Everyone has the problen with Xmiter
batterys. So I made a pigtail outboard
to charge the main battery slow about
250 mil while I am flying nothing like that
beep to scare you. I use a small 12volt with a restor to limit the current and watch the voltage on the Xmitter for voltage and with a switch shut it of when
charge. Of course I fly my elec more than
normal maybe a hour at times. CU
