No balance board!?

For such an expensive charger to not include a balance board is pretty sub par in my opinion. There is not even one for sale on your site! I am disappointed af rn. Buyers beware if you plan to use this charger for 6s+6s charging you will need to look elsewhere for a balnce board. I was expecting one in the package but I was wrong.


Awesome product. Needs a manual.

ICHARGER X12 from BuddyRc

I received the charger quickly as always from BuddyRC. I am a return customer and rely heavily on BuddyRC for several items such as motors. The Icharger works as described and appears to be a next level intelligent unit. This will be supporting a giant scale airplane build with a custom 12s battery. Looking really good so far.

Absurdly powerful

I haven't tested this charger to its limits, since they're so absurdly high... but I have pushed significant current and watts through it, and it doesn't even break a sweat. I haven't yet had the fan come on; temperatures stay low. The interface is a bit clunky with the single dial, but you get used to it. Incredible piece of technology.

Cool little unit

Amazingly small for its rated output (which I have not tested the limits of, yet). But very cool. Lots of battery types supported out of the box, good programmability, lots and lots of options. Reports pack level, plus individual cell voltages, mAh, and IR. Looks like it will be a great, much less expensive companion to my PL8.

The iCharger X12 is a powerful Junsi product that was launched in fall of 2020. Despite its miniature frame, this palm-sized charger can deliver an incredible 1100W 30A of power, making it perfect for charging up to 12S LiPo batteries. It is also packed with features that are typically only found in advanced chargers. The X12 shares the same easy-to-use interface as the popular Duo iChargers. Buddy RC has been a leading iCharger distributor since 2009, and we are known for our unparalleled service to iCharger users in the RC hobby community.

Special Features:

  1. The X12 supports a wide range of batteries, including up to 12s LiPo, Lilo, LiFe, LiHV, LTO, and NiZn batteries, with a maximum 2A balance current. It utilizes a unique balance calculation with internal resistance correction.

  2. Intelligent fan control. The internal temperature sensor detects the internal temperature, allowing the charger to control fan speed.

  3. Internal temperature protection. The output power is automatically reduced when the internal temperature exceeds the power reduce temperature, and the charger will shut down when the temperature exceeds the shut-down temperature.

  4. This charger can save 32 parameter settings and support data import/export to an SD card.

  5. A 2.4" IPS LCD screen provides rich information, including current, voltage, power, capacity, internal resistance, control status, time-consuming, and temperature.

  6. Multi-discharge features: self-discharge, regenerative to input discharge, and lithium battery extra expanding discharge.

  7. Supports measurement for internal resistance of batteries both offline and online. It can measure not only the internal resistance of the entire battery pack but also the internal resistance of each cell within the lithium battery.

  8. The X12 has protection for reverse polarity, input, or output.

  9. Supports software updates via USB port or SD card. The X12 also supports the “Junsi Console” software, which displays, plots, and analyzes the charge and discharge data.

The X12 comes with a one-year manufacturer warranty handled by Buddy RC, a major iCharger distributor since 2009.
