Thinking about building a 70A duel 18650 unregulated unprotected box mod for competitions

[Ryan419]

So from the reading I've done when you have duel 18650 in parallel you not only double the mAh but the Amps as well.

So found a switch (only $3.50) that can take 60A at 120V DC and 40A at 240v DC at 240V just waiting to find out if it can do 70+A at 4.2A and less.
Its not very pretty sticks out kinda far and is rubber but if it can handle a 70A pulse I will not need a mosfet and 15 k ohm resistor.
Might try to find 35A fuses like the 15A that come in the dyi kit.
Not having much luck finding one though anyone know if a 35A car fuse would work?
But if not staying at .06 ohm + should still be safe for one hit at a competition!

So want to know what other cloud chasers think of this?

yes you can use the car fuses

I've not found a momentary switch that is actually rated for anything near 60ADC. I bought one on ebay that was advertised as such but I don't trust it.

Is this the one you're talking about? I don't trust chinese ebay pages at all. Grainger I trust though. Lower Voltage DOES NOT mean more amperage.

Quigsworth says the car fuses are fine for mods and I trust him wholeheartedly. He knows his stuff.

Be looking at wicking methods though. I haven't found anything that'll keep up even at 190W (which I have done on a series mech box). You're talking about 294W.

PS - I think it's dual. Duels end in one of the parties dying.
