Hello everyone,

The first shipment of TP820CDs has arrived and the many, many backorders have been shipped out The second and third shipments will arrive in the next few weeks.

Here also is some additional info on the TP820CD:

Overview:

The all-new TP820CD is the first ever dual port and the most anticipated, most powerful and most advanced multi-chemistry charger, discharger, cycler and balancer system from Thunder Power RC yet! With up to 800 watts of total charging power, nearly 4-times that of the ever-popular TP1010C, 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 and NiMH along with 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 all-new Thunder Power RC exclusive 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 ‘split’ 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! And be sure to compare these ultra-fast charge capabilities in addition to max charge current and wattage output because that’s 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 (expensive) power supply, and without giving up the added convenience and flexibility that independent dual port charge, discharge and cycling functionality offers. And 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 download from http://www.ThunderPowerRC.com using a standard mini USB cable. Best of all these incredible features are all available at a value that’s hard to beat while being fully supported and backed by Thunder Power RC’s industry-leading 2-year warranty. © 2011 Thunder Power RC

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 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* – 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 http://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

Adaptable Balancing
The built-in LiPo/LiIon/LiFe (A123) cell balancers and included balance connector adapter boards are readily compatible with all 2-8S Thunder Power balance connectors and the JST-XH balance connectors found on many other batteries.

Capable Connections

Separate main power and balancer connectors allow for simultaneous charging and balancing at charge rates up to 20 amps on each port while the programming connector can be used with a standard mini USB cable to install firmware updates.

Maximized Protection

The dual ports function completely independently, and with adjustable output power distribution, input power current limiting and low voltage cutoff you can maximize performance of each while also protecting the charger and power supply.

Thank you and best regards,

Thunder Power RC

I just finished my article on finding a power supply for the new big chargers. It is not 100% perfect just yet but I hope it gets the point across.

Hello Nas,

From the TP820CD manual (which will be available for download from our web site soon) regarding Power Distribution:

<SNIP>

For example, with an input power source that supplies 12V and 30A max under load, if the Power Distribution is set to 50%/50%, the maximum wattage available from each port will be approximately 150W max (300W total). However, because each port is capable of up to 250W max with 12V input, you can actually bias the power distribution to give one port more power versus the other in order to achieve the 250W max for one and 50W for the other (achieving the same 300W total but with more/max output power capability for one of the ports). This is particularly useful if you need to charge higher capacity/cell count motor power batteries on one port and lower capacity/cell count motor power, receiver, transmitter, etc. batteries on the other port simultaneously.

Hope this helps!

Jason

Can these measure the IR of lipos with any accuracy? The pack as a whole and/or individual cell?

Not sure if I missed it. Hopefully Jason can tell us whether it measures total pack IR or if it measures individual cell IR as well?

Hello everyone,

The TP820CD can measure battery IR for NiCd, NiMH, Pb and of course LiPo/LiIon/LiFe batteries when the balance connector is not connected. However, the TP820CD can also measure individual cell IR when the balance connector is connected for LiPo/LiIon/LiFe batteries.

We also continue to work toward 'optimizing' the IR measurement values for individual cells. Our goal is to ensure the TP820CD measures as close as possible to the lab-grade and calibrated equipment we use to measure cell IR now for R&D testing and matching before battery assembly. We’re already very close for the entire battery (much closer than other chargers/devices in the market), as checked through the main power leads/connector, but there are a few more variables when checking through the balance leads/connectors (because they’re higher resistance than the main power leads/connector and vary per make/model of connector, crimp quality, etc).

These details in mind, V3.1 firmware for the TP820CD (as included in the first shipment) does an excellent job of checking battery IR. Best of all it does so with the single push of a button and 1-2 seconds time....it is not necessary to charge a certain amount/wait a certain amount of time to measure IR. Instead you can check the battery IR in seconds immediately after charging or at any time without charging. The instruction manual also details how to ensure your IR measurement results are repeatable and relative from battery to battery, cell to cell, etc.

V3.2 firmware is in testing now with further optimized IR measurement for individual cells and should be ready next week. Hopefully it will be tested, finalized and ready in time to load into the second shipment of TP820CDs before they ship to us late next week (just before much of Asia shuts down for 2-4 weeks due to CNY), but if not it'll be quick and easy to download and install V3.2 firmware in all TP820CD chargers using a standard USB to mini USB cable.

And rest assured we are aware that battery IR measurement alone is not desirable for LiPo/LiIon/LiFe battery users, hence the reason we continue to work so hard to ensure the TP820CD measures individual cell IR as closely as possible to the equipment we've used to do so for many years now.

Also, for those that may be concerned about the number of screens a charger may have, please note that the TP820CD features a huge 48-character screen that’s more than twice the size of the screens on other dual port chargers. That means you see more data with less button pushes (because there are less screens to view/scroll through) and it takes only a single press of the ‘PORT’ button to switch between the rich data display for each port.

Please also keep in mind that Thunder Power RC already has a fully established service and support center in the US (and at various authorized distributors world-wide) that can repair (or replace) chargers as needed throughout the warranty term of a full 2-years and even beyond. For added reference we continue to repair (often at no charge for repairs such as replacing buttons/screens/etc.) TP1010C chargers that are upwards of 5+ years old helping to best protect the long-term investment made in a charger. This also means that beyond the warranty term you are not expected to buy a new charger, even at a discounted price, if something can be replaced in our service center.

Thanks,

Jason

Hello everyone,

Just a quick note to let you know that the latest shipment of TP820CDs has arrived and will begin shipping out on Monday! This means everyone that took part in the pre-order promo should have their charger mid to late next week and that all distributors and dealers should have stock available around the same time. BTW - these chargers include the latest version firmware and an updated (and extremely detailed) instruction manual (also, the computer interface to install and the new version firmware will be available for users that already have a TP820CD next week).

Thanks,

Jason
