Reliable Vmount Battery

Great battery. Always reliable! Love being able to see the charging information on the built in screen. Great size and shape. My only complaint is the flappy port covers. They can get in the way a little but not a big deal.

Product was delivered on time and correctly. The battery had 28% charge when it arrived. I used a 140w Anker USB-C charger and a regular v-mount battery charger (not at the same time). Multiple USB-C cables were also used. Plugged in the USB-C and the code OT-UT began flashing. I held down the power button for a few seconds, the firmware number, cycles and watts screen came on, but a few seconds later the OT-UT screen began flashing again. I then tapped the power button a few times, the same thing happened. I discharged the battery and attempted to charge again. The same thing happened. I left on the charger for a few hours. Nothing changed. I needed if for this week and now I have an expensive brick.
