The Venom Pro Duo AC/DC LiPO & NiMH Battery Charger features a monolithic vertical stance and saves valuable bench space by providing two complete charging circuits, each with its own dedicated 80W integrated power supply in a footprint equal to most single charger solutions. Having two dedicated power supplies in one compact package means both channels are able to receive 80W of power, ensuring you are not diluting your amp rate when charging a second pack.
As an added bonus, you will not need to haul that separate power supply out to the track anymore. Menu navigation is easy using the five-button control interface and brightly backlit LCD screen. All the most common battery chemistries are supported: LiPo, LiHV LiFe, Li-Ion, NiMH, NiCD, and Pb (lead acid) with a complete assortment of charge leads included in the box with two extra long balance leads to make safe charging in a LiPo sack effortless.

I was puzzled why I could never charge LiPo batteries for storage at more than one amp. I worked around this by balance charging my 5,000 mAh packs at 5a for 20-30 mins first to get them close to storage voltage.
It was annoying that the left and right sides of this charger are basically two separate chargers sharing the same display. If I created a program to charge a specific LiPo battery on the left side, it wasn't available on the right so I manually had to create the same program there.
After a few dozen packs the fans started having troubles, a loud grinding sound when first charging that would eventually settle down. This grinding lasted longer and longer, affecting both fans, until one fan died entirely. The Venom warranty is absurdly short. "Venom Group warrants all products to be free of material and workmanship defects for a period of 30 days* from date of purchase for all electronic components." Having replaced fans on RC cars and PCs I was confident I could replace the faulty fans here myself. However, the assembly of this unit made it virtually impossible to not destroy the front panel buttons when attempting to separate the halves of the case to access the fans.
After my experience with this charger, I'll be looking for a replacement from another manufacturer.
