I was going to get the Neo Rhino motors until the Fang Revamped motors came out. Since I've spent $200 modding my stryfe, I really don't want to buy a lipo & charger when I have IMR's already. My question is, can I run the Fang Revamped motors on 3 IMR's & a dummy?? 4 IMR's?? I know it's not recommended but I don't plan on entering any games soon. Maybe 1 day I will go with my son. Also, what's the pros & cons of 3 or 4 IMR's vs the 2s lipo?

Thanks!

This is a question you should ask the seller of said motor.

The issue with most IMR's is that they only supply around 5-10 amps per battery. They really shouldn't be used with any aftermarket motors. The revamps are 28 amps at stall per motor (so 56 amps per set). Three IMR's will not gives it enough amps in a stall situation. This will cause your batteries to be at greater risk of fire or frying your switch. IMR's are usually poorly manufactured and aren't really made for this application. If you are stuck with a 14500 form factor look at LIFE4POS batteries. They are much safer chemistry but still aren't optimal for your setup. $200 for a stryfe is pretty crazy. I usually build mine for around $60-$70. Also the revamps would spin at around 55,000 rpms on three IMR's which is why too fast for every brushed motor cage except the eclipse (Skip the eclipse until the 2nd gen wheels come out)

 

TLDR: Skip IMR's due to fire risk and go to LIFE4POS if stuck on 14500 size. They are safer chemistry. Use 7.4 volts.

How did you spend $200 on a Stryfe and NOT have any LiPo gear?

 

You might be able to get away with a NIMH or NICD pack, but NOT IMR's. Bert81 gave a very generous discharge estimation. You should probably assume that IMR's discharge 3-6 amps.

 

Also, using 3 IMR's would be overvolting the motors, which would cause them to run at 50K RPM, which unless you have a high crush cage, isn't optimal for performance.

 

If the entry cost of LiPo tech is discouraging you, the Turnigy E3 costs around $10 and can balance charge 2s and 3s batteries.

Really, any battery setup will cost around the same as a correct setup. Getting the cells that won't work in NERF and their charger should cost about the same as a lipo (or other pack) and a charger. The cells just aren't ideal for the application. If OP is avoiding Lipo because of cost, they're functionally admitting they're avoiding any battery setup because they'll all cost $30-60 to set up.

 

I didn't want a charger and pack to monitor just for Nerf, so I went with another pack I had and used already for something else: My power tool packs. If OP does do something else that uses worthwhile batteries (droning, RC, airsoft, handiwork), overlapping the battery use brings the cost down for both uses.

What I was really trying to say was that I'm not using this thing for anything but shooting my son & family members & that I already spent $40 bucks on a battery setup. I already over spent on it with a full worker kit, all the little mods, mags & hundreds of darts, & now I'm doing the internals. I guess you could call me a hobbyist but I refer to myself as someone who can't stand stock stuff! My jeep build has $12k in parts alone turning it into a rock crawler. I used to do rc stuff & built my own instead of off the shelf. Even my real firearms have all the bells & whistles.

Basically I just wanted to know if I can run it like that for a little while until I decide to buy another battery set up.

P.S. I think I just realized that the setup I want wont work unless I do run a lipo. If I can't get the torque needed for a high crush setup then it won't work period. Thanx for all the advice!!

You can use many types of hobby or tool pack, but yeah; individual cells can't power a high crush setup.

I am the maker of the motors.  Please do not use any 14500 batteries with aftermarket motors.  It is dangerous even with "safe" chemistries as the cell can vent hot gasses when you overload the battery.  This will melt a big ole hole in your fancy new blaster and possibly your hand.  I have heard of 2 instances of IMR cells venting in our hobby and melting a hole in the blaster.

Neo Rhinos have more torque due to running on 3s voltage instead of 2s.  All this really means is they rev .16 seconds faster than the fang revamps with Cyclone wheels (on the heavy side, lighter wheels will have less of a difference).

So if you ran Rhinos on a 2s, then ran Fang Revamped motors on a 2s, who would win?

Fang motors, because they are balanced for a 2s setup, also, running a 3s setup requires you to get an expanded battery tray

Im sure there are some setups that are *way way more*, but using IMRs+ Charger appears to cost about what a Lipo/other pack + *basic* charger would.

My 20v Lion setup would have cost ~$50 if I bought it by itself, which is probably more than IMRs. But I instead paid ~$80 and got a drill AND the battery, charger, and sacrificial adapter.

So my question to that is then what happens if you run the Fang Rev on a 3s? I know it's a 2s motor but they do say you can run it on a 3s. (& yes i know that voids the warrantee).

I was going the other direction.  I power and charge a 2S Demo with stuff I've salvaged for about $5.03, which includes the three copper pennies I'm using for contacts.

Just an fyi, i went with a 42.5mm Morpheus cage w/guide, Revamped motors, worker wheels, 21a microswitch, & a 2s lipo.

I'm replacing the worker wheels with smooth wheels from out of darts insutanto wheels cause I felt that the groves on them were ripping dart heads off. I think a smooth wheel won't rip heads off cause there's no groves to pull the heads off.
