1 The 308DUO uses advanced Synchronous buck-boost DC/DC converter technology, high power, a high current and high-performance power conversion circuit. The maximum charge power capacity is up to 1300W, the maximum charge/discharge current of a channel is up to 30A, and two channels in Synchronous Mode are up to 50A.
2 Each channel supports 8s LiPo, Lilo, LiFe and NiZn batteries, with maximum 1.2A balance current, and adopts a unique balance calculation of internal resistance correction. Supports 1-20s NiMH/NiCd batteries and 1-15s Pb batteries..
3 With 1A/5V USB charging port, convenient for the user to charge mobile phones and PCs.
4 When the channel output connects the battery after the charger powers on, it will start automatically the anti-sparking protection.
5 Intelligent fan control. Sensing internal temperature via the internal temperature sensor, to thereby control the fan speed.
6 Internal temperature protection. When the internal temperature exceeds the Power Reduce temperature, the output power is automatically reduced; and the charger will shut down when temperature exceeds the Shut-down temperature.
7 This charger can save 64 parameters sets and supports the data import/export to SD card
8 A 2.8-inch LCD screen provides rich information including current, voltage, power, capacity, internal resistance, control status, time-consuming and temperature, etc.
9 Multi-discharge features: self-discharge, regenerative to input discharge, and lithium battery extra expanding discharge.
10 Supports measurement for internal resistance of battery offline and online. Can measure not only the internal resistance of the entire battery pack, but also measure the internal resistance of each cell within the lithium battery.
11 The iCharger has protection for reversed polarity (input or output), input voltage/current, battery temperature, charging capacity, overrun time and maximum power etc.
12 Supports upgrading the hardware program by USB port or SD card. The iChargeralso supports the “Logview” software and can display, plot and analyze the charge and discharge data by it.

Lots of options you can configure, and works great with a resistor back I built to use with it.
This is my second 308, lost my first in hurricane ian. Worked perfect for years. So of course i wanted new one. I sure will work for many years.
This charger Is very compact in size but has plenty of power to get the job done. I run two of these little chargers off a Junsi S1200 power supply and have no problem keeping my 6S 5000s, and 12S in synchronous mode, charged up and flying. Screen displays all cells without having to scroll. Transferred all my presets from my first charger via SD card, so setup was a breeze. I definitely recommend this charger.
I've own three of these iCharger 308 Duos since they were released in 2013. I believe the iCharger Duo series chargers introduced this fancy tilting color display to the hobby. There are several other chargers now with color displays, but none of them tilt like this one and the rest of the iCharger Duo series. I have never had any major issues with these chargers over the past 8 years that I've owned them. They have been very reliable. I sold one of the three iCharger 308 Duos, as I was not using it, so I am down to two. After 8 years of ownership, I decided to check on voltage calibration with a Fluke 87V digital multimeter whose calibration was tested against a voltage PentaRef. The individual cell voltages where off by as much (or as little) as ±0.007V on both units I still own, which I find to be very acceptable. I still adjusted the voltage calibration, but I cannot say it was absolutely necessary to do so.
I like how these chargers allow users to set presets. Setting presets is a bit cumbersome and time consuming as it uses a scroll wheel. However, for me that I own more than one charger, I was able to save all the presets of one charger into a microSD card, and load them onto the other charger, which saved me a lot of time and effort.
However, as good and reliable as they are, they are starting to show their age. There is no WiFi or BT connectivity. There is no phone/tablet application. The charger does not save individual battery data. There is not safety warning to alert the user if the user inadvertently mismatches the charging wires from one channel with the balance wires from the other channel.
I recommend this charger, but I recognize it is dated.
I am looking forward to using this charger. Being familiar with Nitro and Gasser only, my friends recommended this charger for my first and future 12s 5000 mah model setup. They had nothing but praise for the iCharger 308Duo.
Nothing can beat this charger, very convenience with pre-set for each kind of battery, and very accurate balancing!
Awesome charger, great features easy to use with a bright display
All of important info provided on screen while in use, a must have for everyone
There are many different choices for chargers. The iCharger 308 DUO is the best dang charger out there. It will charge and balance all of your batteries with no issues, if you plug something up wrong it will let you know, and it charges all the way to 8S lipos at 30 amps! I fly 6S lipos and I have never kicked it up that high. The highest I got was 10 amps per channel 20 amps total... it just kept on charging! I love this charger and so will you!
Great charger with plenty of features. Also cut my charging times in half.
Ive always use the icharger and been great so far. I like it so much I bought another one for a back up charger setup.
