8.4v v 9.6v batteries

Kashkai

Hi all

My current stock of batteries are all 8.4v. I was wondering if a 9.6v battery might give my M4 some more "oomph", i.e. a bit of extra range and power? Or does the extra voltage in the larger battery just give you more shots?

I don't want to go down the road of putting in a tighter barrel at this stage because the M4 is still new-ish and it already has a 6.03 barrel in it.

Thanks

9.6v Ups the rate of fire, the mAh rating of the battery denotes how long it'll last or the amount of sustained juice it'll supply. The voltage controls the speed of the motor (If the motor's able for it, most are) only real down side to a 9.6v is a little more carbon build up on the trigger contacts (which is negligible) and the amount of bbs you'll be putting through it... Not exactly a bad thing either if you ask me. Batteries don't really effect range or power, that'll be the whole air side of the set up (piston, spring, hopup, air seal, etc.)

Hope this helps.

Thanks for that. As I fire single shot most of the time, no point in getting the bigger battery then.

Could help with the trigger response... Turns the motor faster.

+1 one that

Dave if you're mainly using semi you're best off with a 9.6, I use an 8.4 in my Raider for semi and it keeps up but rob a 9.6V of a mate of mine when I can. higher voltage will ware parts down faster but the difference in ware and tear vs 8.4 and 9.6 is so small you're best going for the 9.6, or a 7.4 lipo if you're up for making the change

Mmmmmm...... I might just pop into hobby in Rathcoole and pick me up a 9.6v to try it out then as I'm off to Redbarn it the morning.

Now what would happen if I went all Rambo on full auto with a 9.6v? Would the gun self destruct in no time? What parts would wear out quickest with a higher voltage battery anyway, the motor, gearbox?

Must get into the technical side of this hobby now that I can now shoot straight and I'm no longer a member of the "bb magnet" fraternity, ie I get far more kills than hits these days:D

An aeg will be fine on a 9.6v battery. It's what I used to run before picking up a pair of 7.4v 2000mah lipos. One will last a whole day no problems and runs my pdw at 20bbs per second.
Wear will be arching at the contacts but these can be cleaned or you can install a MOSFET which will take the load off the trigger so they won't arch really. Mosfets can be active braking or non active breaking if you want to save some money. A basic MOSFET is €5-10 in parts to make with a soldering iron. I'll be making 5 and the cost of each works out at €5-€6.
Other places of wear would be the piston, more so if it has all plastic teeth and angle of engagement hasn't been done.
If the gears aren't shimmed and the motor height a bit too low or high the gears will wear a bit more.

But these areas of wear will be fine. Rule of thumb is, if it can run 8.4 it an run 9.6. It should run for a few thousand rounds anyway, it shouldn't break unless the gearbox was wore already, in which case any battery would have broken it that day.

So to summarise, 9.6 is fine and safe.
Another suggestion I would make though is to switch over to xt60 connectors from basic tamiya. They'll give better response. They'll wear the trigger contacts a tiny bit more but a MOSFET will fix that.
