INTRODUCTION
The TP820CD is a powerful and advanced dual port multi-chemistry charger, discharger, cycler and
balancer system. 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 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
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 powerful 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 3.5C, 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 (IR) 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 with industry-leading warranty
support and service.
