Need help figuring out MHSV1 parts internal electronics fitment

Hi everybody,

Looking to build my first saber and was wondering if I should go for a 4" Double female threaded connector DF4 or 5" Double female threaded connector DF5 extension.

This section is going to house the NB V2 and a Li-Ion 18650 3.7V 2600mAh PCB Protected Rechargeable Battery Module plus a 2W 28mm Bass Speaker with MHS speaker mount V4

I want to make it as short as possible. What got me worry is that i saw the part, "MHS speaker mount V6 - For 28mm Speakers" said that it need at least 5." I'm not planning on using that part so i was wondering if it will fit. It can't pass the 4" part since I planning on other stuff on the top section.

If i only know the measurement of the Li-Ion 18650 3.7 battery pack.

Thanks for your time.

The 3400 mAh 18650 battery is 2.75" long. I don't know if the 2600 mAh 18650 is the same length. Are you planning on using chassis disk 5?

All 18650 batteries are within a mm or 2 in length of each other length wise. The first 2 numbers (1 is the diameter in mm's and the next 2 (65) are the length in mm's (65 mm). That's how the system works.

There is also a small protection circuit in the battery pack that adds a little bit to the length. I measured my 18650 at 2.75" (about 70mm).

That's why I didn't correct your overall length in inches. You always have to add a little extra.

Good to know.

wow thanks for the quick replay and the useful information!

I was thinking of using the Acrylic Chassis Disc for NB and 18500/18650 pack - S3 (Clear) plus a speaker mount i have yet decide which version.

From what i read so it should fit the 4in extension then. Might be a tight fit with the speaker mount but looks manageable. Thanks everybody for the input!

Draw it out. Some paper, a pencil, and a ruler go a long way in mitigating headaches

Back when I was building sabers on the regular, I made myself a bunch of "mockups" made from plastic card stock that I could use to layout the parts inside a saber to see what would/could fit where and where I might need to adjust either the parts I used or the design. Saved me a lot of headaches when figuring out how to design a saber properly and still get all the goodies inside it that I wanted.

thanks Jonitus for the hint. Not a bad idea!
