"Sweet spot" on RX200

[Johntodd]

Hi! Love my Wismec RX200! But what is the sweet spot on it for resistance? I am not using TC, I'm a regular kanthal-only dude.

I'm just not getting the battery life I thought. Still changing batts every day, even with 3
18650 Samsung INR18650-25R R5 2500mAh (GREEN) batts.

Thanks!

Triple twisted 24g 9 wraps dual coil.
. 16 ohms, betwwen 100 and 130w.
Thats my opinion, using he4 25 amp bats.

I rotate 1 set every day. Take em out at 7a when i get home, put fresh in, put on charge, when i go to work at 10, put in the freshly recharged. Repeat every day. F9r me it's worth it. Cuboid can handle only a few hours on it. And cant fire it above 2 batteries limits, around 130w, RX goes all shift and day.

I wouldn't say there's a sweet spot because that's all preference. I'm not a heavy cloud chaser as the person above. I vape a dual 26g macro coil ohming out at .6 at 50-52 watts. I get AT LEAST 3 1/2 days battery life off a full charge on the 3000mah purple efests

If you want better battery life then build higher ohms with thinner wires or even go single coil.

 

[Johntodd]

I'm at 1 ohm with 28ga. dual right now. I thought that would give better battery life.

When I say "sweet spot", I mean the resistance where the mod is at it's best or most efficient.

I must say that I am getting a great vape. Just changing batts every day like I did with all my other mods that have 1 or 2 '650's in them.

I believe Daniel at djlsb may have an in depth review of the rx200 showing you its actual wattage output at different resistance levels.

If I am chain vaping at 75 watts with a .18 ohm build then I get about 5 hours on the LG H2 batteries. If I use a .3 ohm build at 50 watts then I will get all day . Again if I raised the ohms to .5 and lowered the wattage to 25 I maybe could go 2 full days. This is about the same that I get on a couple of my dual battery 200 watts mods, so no more battery life for me with 3 batteries with a low ohm build. Higher Ohms and lower wattage = equal more battery life

The resistance doesn't matter though, only the watts do. There's definitely something wrong with your rx200 if you get no more battery life than from a dual-battery mod.

No I am getting great battery life from 2 of my dual battery devices. Although the RX200 is a good device for the money. It is not a Great device or the best on the market, there are some better. resistance does matter to a certain point. A .15 ohm coil will not fire or will not fire properly at 45 watts

I'm not saying that the rx200 is great (though in my personal opinion it is), simply that there appears to be something wrong with your particular device if it has such a bad battery life.

The battery life is not bad for chain vaping a .15 ohm build at 75 watts

 

[KenD]

Nevermind

I've been using my RX200 for about 2 months now. 0.6 ohm dual coil build. Three LG 18650 HG2 3000mAh batteries. Rarely vape more than 30 watts, occasionally I "push it" up to 40 watts.

I'm only getting a day and a half to two days per charge, but I'm pretty much a chain vaper.

On my cleito tank at 0.2 ohms my rx200 lasts a long time for days and I think it's good vapor production but that's with 3 Sony vtc5 batteries in it.

Ohms Law Voltage divided by resistance = amperage

 

[KenD]

Ohms Law Voltage divided by resistance = amperage

Sure, on an unregulated device. On a vw power is "bought" or "sold" with amps. The watts are stable/set. If the resistance is low, less volts are required to reach the watts. If the resistance is high, more volts than the battery has are required and more are exchanged by increasing the amp draw. As the battery drains more amps are also needed to maintain the set watts.

Using simple ohms law calculations, please show me the amp draw of a .5 ohm coil at 40w at different battery charge levels (single-battery device, assuming 90% chip efficiency). Compare that to the amp draw of a 1 ohm coil at 60w.
