Batteries and Charger for VTR?

[newdawn]

Been having a debate with myself regarding the MVP vs VTR and the VTR won in the end.  I'll probably buy from slowtech because the money saved can go towards new batteries and charger.  Just waiting to see if some of you finally got yours and they were legit before pulling the trigger.  Otherwise, I'll just buy it from myepack.  

That's all fine and well, except I can't get my head around batteries and they'd probably come in handy if I'm buying the VTR.  

Links to best (suitable) batteries much appreciated if any of you get a spare minute or two.  Thanking you muchly

I buy from them, they also sell the Nitecore intellicharger i2

Cheers


AND THEY ARE SAFE TO USE WITH A VTR.......The early VTR kit came supplied with one of these. 

Ignore Griff he's a northener..... Tease-smiley

The Nitecore is a good charger as it charges quickly and will take 18350, 18500, 18650 and others.

You want non protected 18650 batteries for the VTR, either 2000mAh or the maximum of 2600mAh.

There are many vendors selling battery chargers and batteries, just google "18650 battery chargers" and "18650 batteries".

I'd recommend a couple of Panasonic NCR18650Bs and a Nitecore i2.

I've a stack of 18650s and none measure up to the Panasonic one. Just got the Nitecore i4 and it's a great piece of kit.

Are the 3400 mah batteries  ok in them? I've been searching around, and a lot of people seem to be using them, in the VTR's.....
Griff's post with the max. 2600 mah, made me wonder..... barrynorton

I thought anything above 2600 mAh may damage the VTR as stated here. Just scroll down the page and you will see it red.

I got my first NCR1860B bundled with my VTR!

One of the early product demos, by Innokin, showed a NCR1860B.

[Griff]

My understanding is that Innokin informed venders who asked about battery mAh that they should advise customers that it is not recommended to use anything above 2600 mAh.

On that basis I am sticking with a maximum of 2600 mAh

[barrynorton]

I've exchanged a few mails with Innokin. I wouldn't derive too strong a conclusion from any of their vague and badly-worded answers. Did you actually see the reply? It didn't seem that much like advice against using something with higher charge. I'd also love to know by what electronic mechanism this could be dangerous.

[Griff]

I don`t think it is do with being dangerous, but on the life of the VTR with using higher than a 2600 mAh battery

Have you a link to the Innokin VTR demo video please.

The mAh rating will NOT make any difference! other than how long you can vape between charges.

As long as it physically fits and can supply enough current without falling below the minimum voltage it will be fine.

Hi, since we were referenced earlier, we thought we may provide our understanding (please be gentle, we are just trying to be helpful)

Through communication with Innokin Engineers we were informed to use batteries up to 2600mAh and have stated this on our page as such.
The higher the capacity of the battery, the higher the internal resistance of the battery. Increasing the resistance of one part of the regulator circuit (which the battery is part of) will change the characteristics under which the regulator operates that provides the supply to the MCU and other components with the VTR. This change may strain parts of the circuit as it has not been designed to operate in that range, which can eventually result in parts of the circuit failing.

It is true that the VTR will work with higher capacity batteries, but it is then operated out of the recommended / tested spec that we have been informed of.

This is not necessarily true though! Good quality batteries do not necessarily have higher internal resistances. You are more likely to get high internal resistances using a poor quality battery.

Excerpt from Wikipedia:

The internal resistance of widely used LiCoO2 batteries is higher than that of nickel-metal hydride, nickel-cadmium, LiFePO
4 and lithium-polymer cells. Internal resistance increases with both cycling and age. Rising internal resistance causes the voltage at the terminals to drop under load, which reduces the maximum current draw.

Therefore, if you use a low quality battery, it will age quicker raising the internal resistance.

[Deleted]

Agreed, low quality batteries age quicker, as the cells degrade faster.
We were referring to higher capacity resulting the electrons having to travel through more cells, therefore increasing the internal resistance of the battery.
