iCharger 308Duo 2-port Battery Charger

iCharger 308Duo LiPo Battery Charger

My current main charger is the iCharger 308Duo. The 308Duo uses a synchronous buck-boost DC-to-DC converter with a charging power of 800W/30A per port (Asynchronous mode) or 1300W/50A with the two ports combined (Synchronous mode). Since this is a DC input only charger, I’m using two Hewlett Packard DPS-1200FB 12VDC 1200W (700W at 90-132VAC) computer server power supplies in series to supply 24VDC at up to 1400W for the 308Duo. Like most iChargers, the 308Duo has internal resistance measurements that allow you to keep an eye on battery condition. Software in the 308Duo can be updated via memory card or USB cable, and the latest version adds the new high voltage LiHV feature, at no charge just by updating the software. This has been an outstanding charger and setup with plenty of current for charging multiple LiPos in parallel.

Other Chargers
I also have two other small inexpensive chargers (Venom Pro and Thunder AC6) that I run from the HP power supplies along with the iCharger 308Duo when I need to charge additional batteries or smaller 1S or 2S batteries at the same time. With this setup along with various parallel charging boards and parallel charging cable sets, I have charged 12 batteries, 4 sets of different size and cell counts.

Previous Chargers
Prior to switching to the iCharger 308Duo, I purchased a Hitec X4-Eighty 4-port DC charger with a Hitec ePower 12VDC 30A power supply but had many problems with the X4-80 charger so I sent both back. The ePower 30A PSU worked okay.

Prior to the Hitec X4-Eighty I was using a Dynamite Passport Duo 400W (200W, 10A X2), which was a great AC/DC charger but lacked the output power to charge multiple LiPo batteries in parallel.
