Using V-mount battery to power Led Lights like Yongnuo YN600 8volts 5amp DC input?

[analogs]

I have a V-mount Plate that has an 8v out, but I think the amps on those plates are 2amps.

The V-mount battery I have is a 198Wh/13400mAh.

Is it possible to get a D-tap to 8v DC cable that can handle 5 amps for my led lights or are most of these cables usually for 2 amps use?

Any recommendations on how I can use the V-mount battery to power these types of portable led lights that usually require 8 volts at much higher amperage greater than 2 amps?

I was considering using Dtap to Npf adaptors cables but the light requires 2 Npf batteries which will just add too much cabling and adaptors for my use.


Thank you.

The watt/hr spec does not indicate an ability to deliver amps .. or that wattage for an hour

Many voltage converters on Amazon eBay if you can make or get cables made

Over the years for oddball power supply requirements, I've used "Buck" converters. Just mount them in a Jiffy box which you can buy from most electrical hobby stores. This will protect the Buck converter unit. An alloy Jiffy box would be best as it will act as a heat sink. Voltage conversion at higher amperage will generate a bit of heat. A Buck like the one listed below would do what you require. Using these types of units I just go straight from the D-Tap on the V-Mount battery. A Buck converter will auto-range on input so as your V-Mount drops voltage the output voltage and current will remain constant at whatever levels you have set the output to. Output voltage adjustment is via press buttons. Set it to 8 Volts and it will deliver 5 Amps if that's what the draw is. Just a minor amount of simple in/out cabling is involved at the terminal clamps. As I said stick it all into a Jiffy box and it's all pretty well protected. I've built small neat camera and lighting power supplies using these sorts of converters.

Thanks all for the tips! I forgot these step-down converters are available with higher amps.

There's also plates like this one available:

I had a Tilta plate similar to this that I've use with my FS7 - and it was great to power camera, small monitor, and wireless transmitter all with one v-mount. Think I also used it a few times for follow focus motor. Just ordered the small rig as my Tilta has a bit of play with some of my v mount batts - which suddenly means a tap or bump of battery shuts down everything - which could have been disastrous - but thankfully only happened once - while setting up.
