Reading my post again, I can see why as I am not verbose or not as technical. So I will give my real world experience with RX200. With lower wattage RTAs, like modified Kayfun 4 with Monster V2 clone base, or a modified SKX Wine, at 18w I do not have to swap cells till 3 days later. With RTA running 40W, it lasts me the whole day. Compared to IPV4 as an example, I would swap cells at least once. Welcome to VT, btw. Link to comment Share on other sites More sharing options...

Series multiples Voltage... Parallel multiplies Amps/mAh Actually they all work the same in a Variable Wattage mod. In a series: 3.7V X 3 = 11.1V 200 watts / 11.1V = 18A since they are in series 3 batteries have the same continuous discharge rating. In parallel 200 Watts / 3.7 = 54 A , 54A across 3 parallel batteries = 18A Please note that I am calculating this at nominal charge. At cutoff voltage, your battery has to work much harder, so the amps drawn increases greatly. This is one reason I really like the RX200 so much. The triple battery really helps you have quite a bit of headroom, and the shape of the mod really makes it fit great in your hand. It is a bit heavy and bulky for my taste, so it stays on my table most of the time. Also I think I should note that the above calculations don't work with a mechanical mod. There are very few series mechanical mods, but there are some. In fact there is one that can use different battery contact bars so it can work either way. With a mechanical mod you must use the volts and resistance to come up with the Watts. With a Variable Wattage mod you must calculate the battery draw based on how many watts you are asking from it. (Actually the calculations work the same, but in a Variable Wattage mod you work both sides of the board separately, the common factor is the watts) Link to comment Share on other sites More sharing options...
Tam Posted January 22, 2016 Share Posted January 22, 2016 Okay, guys, enough with the geek. You still haven't answered his question: which battery would he be better off with if he should buy the RX200 (I think that's the mod he was considering). If he's not planning to go sub-ohm or micro-sub-ohm, what's the bigger bang for the buck and still give him some playing around room? Link to comment Share on other sites More sharing options...

Watt will I do with my lengthy geeky reply to Jason? Anything but eFest. Jason made some solid cell recommendation. I'd go with those. Seriously, LG HG2 is good compromise with both mAH capacity and power head room to account for voltage sag. Samsung 25r is my second choice.

If he's not planning to go sub-ohm or micro-sub-ohm, what's the bigger bang for the buck and still give him some playing around room? I guess you are correct. @iQuit is correct. Nothing from Efest. They make some fairly decent batteries, but you have to be very careful. They released a batch of 35A 3000mah batteries that were proven to be LG MJ1s, a good battery but a 10A battery. This has been proven by 3 independent testers, on who is a reseller of Efest batteries. Efest has not only denied it but attacked 2 unpaid testers, who are only looking out for us. This has turned into a moral issue for me... I also think for the mod the 25R would be the best battery for the money. It is slightly out of the continuous discharge range, but, it has been proven to be a very stable battery even if mistreated. Sony VTC4 would probably be the best, but, unless you go to the vendors I mentioned earlier, or a very trustworthy, well known vendor, I wouldn't buy the Sony. A good $5.00 25R is much safer than a $9.00 counterfeit Sony. I also don't recommend the HE2 or HE4 if you are pushing the maximums. They are great batteries, just not, not nearly as stable when pushed like the 25R. 11 minutes ago, Tam said: Thank you. See? That wasn't so hard, was it. I can't type short replies....

Jsr1981 Posted January 22, 2016 Author Share Posted January 22, 2016 Very good responses! I buy all my batteries from liion wholesale. They are the only people I trust! Link to comment Share on other sites More sharing options...
Jsr1981 Posted January 22, 2016 Author Share Posted January 22, 2016 I see on liion's site that the Samsung 25r's are 100 amp pulse. What does that mean? Link to comment Share on other sites More sharing options...
Jsr1981 Posted January 22, 2016 Author Share Posted January 22, 2016 Why haven't y'all recommend vtc4's? They are 30 amp batteries right? Is there something wrong with them? I thought they were the best. I know they don't have the life as the others but that's not a big deal to me. If I get them from liion wholesale they will be authentic correct?

As Jason indicated above... Sony is the MOST cloned battery or re-wrapped battery on the market, and unless you are absolutely sure you are not receiving a re-wrapped Trustfire or something like that... (i.e. buying from trusted source), it is best to get the Samsung or LG batteries (also from a trusted source), mostly because they are less likely to be re-wrapped junk, and they are also considerably cheaper than the Sony. iQuit and Tam 2 Link to comment Share on other sites More sharing options...

VTC4s are great! It does have lower capacity compared to 25R and LG HG2, and twice the price point (sometimes more) of 25R. Others who are not pushing very high wattage find 25R, etc are good enough for their needs. If power requirements is more important than longer battery run and do not mind the price, authentic VTC4s all the way. Jsr1981 1 Link to comment Share on other sites More sharing options...

But Liion is a safe place to buy them. If you have a problem they will take care of you. 7 hours ago, iQuit said: VTC4s are great!

I personally will buy 25R's, LG2's or 30Q's until something better comes along. I also have a set of HB6's if I need to pull more amps. (I also have a few sets of VTC4's) I have no need to pay the premium for the Sony's. There is certainly nothing wrong with them though.
