Where to buy authentic batteries

[Grrttbrooks]

My local shop only sells the efest batteries and that's fine in my box mod, but I was looking for a site that sells authentic Sony batteries to run in my mech mod and could someone tell me the difference between VTC4 and VTC5?

***update****
My friend told me this company sells authentic, but I'm just weary because of the cheap price. Can someone tell me what think also

Illumn is a very very reputable site.
They are very well known.
They are good to go.

Illumn is where I buy all my batteries from. Bonus points for giving you free cases when you buy em in pairs. RTD Vapor is also a pretty reputable site, as is Orbtronic.
Ive never ordered batteries from them, just many other things, but Lightning Vapes is also a good guy too.

the difference between VTC4 and VTC5?

Check out @Mooch (one of ECF's battery gurus) and his battery "bench tests".

• Sony VTC5 20A 2600mAh Bench Test Results...a good 20A cell
• Sony VTC4 2100mAh 18650 Bench Test Results...a 20A cell that can be used to 30A

He posted this yesterday:

"One of the most important things to remember when shopping for high drain batteries is...

• There are no 18650 batteries with a genuine rating over 30A! | E-Cigarette Forum

Here are the results of my testing six different high drain batteries at 30A...

The best batteries in these tests?
The LG HD2 or Sony VTC4."

Liionwholesale.com has great prices, fast shipping and only genuine cells...

RTDvapor is where I get my batteries and chargers from. Excellent service.

RTDVapor.com, illumn.com, orbtronic.com is where I buy mine. I have also heard good things about liion.com, but have never used then.
