Dual Channel Outputs + LiHV Compatibility 

The ProTek R/C "Prodigy 66 Duo AC/DC" LiHV/LiPo/LiFe/NiMH AC/DC Battery Charger is a dual port AC/DC charger that can handle 6S packs, is capable of up to a 6 amp charge rate, worldwide 100V/220V voltage versatility, with two 50 Watts of power... the next generation of Prodigy has arrived.

Two Independent Outputs
The Prodigy 66 DUO AC/DC features dual inputs to simultaneously charge two independent battery packs. This provides the flexibility to set charging parameters independently for each channel to accommodate for nearly any need.  

Hi-Voltage Capable
This charger features a Hi-Voltage LiHV mode that allows you to safely charge Hi-Voltage LiHV capable batteries. You can adjust the charging end voltage of this mode up to 4.40V per cell, which is considerably higher than 4.20V per cell of an ordinary LiPo battery. Charging at this higher end voltage requires a Hi-Voltage LiHV capable battery, but the power gains are significant to the overall punch and power for the R/C model. But please note: battery voltages exceeding 4.20V per cell is prohibited from sanctioned racing rules, such as ROAR, IFMAR, etc.

Dual Power Input
The power source can be 11-18V DC input or a 100-240V AC source. With a builtin power supply, users can directly connect the AC power cord to the main AC input. The power supply can accept AC power from all over the world without the worry of damage.

How To Calculate Your Charging Needs
To determine if this charger is suitable for your application, you must perform this calculation to determine the maximum amp rate the charger can supply. Divide the Watts of the charger by the Voltage of the battery pack. This will tell you the maximum amp rate the charger can deliver (Watts / Voltage = Amps). For example, if using the Touch 625 AC and a 6S LiPo battery, you would divide 200 Watts by 22.2 Volts to realize a 9 Amp charge rate. This means that the charger can supply a maximum of 9 amps to a 22.2 Volt 6S battery. This amp rate will gradually reduce as the battery voltage increases during the charge cycle.

LiPo Battery & Charger Warnings:

1) DO NOT leave the battery in your model when charging
2) DO NOT leave unattended when charging
3) ALWAYS balance charge the battery
4) ALWAYS use a LiPo charging bag
5) YOU MUST use a Li-Poly specific charger to charge the pack (NiMH or NiCd only chargers WILL NOT WORK!)
6) YOU MUST not over discharge the Li-Poly battery pack
7) READ & UNDERSTAND the instructions carefully before operating this battery

WARNING NOTE: This charger is not recommended for use with Traxxas batteries with ID connectors or Spektrum Smart batteries with IC connectors. Charging batteries equipped with ID or IC connectors may require additional steps in order to safely balance charge your Lipo batteries. Please refer to your vehicle or aircraft owner’s manual for recommended batteries and charging equipment.

ProTek RC "Prodigy 66 Duo AC/DC" LiHV/LiPo Battery Balance Charger
Love this charger, Easy to use interface, Best is that i can get one battery up and charging while i set up the second battery on its own interface without jumbling around with trying to cycle on the same interface selecting a different side charging bank like some other charges are made. That is one of the primary reasons i bought this charger over other similar dual chargers that were a few bucks cheaper.

Basically you are getting 2 independent chargers, interfaces, memories, displays, etc. all in one nice convenient unit.
Very glad and satisfied in this purchase.

Also to note you only get 2 Deans Ultra plugs, 1 XT-60 plug (I thought this was an EC3 plug by the pic but i was wrong) and some bullet plugs. So now i need to buy a few Ultra to EC3 adapters.
At least the charger came with 2 balancing boards.

If you are going to charge you batteries inside a "Bat Box" or similar you will need extension cables. Actually extension cables are not a bad idea even when charging in a charge bag. They add a better convenience and room while charging. I have owned a single charging Pro-teck before a battery caught fire and burnt the charger (they were just too close to each other before i caught it with a fire extinguisher, watch those batteries)So buying this 2 charger style was a no brain-er and getting extension wires along with upgrading to a "bat Box" too. No more bags for me, box only!

The descriptions says that it comes with a touch screen stylus pen, BUT I never received that pen. and secondly the screens are NOT touch screen so one is not needed. i think the parts of the description are in error or i am not understanding something.
There 10 memories that you can save different settings. And if you want the same memories on the both sides of the charger you will have to program each side. (I like that so in effect it gives you 20 different possible user saved settings)

ProTek RC "Prodigy 66 Duo AC/DC" LiHV/LiPo Battery Balance Charger
Great charger for the price point. I have only been using it for a few weeks, and so far, so good. It was intuitive to use and did a very good job balancing some older batteries that struggle to fully balance.
