This is the Thunder Power TP820CD 20A Dual Port Battery Charger. The dual port TP820CD is the most anticipated, most powerful and most advanced multi-chemistry battery charger system available from Thunder Power RC. With up to 800 watts of total charging power, the TP820CD is equipped with two ports that function completely independently to charge, discharge and cycle a wide variety of 1-8S LiPo, LiIon and LiFe (A123) batteries, as well as 1-24 cell NiCd / NiMH cells and 6-30V Pb (lead-acid) batteries! The built-in 2-8S LiPo/LiIon/LiFe (A123) cell balancers, one for each port, and included balance connector adapter boards are readily compatible with all Thunder Power balance connectors and the JST-XH balance connectors found on many other batteries.

The dual port TP820CD offers the convenience and flexibility of two separate chargers in a single yet incredibly compact case as a result of its advanced power conversion technology and an exclusive Thunder Power RC design. Each port is capable of charging at rates up to 20 amps, even simultaneously depending on input power and charge settings, offering the ability to charge many of the latest-generation LiPo batteries at ultra-fast rates up to 6C and beyond. This means the TP820CD is well-equipped to quickly charge batteries up to 8S on each port, as well as Ďsplití batteries equipped with interconnect leads up to 16S by using both ports simultaneously.

Popular examples of the incredible charging capabilities of the TP820CD are the ability to charge two 5S 5000mAh batteries, one on each port simultaneously at rates up to 4C, or two 6S 5000mAh batteries at rates more than 3C, to have a complete 10S or 12S 5000mAh battery setup charged in as little as 15 minutes or less time! Thatís even faster than single port chargers rated at higher current and wattage output, without the need for cumbersome parallel charging and an even more powerful power supply, and without giving up the added convenience and flexibility that independent dual port charge, discharge and cycling functionality offers. Because each port functions independently you can even mix and match charge, discharge or cycling duties of a LiPo motor power battery and a NiMH transmitter battery, a NiCd receiver battery and a lead-acid field box battery or just about any other combination you might have.

Additional features include built-in data logging and viewing on the large class-leading and easy-to-read 48-character blue backlit LCD screen, internal resistance measurement and an advanced Storage Mode function to automatically charge or discharge LiPo/LiIon/LiFe (A123) batteries as needed. Other great features also include dual computer-controlled cooling fans and temperature protection, an attractive and extremely durable aluminum case, plus the ability to install future firmware updates available for free using a standard mini USB cable. Best of all these incredible features are all available at a value thatís hard to beat while being fully supported and backed by Thunder Power RCís 2-year warranty.

Features:

  • Powerful all-in-one dual port charger, discharger and cycler system with built-in LiPo/LiIon/LiFe (A123) cell balancers that offer maximum safety, performance and easy-to-see individual cell voltages.
  • The included balance connector adapter boards (2pcs) allow the built-in balancers to be used with 2-8S Thunder Power-compatible balance connectors as well as the JST-XH balance connectors found on many other brand batteries from ProTek R/C, Align, Dynamite, E-flite, ParkZone and more.
  • Convenient and flexible dual (two) port design charges, discharges and cycles 1-8S LiPo/LiIon/LiFe (A123), 1-24 cell NiCd/NiMH and 6-30V Pb (lead-acid) batteries on each port independently or simultaneously.
  • More than double the charging power, up to 800 watts total (400 watts per port), of other similar class chargers with selectable charge rates from 0.2 amps up to 20 amps for each port.
  • The perfect choice for safe and ultra-fast charging at rates of 3-6C and beyond for the latest-generation LiPo batteries.
  • Charge two 5S or 6S 5000mAh batteries at rates up to 4C for 10S or 12S battery setup charge times of as little as 15 minutes or less* Ė even faster than single port chargers that require cumbersome parallel charging and a more powerful power supply.
  • Advanced Storage Mode function for LiPo/LiIon/LiFe (A123) batteries will automatically charge or discharge as needed to achieve storage level voltage.
  • 24 user-programmable memories plus built-in data logging and viewing with internal resistance measurement, battery voltage, input voltage, temperature and more.
  • Fully-adjustable charge capacity limit, per cell end voltage and low voltage cutoff settings for all chemistries to maximize safety, charge and discharge performance.
  • Durable and compact aluminum case with dual computer-controlled cooling fans and a large, class-leading and easy-to-read 48-character blue backlit LCD screen.
  • Wide input voltage range from 10.5-28.0V for higher efficiency and power output when using 24.0-28.0V power supplies.
  • Adjustable output power distribution per port, input power current limiting and low voltage cutoff settings to maximize performance while also protecting the charger and input power supply.
  • Future firmware updates can be downloaded for free from www.ThunderPowerRC.com when new features, battery chemistry and other updates are made available and are easily uploaded to the charger using a standard mini USB cable.
  • Full industry-leading 2-year warranty and support from Thunder Power RC.

My new favorite charger in the whole wide world! Beg, borrow, or steal the money to get this thing... you'll love it! I have had an ICE, MRC's, Hyperions... on, and on, but this is by far the easiest to use, most powerful, versatile charger I have ever had the pleasure of using. I want another one just because I'm scared they will stop making it!

Nice, compact, easy to use charger with more power than most people need on a regular basis, but it's doubtful you'll find yourself outdated as your needs grow.

Have been using mine for over 3 years now. Only problem is that plastic on top of push buttons broke. Great charger though. You will not go wrong if you get it.

Excellent charger! It's charging my Thunder Power G6 2250mAh batteries in 10 minutes or less on a 12v car battery in the field. That's faster than I can use them if you consider the dual port capability.

Charger worked fine for 1 day and then 1 side stopped working. Ruined my race day. Called customer service but they did not have them in stock(2 weeks later still waiting). I wish powerlab would make a dual port charger, so I can ditch this thing, I have now read that a lot of people have had to send this charger back because they are not very reliable. Buy with caution. On the other hand the thunder power batteries are the best lipos on the market, just not charger.

The 820 repalced my 610 charger. Very nice upgrade. Very compact and lots of charging power. Ive had to send it in for warranty and software upgrade within 3 months, Im unhappy about that. Besides that, Im very happy and pleased with this product. I dont see myself buying another charger ever again.

i got to agree with everybody that this is an absolutely great charger! easy to use and plenty powerful when using a 24v+ power supply. it charges my thunder power g6 race packs in about 18 min.
David Cox
Excellent charger, simple to use, compact and powerful, should be the last one i ever buy. You will need a 27 volt power supply to get the full 800 watts though.
