Gave up making a connector due to my shite soldering, the Eagle 6 one has been spot on. Don't need another wire to monitor battery voltage, maybe it's for trigger positive Link to comment Share on other sites More sharing options...
rj1986 Posted December 7, 2023 Share Posted December 7, 2023 I might just be special, but I've manged to squeeze a nunchuck 7.2 lipo (with mini tamiya) into a WiiTech repro handguard. It's tricky but doable - but yes, i admit it would be better with a direct to MR30. I run the cables above the barrel, and the battery at 4 and 8 o'clock. Long Mlok at 6 o'clock with a vert grip and small light. PigDoggy 1 Link to comment Share on other sites More sharing options...

Popular Post PigDoggy Posted December 8, 2023 Popular Post Share Posted December 8, 2023 Magpul stock and handguard along with the M-SL type lower from Japan. Front and rear flip up sights are Magpul MBUS Pro’s. Magpul M-Lok Cantilever mount for the Scout light. Have a rear QD sling pin from HKparts. PTS muzzle and Laylax HK Mode-2 silencer towards the pointy end. chopped down ZCI 100 spring installed. ~325 FPS with .20g bbs/ ~275 FPS with .25g bbs. All else are standard parts. Per the description from impulse101, no mods were required to install the lower. However, on my unit….I opted to sand down less than 0.5mm off of the left side selector lever to create better clearance. The selector would have probably functioned fine without shaving some material down. I ordered another one for one of my SD6’s. I’ll see how that install goes. rj1986, Jacob Wright, lokkers and 3 others 5 1 Link to comment Share on other sites More sharing options...
PigDoggy Posted December 15, 2023 Share Posted December 15, 2023 Moved on from having the mr30 to deans adapter…decided to re-wire my batteries with mr30’s so it plugged straight into the mp5. Deans plugs was definitely easier but I wouldn’t say it was difficult to solder the mr30’s into place. Ended up having to make a deans to mr30 adapter for the charger as well.

Sewdhull Posted December 15, 2023 Share Posted December 15, 2023 I am puzzled, why didn't you put a deans on the rif instead of making 5 new connections? It's up to you ofcourse, but the mr30 is inferior to the dean's in everyway. EDcase 1 Link to comment Share on other sites More sharing options...
EDcase Posted December 15, 2023 Share Posted December 15, 2023 (edited) Yeah, just chop off the mr30's and replace with Deans. (One wire at a time of course 😉) More connectors = wasted power and less space. Edited December 15, 2023 by EDcase Link to comment Share on other sites More sharing options...
PigDoggy Posted December 15, 2023 Share Posted December 15, 2023 There’s 3 cables coming from the gearbox that’s soldered into the mr30 connector. I don’t want to touch that for a few reasons. One, is that there won’t be any place for the third wire as the deans plugs only has 2 leads. Another is that the wires are on the shorter side….I don’t want to go through the process of tearing into the gun to re-wire everything (not to mention the other NGRS mp5’s I own). Third, mr30 should be adequate for the job. The Marui 7.4v 1500mah 35c lipo utilizes the mr30 connector. I’m only running a 7.4v 1300mah 20c lipo. I was running the mr30 to deans adapter for my mp5a5, mp5a4, and mp5 sd6. I just pulled them out of the guns so I can now run the batteries that I soldered mr30’s on. Even if I was running the mr30 to deans adapter and still using the deans plugged battery, the battery is still essentially connected via the mr30 connector. The other 7.4v 1300mah batteries that I was using with the deans connectors on them probably won’t be used for the mp5 anymore unless I end up pulling an mr30 to deans adapter from my box. They’ll be used for the 74mn, M4’s, Scar’s, and MK46 when I switch over to them. 14 minutes ago, EDcase said: Yeah, just chop off the mr30's and replace with Deans.

EDcase Posted December 15, 2023 Share Posted December 15, 2023 Yep, totally up to you. (I thought the gun was wired to Deans) Doesn't make much sense that there are 3 wires going into the mr30 which then connects to only 2 wires on the battery. Two wires must be going to one. (Likely a sensor wire for a MOSFET) Link to comment Share on other sites More sharing options...

(Likely a sensor wire for a MOSFET) Yeah. I’m not sure. The mr30 has three leads on it. Maybe a low voltage cut off built into the Marui trigger system. The Marui 7.4v 1500mah 35c lipo using the mr30 also has 3 wires coming out of it which I assume is for balance charging. on a 7.4v lipo, the connector for balance charging is also the same connector you plug a low voltage monitor/alarm into (when you’re running lipos on RC’s) so you don’t run the batteries too low.

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.

Sewdhull Posted December 15, 2023 Share Posted December 15, 2023 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 Link to comment Share on other sites More sharing options...
Sewdhull Posted December 15, 2023 Share Posted December 15, 2023 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. Link to comment Share on other sites More sharing options...

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.

Sewdhull Posted December 16, 2023 Share Posted December 16, 2023 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. Link to comment Share on other sites More sharing options...
PigDoggy Posted December 16, 2023 Share Posted December 16, 2023 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. Link to comment Share on other sites More sharing options...
Sewdhull Posted December 16, 2023 Share Posted December 16, 2023 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. Link to comment Share on other sites More sharing options...

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 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. Link to comment Share on other sites More sharing options...
1st commando Posted January 3 Share Posted January 3 A G3 or HK33/53 might be interesting although the mp5 is my token AEG now. It's rare I used anything not gas Link to comment Share on other sites More sharing options...
