alenK Posted June 7, 2017 Report Share Posted June 7, 2017 Hello, I am thinking about power supply distribution etc. and considering how the popular distribution splitter boxes use 6 Amp Polyfuse Thermistor overload protection. I was curious to learn what the overload spec on the batteries I use. I looked up some specs. IDX NP-L7S 14.4V Lithium-Ion NP-1 Battery (68Wh) : Maximum Discharge Current = 4.8A/53W with Battery Protection: Over charge, Over discharge, Over current, Temperature. Sony BP-GL65 14.4V Lithium-Ion V-Mount Battery (65Wh) = could not find any information at Sony Pro I previously owned a camera system and when its technology was rendered worthless the V-mount batteries retained good value so I have been using them as the primary power in my bag kits. Does anyone know what the maximum discharge current for the Sony BP-GL65 14.4V Lithium-Ion V-Mount Battery (65Wh) is? I can not find a published specification. Thank you.

Jim Rillie Posted June 7, 2017 Report Share Posted June 7, 2017 I would think, probably about the same as an NP-1, unless the chemistry is quite different. Maybe about 10% higher. Quote Link to comment Share on other sites More sharing options...
chrismedr Posted June 7, 2017 Report Share Posted June 7, 2017 the sony manual says that discharge over 2A can result in degrading the battery over time, and that at a peak current of 10A it will trip the internal fuse to prevent damage: https://www.sony.de/pro/support/attachment/1237485697471/1237485596017/operationmanual.pdf?token=zwDagU0F_nA0YDYylwwswcudX5ixl3CYHgiCYaqOHIO_WaVVm6SLJsQ9XcvgxhiN6AOY9x7ZDJATF_zVmlY3EmQgdxeWUSTUnOv7MX78uvhTS3oZ Quote Link to comment Share on other sites More sharing options...
