What is the maximum voltage for the XL5 ESC? ›

To activate Low-Voltage Detection (LiPo setting):

Make sure the LED on the XL-5 is on and shines red. 2. Press and hold the EZ-SET® button (the LED will turn off) (A). After ten seconds, the motor will beep twice and the LED will shine green.

1. ESC and motor: The motor ERPM must be smaller than ESC ERPM. 2. Battery and motor: The battery voltage must be less than or equal to the motor voltage.

4-7 NiMH cells or 2 LiPo cells (2S) Only: The XL-5 can only accept a maximum input voltage of 8.4 volts.

The default cutoff per cell is 3.2v, but always check with your LiPo manufacturer to verify their recommended minimum discharge voltage. Click UPDATE and send new settings to your ESC.

The XL-5 is limited to motors with no fewer than 15-turns (540 size).

Solid Green: Power-on light. Low-Voltage Detection is ACTIVATED (LiPo setting). Solid Red: Power-on light. Low-Voltage Detection is DISABLED (NiCad/NiMH setting).

There are 3 phases in an ESC, each motor pad corresponds to a phase. If one of those phases is damaged, your motor will stutter (won't spin up full speed but rather it just twitches). Usually it has to do with bad MOSFET – the 8-pin surface mount chips on the board.

Meanwhile, a flashing ESC light means that the system is activated and working as it should, which is something you shouldn't worry about. In most cases, the ESC system will engage when it detects that the roads are slippery or icy.

ESC Voltage

ESCs have a maximum voltage limit that may be given as a voltage range or a cell range. For example, an ESC rated for 3S - 8S cells will support a voltage of 11.1 - 33.6 V.

What is the battery limit on the Traxxas xl5? ›

4 to 8-Cells Only: The XL-5 can only accept a maximum input voltage of 9.6 volts. Always adhere to the minimum and maximum limitations of the XL-5 as stated in the specifications table. Use Stock Connectors: If you decide to change the battery or motor connectors, only change one battery or motor connector at a time.

The ESC current rating (or “amp rating”) indicates the maximum current an ESC can handle without damage. Keep in mind that this is NOT the amount of current pushed to the motors, it's just a limit, so don't worry about it being “too large”. An amp rating can never be too high, only too low.

Whatever voltage your receiver battery or speed control puts into the receiver is what the receiver will deliver to the servos. The Traxxas 2.4GHz receiver is designed for use with 6-volt receiver packs (4 alkaline cells or 5 NiMh cells) and any electronic speed control.
