I wanted to know if the battery is 6800 mAh is compatible with this monitor system and camera. (
I do not know if 6800 mAh is too much)

Another doubt is how I could record my shots?
thank you guys.

I’m thinking those are junk batteries..
4 good quality 18650’s and charger for $7 bucks..does not exist.
My guess, those cheap blue Chinese batteries that claim to be 5000ma…
They lie! Absolute trash
The one in the top post is not bad at all, Im’ sorry I spoke to soon..I’m not familiar with that one..
This is the one I was thinking about…
Can u find link to batteries
Even being made from cheap products, everything worked very well. Can identify animals clearly up to 30M, such as birds and mice.
I used very little of it, as I already said the batteries burned in the charger.
I will order a single 12v battery like the one I already put in the first post.
When I have a decent mount and batteries I will do a review.
(Can anyone show me a way to fix the camera on the scope in a way that to make adjustments?)
The shopping list. (The TV monitor and The cables/adapters I bought in Brazil)

Sorry for the delay in answering.
Things are complicated here in Brazil.
First: I built my night vision! Works seemingly well. I tested only once with 3.6V 9000 mAh batteries. Then I went to recharge the batteries and due to the poor charger they stopped working.
I bought everything by aliexpress, and the system works very well up to 30m.
When I have time I will do a review.
I’m just having trouble making a camera mount if I fix it on the telescope.
Thank you Mrnewbie, you helped me with your imbox messages.
Sorry for my english, google translator rules. :whistle:
Sorry to chime in a little late, but might help others with the same question.
What needs to match on all your items that are connected to the same battery is the Voltage, in your case 12V (monitor rating, camera rating and battery rating).
If one doesn’t match, it will either not work (e.g. Battery 6V, camera 12V – camera won’t switch on), or work for (very) short time only before being destroyed (e.g. Battery 12V, camera 6V – camera will blow up).
The Amperes or Miliamperes (which is 1/1000 of an Ampere) practically translate to how long the setup will work, the higher the Milliampere rating, the longer time your setup will work before the battery is empty.
Cheers
You found the correct forums for such things..there is a wealth of info on nv stuff.
The Cmos camera..its a turd..don’t do it.
The NV uk forums will tell you to get the KCT E700..it is one of the best out there for around 70-100 bucks.
If you need to be budget, or only need to see 100 yards..then go with an Effio V…40 bucks. Or any HAD CCD II sensor camera is better than Cmos.
Search JAX on the forums he came up with a cheap 100 buck build good out to 100+ yards for around 100 bucks.
The screen…this is cheaper and higher resolultion…

The battery is fine…
I found this forum that took almost all my doubts.

for good 18650 cells…go with LG or samsung sourced….they are the best…..if you want cheap 12v just grab a battery from the local RC hobby store…3S lipo = 11.1v to 12.6 well within specs of most 12v systems which are rated for 12v car batteries which while being charged can be as much as 15v
MAH = is the size of your fueltank a 6800 mah battery should last 1hr if your draining with 6.8A (which you are not) your more likely to be using about 1A max and in that case it will last 6.8 hours !
1 lipo cell =3v to 4.2v depending if empty or full ! so a 3S (3 cells inside pack) would be 9-12.6v with a mean voltage of 11.1v
18650 out of china is a lottery, i got 2800mah cells that are more like 2900 cells……i got a flashlight not long ago with 3500mah batteries…however these are about a third of the waight of my lg and samsungs…and once on the discarge unit it turned out they where more like 1200mah…total bull shit…also they could not handle even a 2A discharge. my best LG takes a 20A discharge delivering 2400mah just as rated, and they do this without getting more than luke warm
i took a lens from my security cam (no IR filter) and put in my fpv camera with 200mw transmitter, added a 3w IR LED….i have fatshark fpv googles….i just gotta mount it up behind the eotech, and i am good to go with wireless headmounted display
