I just finished putting some low(er) resistance wiring into my stryfe. I haven't replaced the motors and I've kept the stock switches. I was wondering what the best battery for this blaster would be.

I was considering this:

But I thought a LiPo would be a little bit too much on the stock motors. I've also considered IMRs, but I wouldn't know how many to use. I don't want to use fire batteries because of safety and performance issues. Thoughts?

TRUST FIRES they work great in the stryfe as long as you have taken out the thermistor.

Are you sure? I've heard those are both dangerous and inferior to IMR batteries.

Are... Are you unaware of any of the dangers of unprotected *Fires? If they claim 1000mAh, they're probably lying. I've seen 5000mAh *Fires. Guess what? Bull. Discharge rate? Terrible. Heat, internal resistance? Massive. Plus, they can explode and cause fires.

Deathturtle, you are correct that a Turnigy lipo pack is a good thing. Stock motors may die faster with 2S, but you are going to upgrade those anyway, right?

I wasn't planning to, but I guess I will have to now.
On the subject of motor replacement, where do I buy 180s?

Kyosho Mini-Z Motors are 180. Google search for Mini-Z motor and you will find a ton.

Here you go. This guy usually has them, but make sure they are 12,900 RPM. Sometimes he has different motors with the same picture he uses for "real" 180s. Great price for 3 of them.

that may just be for you but I have put them in all my modified flywheel blasters, so I was just trying to provide info based on my experience.

It's not opinion. Battery ratings aren't user based. Google 'Trustfire explosion,' or similar.

It is a known fact that "fire" batteries can vary from 500mA up to 4A discharge current and most fall in the 2-3A range unless they are cheap low quality cells. The stock motors are made to do with 500mA at best with 4 AA batteries. By giving them a proper power source they can scream to their hearts content. IMR or LI-MN cells discharge 10A-35A burst and should be the only drop in choice anyone considers. Lipo packs like most suggest are expensive but they are far better than any others you can pickup ones that can do 50-100A burst discharge.

Also trust fire and ultra fire are very commonly counterfeited look up counterfeit ultrafire dissection. There are 3 ways they are faked the worst is when they put a 30 mAh foil pack inside an 18650 can and fill the rest with sand or flour or plaster dust so the weight is close enough. There are just cheap cells not made very well these are the fire balls waiting to happen. Then there are 900mA cells labeled 3800mAh.

I would pull cells from laptop batteries before i bought a fire brand. For 14500 cells aw or efest imr are better than any fire and they can do decent amps.

Lithium batteries from a laptop are not high discharge, though. Just FYI.

no they have a discharge of 3-5A but it is a cheaper reliable source of quality cells vs spinning the wheel on a *fire brand battery if you're after 18650 size. 14500 you need to spin the wheel and you should not run any cell other than imr or li-fe. Normal unprotected Li-ion are asking for bad things.

Whoa. I just watched a video of a trustfire explosion and it was insane! Apparently those things can explode even when not in use and are just being stored! I am never buying those things in my life. I am going to have to stick to lipo's forever.

Just be sure to not get the soft package ones and treat them with respect... Sure they are safer but if they get punctured or you exceed the current draw they can violently vent or puff... Nothing good ever spits out of a battery when they vent... I have also read about someone who charged their *fire battery properly they put it in a drawer for use later nothing shorting it or anything he came into his shop after hearing a pop and it was the battery having vented...

Most safe

LiMnimr
NiMHNiMH
LiPolipo

Li-ion quality cellsLi-ion
Cheap Chinese Li-ion *FIRE brandsBoom and Fake
Less safe

In mods with STOCK wiring and motors a good set of IMR or LiMn batteries is fine the stock motors wont draw over 10A.
In mods with Alternate high voltage motors LiPo, LiFe or NiMH packs. You can use these with stock motors but thermal fuses must in most cases be removed.
In mods with alternate low voltage motors A 1s LiPo LiFe or NiMH or AA NiMH are the choice you need to keep in mind most of these motors are 3v they can be over volted a bit to 4.5 or maybe 6v at most...


also any battery that gets abused can explode including alkaline...
