Hi,
I have a stock KWA M4 and do not plan to upgrade the internal until it break. Here are some of my question that I have:
1. Can I use a 12v battery on a stock KWA M4?
2. Would it cause more wear and tear using a 12v compared to 11.1v LiPo?
3. What is the comparison in term of ROF using 12v and 11.1v LiPo? I assume the LiPo have a higher ROF

If I plan or have to upgrade the internal to reinforce due to using this high volatge battery (12v), what is the best to upgrade? Thank you beforehand!!!

In the beginning the 12v battery is going to have a higher rof, but it will give a consistent output as the lipo will. I wouldn't use a 12v battery in your kwa! If you wanted to use a 12v battery you wouldn't be able to use a fuse because it would blow, you  would also need to get a ball bearing piston head and a ball bearing spring guide. Just stick with a lipo or a 10.8v battery.

Having ball bearing on BOTH ends is over kill.  Plus they act as a spacer and the spring will get more compressed even in a resting postiing.  Not a good thing.

So, What is my option? I talked to guy at Redwolf, they told me that using 12v is not as bad as 11.1v LiPo battery, off course they can just BS me. How bad would it be to leave my M4 stock and just use those 12v battery, will it last if I control my trigger finger  ;) ? Thanks again guys!!!

IS there a Specific reason why you must use a 12v battery?  FYI, it's outside of our normal operating environment and it will void warranty.

Thank you for the reply beforehand Sir,
I wanted to use 12v because I wanted to get a higher ROF without sacrificing durability too much. I was thinking of 11.1v LiPo but was afraid and dont want to deal with the headache of maintaining LiPo battery (charging, chances of getting the battery/my apartment on fire, and also cost of the battery). I was going to use a 10.8v battery but my dumb a** tell me to use a higher voltage in case if I wanted to upgrade my spring and some internals later on down the road.

As far as warranty, I am not afraid of voiding it. Worse come to worse I will just buy another gearbox from KWA, its decent price plus the more money we all spend for KWA the more cool GUNZ you guys can built...coming from LE/SWAT side, I am really glad that you guys finally made something that can withstand abuse and also great FPS out of the box for realistic scenario trainings, WAY TO GO KWA!!!

Let me ask you this....  How fast do you want your gun to shoot?!  Pushing higher voltage isn't always the answer.  And I'll need a number.   20, 25, 30 ...40 bb's per sec?!!

then I'll tell you if it's feasible or not.

Thank you for the reply once again,
I will be happy with 25-58 RPM :D   If using a 12v not recommended, is it btter to use a LiPo instead. Thank you again!

25-58RPM? are you sure you mean RMP or BPS? and I think that 58 is a tad bit unrealistic.

I guess you want that white BB laser.

The highest record is 40ish BPS done by the Red Alert folks in Taiwan with modification.  And honestly, it really is not necessary to shoot that fast.  If you are in LE you we should already learned trigger control and conserving ammo during training.  And you should know real AR don't even shoot that fast.  

a stock M4 A1 using 11.1v lipo is already doing 23-24 bps.  So I think you should just stick with the original setup.

Sir,
Sorry that was a typo, I didnt even relaized I put 58, I wanted to say 25-28 RPM/BPM. I am not planning to use it all the time (spray and pray) but surely it's nice to have the capability. So, I assume the answer is, its better to use a 11.1v LiPo than using a regular 12v battery? Thanks and this will be my last question  :P and sorry for the trouble

I too am curious about this.

I really want to take advantage of KWA's gearbox in my M4 CQB being built for high ROF right out of the box but I do not want to use LiPo batteries for safety concerns. So I'm wondering if it will be safe for the gearbox to use a 12v NiMh battery (good cells, IB 2000mAh AAs) and how that would effect long term wear and tear compared to a 11.1v LiPo.

Or would I be better off just using a 10.8v NiMh pack to achieve a very high ROF without the safety concerns that come with LiPo or the durability concerns that I have about a 12v NiMh pack?

I have a 11.1 12 c lipo its a hyperion 1100 mah and i have a 10.8 elite 1500 mah.......my 10.8 pushes my motor  harder and has more ROF then my lipo.....both batterys are high end  quality but i think my 10.8 put of over 18amps of discharge.....i like my Nimh battery better it....i think it more rate of fire than a Firefox 1600mah 11.1 too (my friend let me try it out).

It all depends on the discharg rate  (  "c " ). Over 18c is bad for the KM-4s.
