Description:

If you want a switch that offers complete dual battery balancing and redundancy with an ultra-small footprint for your scale model then look no further. The new Booma RC intelligent redundant battery balancing switch is the answer.

This switch works with any single or dual battery system. Works with battery chemistry and voltage range from 2.5v to 28v. It comes with a Pin Flag and Ultra Bright Blue LED which can be mounted discretely on your scale model. The Pin Flag controls the internally mounted switch and battery redundancy circuit. The result - beautiful scale appearance with dual battery redundancy peace of mind.

This new balancing technology offers zero voltage drop battery balancing and redundancy which means it can handle huge loads without generating heat. This also means your receiver and servos get all the power unlike conventional battery balancing which loses precious power as heat.

Package Includes:

• 1 x Pin Flag Switch with mounting hardware.

• 1 x Ultra Bright Blue LED with mounting hardware.

• 1 x Dual Battery Balancing power switch circuit.

• 2 x sets of Input and Output JR connectors.

Specs:

• Ultra low foot print for the best scale looks.

• Works with single or dual battery configuration.

• Works with all battery chemistries. LiFe. LiPo, Lion, NiMh, NiCD. Battery voltage range can be from 2.5volts to 28 volts.

• Capable of handling input voltages up to 28volts.

•  Minimal external footprint - All you see on the outside of your model is a 3mm Pin Flag socket and (if required) an ultra-high bright Blue LED. The Pin Flag controls the internal power switch and dual battery redundancy.

• Full Dual Battery Redundancy - If one battery fails the other battery takes full control.

•  Maximum Battery Power Balancing - In a dual battery system HS1 draws current proportionally from both batteries while moving both batteries to a complete load balance situation. This means you get the maximum capacity out of both batteries all the time.

• 2 x 25 amp independent circuits. HS1 is 2 x 25amp circuits into a high power matching battery redundancy circuit. HS1 actually uses 4 x 50 amp rated FET circuits for battery power matching. We passively rate HS1 at 25amps per circuit.

Power HD B3S Brushless Servo - 40kg/cm (555.5 oz/in), 0.08sec 8.4V - (High Speed and SR/SXR/SSR/SUR/SFR Compatible)

Check out the new Power HD 0804HV Brushless servos!

These are great to use a throttle servo and can be used in systems with other high voltage servos!

The Power HD 0804HV high voltage servos are made with brushless technology. Now - we've heard about this "brushless" stuff before but it is time to ask the question on all of our minds - why is that so great? Take a brushless motor for example - no brushes in a brushless motor (no kidding...) nor does it have the commutator - instead a small circuit board coordinates the energy delivery to the windings. Think about this technology being used in a power tool - since the electronics communicate directly with the stationary windings the tool can adapt to its surroundings - only using enough juice necessary to accomplish the job. So if you are using a brushless drill to drive a screw into Styrofoam - it will sense the lack of resistance from the foam and pulls only enough charge from the battery that it needs. Whereas a brushed drill will run as fast and hard as it can no matter the job simultaneously wasting your battery life.

"What the heck does that have to do with my servo?" Well now they are incorporating that smart technology into these HD 0804HV high voltage servos - so they are not going to be sucking the life of your Redwing LiFe battery when it doesn't have to - which means not only would you be getting a great and powerful servo - it's smart! Your "LiFe" will thank you.

These servos are high efficiency and perform better. They run cooler and quieter and with less vibration - because there are no brush arcings, the radio frequency interference and electronic noise is significantly reduced.

All aluminum housing, high voltage and the new brushless technology gives you the best strength and speed while being incredibly efficient and long lasting.

So now the only question is - why are you still reading this? Go buy your Power HD 0804HV servos before they're gone!
