Hi Mark,

I don't have any of the TP820CD chargers yet to play (should be another 7-10 days) with but here is the data sheet released by Thunder Power. Basically, it is has 2 output channels each capable up to 400watts (at 26V input) and 1S-8S packs. You can combine both output channels together and charge up to a 16S pack so a hard wired 10S pack can be charged with the TP charger. Discharge is limited to 10 amps so that is 1/4 of the rate of the Power Lab. It looks like a nice improvement over the older 1010 charger with higher output and 2 output ports and balance charging. The balance adapters accept both Thunder Power connectors and JST-XH which are the Zippy/Rhino/Hobby King type. Another good option for sure.

TP data sheet:

The all-new TP820CD is the first ever dual port and the most anticipated, most powerful and most advanced multichemistry
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! 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 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 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
