WARRANTY
A new, unused battery pack is
guaranteed against manufacturer’s
defects and workmanship. Any
damage due to misuse by the
user will be repaired at the user’s
expense. XRAY assumes no liability
for damages that arise from use or
misuse of the battery pack.
XMC 300R ELECTRONIC SPEED CONTROLLER
The XRAY XMC300R is an ESC (electronic speed controller) that has been specially designed for using up to a 370 Super
Size motor in the XRAY M18T/MT micro truck. Based on SMD technology, the result is a very small high-quality electronic
device. This forward-only ESC features proportional throttle/braking and battery elimination circuitry (BEC). An on-board
LED indicates the correct connection of ESC with the power supply, and proper operation (forward and brakes).
RECYCLE THE BATTERY PACK!
DO NOT DISPOSE OF IN FIRE!
XMS01MG MICRO SERVO
The high-quality metal-gear micro servo has been specially chosen for the M18T/MT because of its high precision, long
life and high quality.
370 SUPER SIZE MOTOR
The 370 Super Size motor provides ultra-high performance when used
with the included 6-cell micro battery pack. The motor includes an
integrated capacitor board so you do not need to solder any additional
capacitors.
MICRO BATTERY PACK
The 6-cell micro battery pack is designed to perfectly fit the M18T/MT, and is recommended for use only with the 370
Super Size motor and XMC300R ESC. The high-capacity NiMH 2/3A cells give excellent performance.
BATTERY MAINTENANCE
To achieve maximum performance of the batteries and ensure reliability, please follow these instructions:
CHARGING
We strongly recommend using a high-quality peak-detection charger with automatic shut-off.
The charger should be specifically designed for charging rechargeable nickel metal hydride (NiMH) cells.
For initial charging, set the charge current to 120 mA and charge for 14 hrs for 1200mAh battery pack or set the charge
current to 140 mA and charge for 14 hrs for 1400mAh battery pack.
For rapid charging, set the charge current to 1.2 maps (1200mAh) or to 1.4 maps (1400mAh). If rapid charging is
done at a higher current, the battery pack may generate too much heat and explode or vent.
Never leave the battery pack unattended while it is charging.
If the battery pack becomes too hot (113°F or higher), stop charging immediately.
Slow charge (initial 1200mAh): 120 mAh x 14 hours
Rapid charge: 1.2 maps x 1 hour
Slow charge (initial 1400mAh): 140 mAh x 14 hours
Rapid charge: 1.4 maps x 1 hour
DISCHARGING AND STORAGE
After use, we do not recommend discharging the pack completely, as this will damage the pack. You can safely recharge
the pack immediately after use without any performance degradation. If you will be storing the pack for longer than a
few days, partially discharging the pack down to approximately 40% capacity.
For charging use the included
#389130 charging cable
