Okay lets clear some things up.
1900 amps is not 1900 amps at all, its 1900 milli amp hour. Its a engineering made unit of Amps per Hour (A-h).
Here is a quick formula V=A*I
V is Volts
A is Ampers
I is Resistance
think of it like a river, Volts is the flow, Amps is the size of the river, Resistance is the beaver who has put is bloody Damn in the way.
Thats why when you look at your power pack for an electrical device, it will show 12Volts at say 0.5amps aka it has a low draw on your supply.
you could have 12 Volts but 3 amp draw, the river is still flowing at the same speed, but its 6 times larger. more water will pass the point.
So your 1900 amp battery packs are only 19 amp hours (quite small).
depth of discharge will determin life of the battery pack. as a rule of thumb 50% is what you should be aiming for. so your 19 amp hour pack just became 8.5 amp hour.... a eq6 has a rating of 12Volt at 2amp, but thats during full load and slew. on average it will pull about 0.5amp.
Theoretically at 0.5 amp it will consume 0.5 amps every hour of use.
8/0.5=16 hours and hence why they are fine for just your mount. add anything else onto the system and you will be dissapointed.
On the other side of the coin, your paying 130 dollars for 19 AH, for a 105 AH battery im paying 230 dollars. it runs everything i own for a compleat night eg from 6pm to 5am cameras (2x) mount, laptop, dew heaters if required, I only use 40% of the battery.
So my advice to you. look at your battery packs of everything you are going to be using, a simple addition of those amp draws. double that number and add 15%
Capacity required= the sum of all device amp draw * 1.15 * 2
then go out and find the battery that is suited for your situation.
That is what you need to know in a nut shell.
