Our Battery Eliminator Circuit is a little device that eliminates the need for a receiver and servo battery pack. It draws higher voltage from the motor batteries and drops it to a voltage level that is suitable for your receiver and servos. This is required in applications which draw high power for multiple servos or use more than 3S motor packs, as most ESCs with linear BECs are not designed for these applications.
Specifications:
Current Output: Peak: 10 amps
Continuous:
<12 volts input = 7 amps*
<24 volts input = 5 amps**Ratings are determined with a 5mph airflow on the BEC. Servo connectors are not rated for current in excess of 5 amps. Users are encouraged to replace the connectors if more than 5 amp currents are anticipated.
Output Voltage: Output 5.1 volts out of the package, user may set output voltage from 4.8 to 9 using the Castle Link (sold separately).
Input Voltage: 5v to 25.2v (2S to 6S LiPo)
Length: 1.2” (30mm)
Width: 0.6” (15mm)
Height: 0.4” (10mm)
Weight: 0.4 oz (11 grams)

if you have an electric radio controlled car you probably have a BEC built into your electric speed controller ESC these usually have 5 to 6v output and about 2-3 amps
when pushing the model to its max sometimes the ESC starves its own internal BEC and your radio might glitch or if its a 2.4 ghz it will loose connection and have to rebind...not a good thing when your going fast as this can take seconds for communications to be reestablished
by mounting this bec directly to your batteries, it will not be starved for power, so the risk of the radio malfuktioning is much less, also this BEC is much more powerful, almost 10 amp at 6v this is a lot of power ! so even if you have very power hungry servos or are powering lights or something else this will do great
with power comes risks and you have to be very careful not to short it out, this unit has no short circuit protection, and will burst into flames if shorted, but this shouldnt be a problem
its fully programmable using the castle link usb device and a computer running the castle link software...this is unfortunately the only way to adjust it...many other BEC have jumpers to configure them...but with the computer you have the option of very finely tune the BEC in increments of 0.1v to get exactly the voltage you need
this thing is a switching power supply, and will emit radio frequency noise, so it should be mounted as far away from your receiver as possible, i mount mine next to my ESC, the wire coming out of it is pretty long and should leave you with plenty of options...use servo or double sided tape to mount
this will not only power your radio controlled models...but you can also use it for many other purposes, i have built a bicycle light system, where i use a 4S 14.8v lipo battery to power two P7 900 lumen LED's and a cree q5 red led...all powered by this little thing, those p7 led's are very powerful and the cree is no slouch either, but this little switching powersupply can feed them all 3, makes for a great bicycle light system with 1800 lumens in front and about 200 rearwards, it will have motorists notice you in traffic, making biking a bit safer in the dark
this thing can not output more volts than its fed so for a 6v application your battery should be more than 6v, if the current drops below the set voltages the output of this BEC will be lower as well
if your using it in wet applications you should shield it from moisture, thick divers silicone grease can keep water out or put a balloon around it
great product, definably recommended
