The JETImodel MAX BEC is a high-quality linear voltage regulator designed to provide a consistent and reliable voltage supply to receivers and servos in RC models. It is ideal for models powered by 2 LiXX cells or 5-6 NiXX cells, ensuring smooth servo operation throughout the flight.
Product Features
Stable Voltage Output:
- Ensures a constant servo voltage during the entire flight, resulting in smooth servo motion.
- Output voltage options (5.0V, 5.4V, 5.7V, 6.0V) are selected via a jumper plug.
Wide Input Voltage Range:
- Compatible with 2 LiXX cells or 5-6 NiXX cells.
- Recommended input voltage: 5.5 - 8.4V.
- Maximum input voltage: 16V.
LED Voltage Indicators:
- Four LEDs indicate input voltage status.
- Three green LEDs indicate an input voltage above 7.0V.
- LEDs turn off sequentially as voltage drops (below 7V, 6.7V, 6.45V).
- A red LED indicates when input voltage is under 6.5V, signaling that the cells are discharged.
Convenient Charging:
- Equipped with a parallel-connected 3-link JR connector for cell charging without disconnecting power connectors.

Current Carrying Capacity Calculation
The maximum current for linear voltage regulators is determined by the maximum power loss in watts divided by the difference between the input voltage and the set output voltage. Proper cooling is essential, and linear voltage regulators should not be packed in foam or similar materials.
Example Calculation:
- Max. Power Loss: 7W
- Battery Voltage (LiPo): 7.2V
- Set Output Voltage: 5.4V
- Differential Voltage: 1.8V (7.2V - 5.4V)
- Max Current: 7W1.8V≈3.88A\frac{7W}{1.8V} \approx 3.88A1.8V7W≈3.88A
