The SWIT BN-S8823 7.2V Lithium Ion Battery from JVC is a 7.2V, 2600mAh battery that works with the JVC GY-HM100, GY-HM150, and GY-HM170 camcorders. The battery has a four-level LED indicator, so you can tell on sight roughly how much power remains before you attach it to the camera. The BN-S8823 is equivalent to JVC's BN-VF823 battery. The BN-S8823 also has a 7.2V pole DC output that can be used to power the SWIT S-2010 on-camera LED light and the camera simultaneously. When used with compatible camcorders, the battery transmits the remaining power percentage and recording time. An intelligent circuit protects against abnormal current, voltage, and temperature."
