This is the Thunder Power TP820HVC LiPo/LIHV/LiFe/NiMH Dual DC Battery Charger. The TP820HVC is the first ever dual port and the most anticipated, most powerful, most advanced multi-chemistry charger, discharger, cycler and balancer system and safest for high voltage LiPos and standard LiPos from Thunder Power RC. With up to 800 watts of total charging power, nearly 4-times that of the ever-popular TP1010C, the TP820HVC is equipped with two ports that function completely independently to charge, discharge and cycle a wide variety of 2-7S HV LiPo, 1-8S LiPo 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/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 most other batteries.

The dual port TP820HVC 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 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 TP820HVC is well-equipped to quickly charge batteries up to 8S on each port for use in series as up to 16S in large-scale airplanes and helicopters. A popular example of the incredible charging capability is the ability to charge two 6S 5000mAh batteries, one on each port simultaneously and with maximum input voltage and power for ultimate efficiency, at just over 3C to have a complete 12S 5000mAh battery setup charged in as little as 20 minutes or less time. 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.

Other great features include built-in data logging, viewing and internal resistance measurement, 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 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 backed by Thunder Power RC’s industry-leading warranty.

NOTE: This charger is LiHV compatible, but will only charge Thunder Power brand LiHV cells to high voltage specifications. Compatible Thunder Power LiHV batteries and LiHV chargers have an extra pin in the balance connector that will prevent any other brand of LiHV battery from charging to LiHV specs. It will charge standard LiPo batteries and non Thunder Power brand LiHV batteries to a maximum of 4.24V per cell.

First of all I want to say I am a BIG fan of Thunder Power`s products. I have 2 chargers, 4 batteries, and numerous motors made by them. My current charger ,TP820CD, I`ve had for about 5 years and it has worked flawlessly. What I have just learned about their HV charger is that it only chargers HV batteries made by them!! It is not compatible with Orion batteries and I suspect any other maker`s batteries as well. It seems, in TP`s wisdom, that they put an extra pin on their balance connector so that the charger recognizes that the battery is an HV. Again unfortunately, at this moment , Thunder Power does not make any Surface use batteries in HV !!!! Great charger but no batteries…….
But having said these negative words I am sure they will have a hard case in the future and I can`t say enough good about the charger other than what I`ve stated. Thunder Power`s products are great.
$99 is a GREAT price for this dual,high power charger, with HV . But if HV is your gig, I`d wait to see what the future holds. Extra pin or no extra pin….

I wouldn't buy anything from this company. They are thieves! They treat their customers as if they are dollar signs and nothing more! There charger not only cost me many expensive lipo as it killed them, the company admitted to me the software was responsible,which is a an MFG defect, they asked me to ship the charger to them so i paid to do that then they wanted me to buy another one of their chargers, no way! now they want more money from me to ship it back, not one more penny to Thunder Power! they make American RC companies look bad! Many people are complaining about their chargers and i met a guy who had one of their lipos blow up in his hand! causing severe burns! As RC enthusiasts its our responsibility to make sure companies like Thunder Power go away! we dont need companies like these picking our pockets and making the hobby look bad.

just wondering if the guys above were charging regular lipos on the lihv setting be accident? which charges each cell to a higher voltage.

I purchased this charger based on the bang for your buck factor. The specs were too good to pass up for the price. That's where the positives end.

The first charger was dead on arrival. The second port was not being detected by the charger software. A quick chat session with Amain and I had a return label in my email ready to ship back.

Couple of weeks later I received my replacement charger. On my first use, I charged two 4S batteries. The charger over-charged 2 cells to 4.29 volts each. Luckily I caught it before any more damage was done.

This is not a quality charger with software issues that allow it to overcharge LiPo batteries. I ended up returning it back to Amain for a refund.
