Query: Great battery for price

The battery has been a really great affordable option to power my external monitor and my video light pannel. I shot a feature film using these batteries on the monitor and have shot many music videos as well. I highly recommend them. I have had no problems whatsoever in the 8 months I have been using them. I can shoot all day using 2 batteries on my 7" manhattan LCD monitor.
