A TM M14 does indeed have standard connectors for the motor tabs. Many cheap Chinese clone brands solder the motors on as it saves them that much money. To put on motor tabs just snag some Prometheus gold tabs from airsoftparts.ca and stick em on, dead simple. The only problem might be removing all of the solder from the motor tabs. I have had some problems with guns before where there is a tad of solder left and the motor tabs snap because of the extra thickness. But since the motor is total garbage and should be replaced anyway, just toss in a TM EG700 or EG1000 and get some motor pins then your good to go since TM motors don't have solder residue on em.
On that note, I tested the gun before upgrading with several batteries and the results are kinda funny.
7.2V 4200mAh NiMh - 9rps
8.4V 4200mAh NiMh - 9rps
9.6V 3600mAh NiMh - 9rps
10.8V 2000mAh NiMh - 9rps
12V 1300mAh NiCd - 10rps
From 9.6V and up the mini connectors on it where smoking a bit. It was either the mini connectors restricting amperage or the motor really was just maxed out. My later tests with deans and 12awg wire showed that it really was the motor, though the crappy connectors didn't help.
So for CAD$400-500 for a base gun, plus CAD$150-200 in parts from airsoftparts.ca and/or HK, you can have a nice solid EBR. Considering the cheapest main brand EBR is US$600 + a TM M14 or US$1200 complete, this is a really good option for those without the cash. Though remember you get what you pay for.
