Well worth a look are the Kentli AA Batteries, they provide long operating hours and eliminate the need for cables. Attachments:

Kentli are the leaders in batts for sure, if your not going the external route..

I got some Diall AA 2300 mAh rechargeable's from B&Q on Saturday, all for Ā£7.00 with charger, just to tie me over till the Kentli,s get hear.I also have a Anker 20100 mAh power supply that i use when using the WiFi. When pluging in the power supply the x-sight ask's weather i require "Power supply mode" or "Mass storage capacity mode". I have looked all over the net and in manuals,but have not found any mention of this. I have been selecting the "Mass storage mode", is this correct.

Hi Bestie
Choose the top option USB Power Supply Mode, you'll get around 20 hours run time using your external and I'd say around 2 hours from the rechargeables.

I ordered a set of Kentli batteries back in Dec of 2015. The still have not arrived. Track info is saying they are in Chicago in early Jan. 2016 and I still do not have them. How long is it taking to get them delivered on average does anybody know?

I have been waiting 2 months. The seller is sending another set. So another 2 to 3 week.

I ordered the KENTLIĀ® 4pcs 1.5v 2800mWh Li-polymer lithium rechargeable AA battery + 4 slots smart Charger on Amazon. $59 and I got it in 6 days including a weekend.

Always ensure you get the 2800mwh, as they also have less powerful ones. Also, remember you need the special charger for them, as they DO NOT charge through the nipple, they charge via a charging ring. The charge voltage is 3.7v, but discharge is regulated in the batteries via a built in voltage regulator to 1.5v continuous to very very shortly before the end of their charge The discharge ONLY is via the nipple, do not try to charge them in a normal charger, you could destroy them. They are not cheap to buy, but will pay themselves back in 3-5 full sessions of use

Just a note on KENTLI polymer lithium ion "2800mwh" READ the fine print. Pay attention to the fact that these batteries are rated in "mWh" (mili WATT hour) and not the more common "mAh" (mili AMP hour) According to my math P = IxV where P=watts, I=Amps and V=volts then 2800mWh/1.5volts = 1866.66mAh which is not any better than the 2500mAh Eneloops nickel-metal hydride @ 1.2V = 3000 mWh, which is readily available in the USA.
I use Uniross 2700 mAh batteries in my ATN XS2 which are also NiMH nickel metal hydrite @ 1.2V = 3240 mWh. Chinese tricks of the trade, but the real question would probably be 1.5V x 4 to give 6 volt or 1.2 x 4 to give 4.8 volt.

Yes, but the Kentli 1.866mah is at 3.7 volts delivered at 1.5 volts so you are effectively doubling up. And they give , whereas the Panasonic is 2500mah at 1.2 volts, and it's the voltage drop off that is actually the big problem, meaning the Panasonic stop supplying enough at around 3-6 hours (depending on what optional S you are using) whereas I got 12-14 hours out of my Kentli on the X1 i think the 1.866mah (2800mwh) is what it produces at 3.7v so at 1.5v (which the Kentli deliver right to the end) you would be getting around 3.8mah at 1.5v (I think) although you will lose some due to the voltage converter. We have tried every battery going, and NOTHING has beaten the Kentli in an AA package till now

Reddich, I believe you are correct with the 1.8mah at 3.7v and then 3.8,mah at 1.5v, although you would probably lose .8mah to the converter. I wish I had a battery tester to actually find out and if they come close to what they claim. All that being said, I have two sets of Kentil and I've never had to change them out while hunting. I think being able to hold 1.5V to the end is what makes them so good. I just wish they were cheaper and easier to get.

Very well, the above finding was just off the top of my head, and I made a quick comparison to what I have for batteries. I would obviously be interested in the Kentlis since this is the first time I have heard about their existence. After having a quick look at the Anker battery pack and then as well the kentlis, I saw this at the bottom of the search: Evolva Future Technology T20 IR 38mm Lens Infrared Light Night Vision Flashlight Torch -To Be Used with Night Vision Device. This may sound a bit off topic but they offer the EVOLA 'smart battery' (again a first for me) here with integrated DC-DC converter circuitry. This means that it is actually high power (3.7V-3.8V) battery regulated down to provide 1.5V I researched the Kentlis further now and found this for those who what to pursue some technicalities and opinions.
By no means do I say I have better, in fact I want better, but as for these guys on this (linked) forum their chase to better batteries and the expenses towards them is in line to what we want here together. I found it quite interesting. I would also ask myself why are these batteries not so freely available in the US. Is it market manipulation or would it be not approved technology or are they regarded as dangerous. 1)http://www.candlepowerforums.com/vb/showthread.php?371189-Kentli-LiIon-AA-batterys-with-1-5V-regulated-outputhttp: 2)//lygte-info.dk/review/batteries2012/Kentli%20AA%202800mWh%20%28Blue%29%20UK.html

Although the Kentli are expensive to purchase, you actually start saving money after the first 3-5 charges compared to using throwaway Lithium, or having to have multiple packs of Nimh that you need to change out every 3-6 hours (and you can guarantee that prize animal you've been waiting for all night, will show up at the EXACT moment you've pulled the batteries out to change them, that's Sod's law)
Always remember to use the Kentli specific charger for charging the Kentli batteries. Failure to do so could result in damaging or destroying the Kenli batteries. The Kentli do NOT charge via the nipple, that's for discharging at 1.5v regulated only. They actually charge via a charging ring, and this is what the Kentli charger is designed to contact. Also, do not attempt to charge any other make/type of battery in the Kentli charger, that would destroy the charger

In the beginning, I bought two sets(of 4)of the top rated rechargeable batteries available. In the US, the 2,700 Mah PowerX and XXX batteries have held up well after a lot of field testing. Of course you'll need a good charging system and I found that the newer version of the BT-C2000 charging system is one of the best out there too. This combination has kept my scope working as well as it can and are readily available in the US.

The kentli suggestion was nails. Of course now I guard my AA batteries like a 19th century prospector on a claim

Hi,l I'm just starting with the X-SightII and have found my current rechargable NmH AA batteries are flattened in about 45mins! I see the information about the Kentli batteries but they only seem to be available shipped from China! Can anyone suggest where to get them in the UK or an alternative? Failing AA's that will give me at least 2-3 hours I guess I'll have to go down the external battery pack route. Thanks

I have a question that i hope someone can answer. I have a 20000mah battery pack laying around the house that i would like to use with my scope, the question is, is that it has two different outputs 1amp and 2.4amps. Which one do i use, can i mess the scope up if i use the wrong one?

Dfwfire, it should not matter at all. The unit will only use what it needs. My battery pack also has two outputs as well. Most of the time, I try to use the higher power port. I have not seen any change in run time...

We use Kentli AA batteries in a X-Sight II 3-14 with all gimmicks on. They last 3h 22m. We will try without all those and see.
