TM MP5 NGRS Owners

Did it come wired to mr30 from new?   Might be a new thing

Yes. The Mr30 plugs were factory Marui install. The NGRS MK46 Mod 0 has it as does the Marui P90 Plus.

Mr30 is a new thing by Marui.

said guns came wired for mr30 and had an mr30 to mini tamiya adaptor from the factory.

 
So it seems the TM battery has no seperate balance connector, but it does have a Battery management system covering balance charging, over and under charging and discharging and battery temperature.

What the extra wire is I dunno, or why the rif needs one I also don't know.

Maybe there's a manual somewhere

 
If it were me, putting a lipo of that type in a recoiling gun, I'd pad the battery bay enough to stop the battery rattling around. I notice TM put thiers in a hard case.

 Here ya go bro....  

That battery plugs directly into the ECU/Receiver of the Traxxas TRX4M. The battery has 3 wires coming off of it (no other connectors)...where it plugs in also has 3 prongs to accommodate the connector with the three wires coming out of the battery.

The charger for the battery also has three prongs/wires for it. The connector from the battery is also the balancer/charging connector for the OE marui battery.

I believe the trigger unit on these new marui's have a low voltage detector and will cut off operation when the marui lipo battery is running low.

Most etus have some low battery detection, no need for a third wire.

Say the 3rd wire has no voltage on it because you use a 2 wire battery on it, if the etu was measuring voltage it would measure 0v and the rif would not work right?

Bottom line is that TM have added a BMS to the battery for whatever reason along with a connector no one else uses.

Drone types do use this connector, but that's because brushless motors have 3 voltage supplies from the speed controller altho I preferred to save weight and use bullet connectors.

Honestly tho, balance charging on a 2 cell battery is probably unnecessary, but still better than not doing it.

 
It hasn’t been an important thing for me to look into why TM really decided to use three wire setups to run their electronics…. I’m sure they have a good reason….their newer aeg’s now utilize them to be used in conjunction with the Marui lipo battery.

You can still use regular nicad/nimh/ and other lipo batteries that use two wires for the power output.

I opted to wire my lipos for mr30 so it looks neater (and to save compartment space) than having that mr30 to deans adapter. I’ve ran my mp5’s like that the past couple of years with no I’ll effect. I just felt the need to get mr30 connectors.

If I pick up another mp5 (probably another MP5A4), I won’t need to change connectors on other batteries. I have another MP5 SD6 in the closet that I’m thinking about turning into an SD5….and that A4 that I’m looking at maybe getting gets turned into another MP5A5. Maybe just do a basic surefire 628 handguard install and call it a day.

 
You're right, it isn't important, I don't even have one. I'm guessing things like this are to make things proprietary. Clearly the third wire has no discernible function on the rif.

 
Which ones your favourite? Looks wise it’s the SD for me but I really prefer the full stock when using one.

Honestly, they are all equally fun. It’s fun to install the exterior accessories on them. I ran them with tracer units on so they were essentially the same length….virtually the same.

my go to has been the sd6 primarily because of the fact that I can run my camera over the suppressor.

at some point I’ll get camera mounts for the suppressors I have for the other two as well.

 
It pains me to admit this but having just got my MP5 it seems TM have actually got it right with these

They did and I've said before that I think this is the best AEG TM have made so far. It will be interesting to see where TM go with the design. I'd imagine a MP5K is on the cards with a stupid battery option in the front grip and hopefully after that a G3 recoil. TM have a history with making G3's so I can see them going down the G3 route again hopefully.

 
A G3 or HK33/53 might be interesting although the mp5 is my token AEG now. It's rare I used anything not gas

 
Someone tell me why I shouldn't treat myself to the A4?

Also, are there any clones of the magpul grip about?

Do it.

And you mean like the one at the top of the last page? Yes.

Sorry, I meant front grip. All I can find the the kosher magpul one which seems a bit steep compared to the price of the gun 

 
I don’t think there is yet, surprisingly.

They do pop up for sale on here every now and then.

I’ve been trying to resist buying another one myself so I can convert my other SD6 into an SD5.  then have a plain looking A5. 
 

my  a5 turned into this….the other one ended up with one of my friends ?

Got the vfc mp5 flashlight handguard mounted on the A4.

had to do a tiny bit of dremel work for the back tab that goes into the upper receiver. The part of the outer barrel under the cocking tube (where there’s a Phillips screw) comes into contact with the top of the tab so I sanded it down some. 
 

the holes for the retaining pin is oblong. The stock pin will still stay in place but I opted to use the handguard pin that came with my Magpul SL mp5 handguard as the flashlight handguard won’t need to come off anyway. Figured this way, the pin (which has a screw threading into it) locks the handguard into place.
