Ashida
I'm having problem which I can't turn on my trimmed wii with battery power. It only will turn on when I leave it charging for a long while and when it turns on (with the charger connected) RVLoader says the batteries have 18% charge. Even so, when I try to turn it on without the charger, it doesn't turn on. I don't know if it is the charger I am using or the batteries itself. I tried 2 differen usb ct chargers, one being a phone samsung charger, and a lenovo thinkpad charger. All of them couldn't charge the batteries.
The batteries are 21700-50E li-ion batteries. The power board used is the rvl-pms-2 conected to a pms pd3.

I have the same batteries and my ashida work good since 2 month.

What is the voltage of your batteries ?

The pms will not turn on if the battery voltage is less than 3.5 3.6 volts
