I have remove the solder of the balancer and fix them back, still the same. I can't send back to hana since I already remove the board. So frustrated spend 13 hours yesterday, have tried resolder, tried to change battery. Why is dna200 so fragile, i've been using dna20 for over 2years, and other 30 and 40 without any issue except of usb charging issue but dna200 is so so complex. Thank you for all that tried to think how to solve my problem, I really appreciate it and again, sorry for my improper english. I'll try to RMA evolv.
