Portertown: As Onedesign1 said, a Fuse is NOT a absolute necessity. I have NEVER used one in a box mod. BUT, I have used them in Tube type Mech. Mods, just for that LITTLE bit of safety, or "Illusion" of safety. I forgot the name of the fuse, but there is one made called something like Saf T Fuse, or Vape Safe, or something like that. It looks tobe the size of a battery exactly, about 18mm. And, It has a set blow point. It is NON reuseable. It pops, you buy a new one. I've NEVER popped one, And, that is even on my Hades 26650 battery Mod by Footoon. With the Sony Big Amp battery. Using a .3 ohm partially home made atty. Dual coil. STill didn't blow. But, on a short, they WILL BLOW. I've seen it on others. A Sigelei Mod. shorted internally, and the fuse Popped. It pops, u use one of the extras you bought when you bought the original (hint). Does NOT hurt to put a fuse in a box mod, as long as you realize that a poorly made fuse holder, will have SOME voltage drop. (VERY little), so don't buy CHEAP. I have to run several hundred Metre runs of what is called "Hard Line" antenna cable, to go from radio/amplifier to Antenna, WAY up on Tower, way away from house. THAT much cable, DOES insert some NOTICeable impedance/resistance. And, must be taken into account. IOW, everything you put between a source and a load, inserts SOME small amount of resistance, It all adds up.
I've given you reasons to USE a fuse, and NOT to use it, now, as in all things, it's UP to YOU!

Always research and build the safest way. I'm not in a position to understand your complete design. The chip has built in safety measures such as short circuit, reverse polarity, low resistance etc. As is you do not necessarily need fuses....but extra is never a bad thing. I'm sure there's a experienced person or 2 who will chime in.
Oh, come one! NO such thing as TOO much..... I'm using 4 x 26650's. Parallel of course. Let's see now, at .2 ohms, how many days/hours is that????????????????
Just one last picture wich one would look better the white teak burl or this redwood lace burl.
Just let me know since I am undecided.

VewDew, what are u doing in this forum? You don't have SX350...... You have DNA30d, NOT installed yet....... BRAND NEW one. I KNOW, I was your local friendly DNA sales Person , on Ebay.
Beautiful Mods. Wish I could do something like that. BUT, My age, and previous injuries many years ago, have shut down my ability to do small soldering. I Must now defer to the younger generation for assistance. Hard to admit. But, I've one SX350 back at Onedesign1's place, I MIGHT have bridged two traces on a board, and now, NO more lites. No smoke though. So I've officially stopped all small soldering. IF not ALL soldering.
Good luck on your mods, I don't think you'll need the luck though. Beautiful work. I STILL build some VERY high power RF amplifiers, for friends in SOuth America, as their Laws permit it, Our laws here, do NOT. 2KW Max. Input Power.
