iMAX B6AC B6-AC LiPo charger digital scale for Trex 450 RC Heli NiMH (Electronics)
Tested with my Lipo 2S 5000mAh, it works well, ok balancing (4.2 V per cell). No error message. Instructions in English but you can find French translations on the Net. Attention, the cable of power supply 220 is not in the French format. For my part
