I bought an Emaxx 3906 on Craigslist. it's a stock 14.4 with Novak 14.4 ESC without low voltage detection. The guy I bought it from decided to use 2 Turnigy LIPO 3800mah 2S1P 7.4 25C Batteries. Will the Lipos kill my ESC or will they kill the Titans ? do I really need a "Low Voltage Detector" ? you can "Floor" the throttle from a dead stop, the ESC won't give the motors all of the juice at once. you have to ease into the throttle and then "Floor it", the motors light up quite nicely.

Lipos can be damaged if the voltage goes below 3.0 volts per cell. Since the esc doesn't have LVC you need another way to protect the looks and that's with a low voltage alarm. In extreme cases of running lipos too low they can puff and possibly catch fire.

I doubt its it's the esc that's preventing full power from going to the motors. Instead check the slipper clutch. Sounds like the slipper clutch is slipping under full power from a stop and lower speeds hurting acceleration. There's a nut on the input shaft of the transmission in the center of the spur gear. Tighten the but until it stops (dont crank it down) then back it off 1/4 turn. Your slipper should now be properly adjusted and right enough to transmit full power to wheels while protecting the drivetrain.

it's not the slipper clutch. you have to ease into the throttle, it won't take full throttle from a dead stop, when I "floor it" from a dead stop nothing happens, no energy is transferred, it truck is dead quiet. you ease into the throttle, get the truck rolling, and then you can floor it. it wants to pull wheelies. I did run it until it slowed from lack of battery power, all was fine, I charged the Lipos and it runs great. I have seen the Low Voltage alarms, but I have to buy 1 for each battery.

That's how the esc is programmed. It's dialed back a bit so you don't start snapping drive lines.

you can get a new evx-2 lvd from traxxas for $50.00 and your old esc
