Nath89 Posted June 4, 2016 Share Posted June 4, 2016 Hi, new to the forum. Not very clued up with batteries so thought I should seek advice from the more experienced. . . . So which batteries are going to be best for this mod combined with Aspire Atlansis v2 running either 0.3 or 1.8 equally. Thinking I need a general all rounder? :/ Cheers Sent from my SM-G930F using Tapatalk Link to comment Share on other sites More sharing options...
FXRich Posted June 4, 2016 Share Posted June 4, 2016 (edited) I personally have a preference for the LG HG2 batteries, other people may have a different choice. They are a good 20A battery with a 3000mAh capacity, and work well with any tank, including the subohm tanks. Always buy from a reputable dealer, and never buy batteries off of ebay.

Nath89 Posted June 4, 2016 Author Share Posted June 4, 2016 Thank you for the reply, I was just about to edit. . . can you suggest any reputable retailers for these. Sent from my SM-G930F using Tapatalk Link to comment Share on other sites More sharing options...
jasonculp Posted June 4, 2016 Share Posted June 4, 2016 (edited) I agree with @FXRich I really like the HG2 or the Samsung 30Q. Before I make too many suggestions, I should let you know that it really depends on the Wattage you run it at. Your coil resistance has little/nothing to do with the draw on your battery. The Wattage/Joule setting determines how much amperage you are pulling from the battery. If you are running it at full capacity (200+ watts) I recommend you not using anything other than: LG HB2, LG HB4, LG HB6 They won't last long, but will be the safest choice. If you are running 150 watts down to 100 watts: Sony VTC5A (not the VTC5) Sony VTC4 LG HD2 Less than 100 watts: Samsung 30Q LG HG2 Samsung 20R LG HE2/4 I would buy them from one of the following: http://www.illumn.com/ http://liionwholesale.com/ http://www.rtdvapor.com/ https://101vape.com/ Here is a great chart for batteries: Edited June 4, 2016 by jasonculp Tam and FXRich 2 Link to comment Share on other sites More sharing options...

jasonculp Posted June 4, 2016 Share Posted June 4, 2016 I think I should also add that I personally would not run any 2 cell device over 180 watts. This is 90 watts per cell. 90 / 3.2 = 28.125 * 1.1 = 30.9 Amps. Link to comment Share on other sites More sharing options...

Only if it is mechanical. If it is wattage or TC the math works out the same. 180 / 6.4 = 28.125 * 1.1 = 30.9 Amps Your voltage is doubled on a series mod but your amperage capacity is averaged. With a parallel mod your voltage stays the same but amperage is doubled. Either way we are only asking for Wattage out of the batteries so: 100 watts: 100 watts to atomizer with a .5 ohm coil is requiring the board to supply 7 volts Parallel batteries at 100 watts have a low cut off of around 3.2V (on most mods) in order to supply 100 watts it will take 31.25 amps to supply it. An "average" board is only about 90% efficient so we add 10% so it takes 34.375 amps total. In a parallel circuit it divided equally between the batteries or 17.1875 amps each. (100/3.2 x 1.1)/2 In a series circuit at 100 watts with a low cut off of around 6.4V (voltage doubled in a series) in order to supply 100 watts it will take 15.625 amps to supply it. An "average" board is only about 90% efficient so we add 10% so it takes 17.1875 amps (100/6.4 x 1.1) Sorry, I am sure that is clear as mud....

Squid Posted June 5, 2016 Share Posted June 5, 2016 (edited) Thanks, I'm no electrical engineer but your explanation makes sense. Edited June 5, 2016 by Squid fat fingers, small keys on phone Link to comment Share on other sites More sharing options...
Nancy_Miller Posted October 15, 2016 Share Posted October 15, 2016 Sorry, I am sure that is clear as mud.... Thanks for good and reasonable explanation. I hardly consider myself as a completely dumb, but all this physics and electrics frighten me a little bit, a nice example is always good to understand the subject in question. High drain batteries http://gypsyvapes.com/batteries-E-Cigarette-vape are good to me, they surely can provide enough amps for a long time. Link to comment Share on other sites More sharing options...
