Maxa beam : RE : MaXa project #2

[HID mania]

Today, I reinforced the lines carrying high current.

As I mentioned last time, honestly, I have no complaints about the performance of the Maxa Beam.

However, I have now figured out a way to overclock the Maxa Beam to operate at over 100W of power, and I reinforced it because I felt that some of the PCB patterns were too thin in comparison and were not effective for current transfer.

3030 size cooling fan. It is scheduled to be installed on the rear.

The reason the reinforcement wiring was routed toward the bottom of the PCB was to reduce interference from the top of the PCB regarding airflow for cooling.

As previously mentioned, all solder used is Mundorf Silver Gold Supreme Solder.

It is a premium solder containing a large amount of silver and copper, offering excellent electrical conductivity. It is suitable for maxa beams.

Other details not mentioned: I have switched the screws to metric screws. because inch standards are not used in South Korea.

Additionally, most existing steel screws have been replaced with aluminum screws, and care has been taken to further reduce weight by using screws that are a few millimeters shorter in parts that do not significantly affect durability.

Update : finally i got "2026 style ultra-high capacity 21700 cell" (total 21cell i have)

Each cell provide 6500mah, maybe If calculate the final battery wattage, it is expected to be approximately 473W. (Since efficiency drops to about 90% after passing through both the BMS and the DCDC converter... about 10% is wasted.)

currently designing an aluminum battery case.

Nice.
