Has anyone attempted to use a generic 12v battery to power a nikon D700 through the grip.I have a spare 12v lithium battery from a power drill that the brushed motor broke.The grip can hold up to 8 x AA batteries. AA batteries can have a voltage of 1.5 volts, so 8 * 1.5 = 12v.In theory it should work.But I'm afraid to test and destroy the camera.So, I'm asking if anyone has tried this before.
>>4514800yes and no. If your power supply is strong enough, just match the voltage. AA batteries are rated between 1.2V and 1.65V so anything between 10v and 13V will work. 12V is just the nominal voltage. No worries anon. Just make sure your external power supply can provide enough amps otherwise the voltage will drop and if the device isn't protected (it is) it'll turn off in the middle of doing something important and have problems or just die. For your Nikkon the max amps is about 2A (super low) so basically any lithium battery will work, but if you want to double check, just read the rated continuous discharge of your battery (the C) to know how many amps it can deliver (it's different from the battery capacity with is given in mAh). >t.

>>4514841just two notes :1) make sure the polarity is correct 2) lithium batteries themselves are rated at a range , I doubt your battery has a regulator inside that forces the output to be 12v. But anyway the range is similar to AA batteries so no pressure
>>4514800Your "12v" pack is actually 10.8v; provided the grip can work with Ni-Cad/Ni-MH batteries, which would only generate 9.6v, it should be fine. Be sure to check the polarity, as the one Anon said.
