I feel like the chinese building so many batteries recently for customers

0.1 copper and 0.1 plated nickel

JBD 100/300A BMS

10AWG discharge, 16AWG charge

Discharge port AS150 and charge port XT60

I did a bms swap from the old JBD 100/300a to the JK 200/350A BMS, the main reason was bottleneck issues, the Tenpower 50XG were never warmer than 35° on the jbd and on the first run with the jk they reached it, so they dont feel as wasted. But my jbd was in fact also defective showed 100mV difference the entire time while everything was fine on the JK. Also redid a lot of bad soldering and have thicker wires now (from 10awg to 8awg). I also redid balance leads and now my vescs fit better in my scooter and I can probably decrease the spacer size!

Also left a small easter egg ;)

0.15 copper and 0.1 nickel plated.

8AWG and AS150 connector

JBD 100/300A

made for Ninebot G3

0,15mm Laser cut copper sheets with 0,1 mm plated nickel

3D printed Cellholder JBD 100/300A BMS AwithZ uf20b Spotwelder

Copper busbars (I think 1,5x3mm thick) for the most part, at the ends I have 10awg split to both sides where they connect to AS150 connectors.

Build for my dual motor Ninebot G30 (100kmh) love the range and the power. Vdrop is minimal too, around 150mV per group at ~130a. Battery has also never gotten warmer than 30°C even when charging with 20a.
