parts</font> <p align="justify"><font size=3 color="black">You will need:</font> <blockquote> -9cm of any nickel plate, i used 8mm wide and 0.2mm thick<br> -terminal block, probably this *elevator* type one will be better then the one I used<br> -soldering iron recommended<br> </p> </blockquote> <br> <font size=6 color="orange" face="Times New Roman">Assembly</font> <p align="justify"><font size=3 color="black">Total length of one nickel plate: 7+12+32+4mm = 55mm, since you need two such pieces: 110mm = 11cm. You may use these dimensions to prebend nickel plate before and make your life easier.<br> Insert nickel plate to the top hole which has end. Then bend it over the terminal and mark where it should be again bended to get back inside the part. After that, take it all nickel plate out, bend in marked place, cut the longer leg so that it will reach the terminal block and mount it for the last time. To connect a plate with terminal block I used soldering, just prebend the terminal legs and plate to touch each other firmly, add solder to the tip of the iron and jam tip inside hoping that you will make a connection - may be tricky and you may melt some plastic but no big deal... I am looking at all of you perfectionists :) </font></p> <br> <font size=6 color="orange" face="Times New Roman">Updates</font> <blockquote> <font size=3 color="black"><u><b>13/04/2021</b></u><br></font> initial release</blockquote><br> <br> <font size=6 color="orange" face="Times New Roman">Sources</font> <blockquote> -Terminal block:<br> <a href="https://grabcad.com/library/degson-dg306-series-5-0-terminal-block-pack-1">here</a> </blockquote> <blockquote> -HDR Aerodynamics Workshop environment:<br> <a href="https://hdrihaven.com/hdri/?c=indoor&h=aerodynamics_workshop">here</a> </blockquote><br>
