first mech mod and back story

[twitch99xl]

new to the whole scene, thankfully the forum and the employees at the local vape shop i frequent are amazing and don't mind helping a noob understand some things, now that that's out of the way.

Attended a cloud comp at uvape in Davie fl. They had a little raffle going on for random prizes, figured maybe ill get some free juice, nope winning ticket pulled for the Tugboat v2.5 with a twisted messes v2 rda. love this thing and just wanted to post up and give a shout out to uvape for the freebies from the night. now my question here is battery recommendations seems everyone has there favorite but is there a list breakdown by user generated specs and not mfr crap.

@Mooch is the battery guru. He posts most of his stuff on ECF, though I think. You can find him on Facebook here.

perfect thank you

If you're going to push the amps with low resistance builds, LG HB series is your best bet for safety. Sony VTC4s are good too but you want to stay strict to that 30amp limit. Samsung 25rs are my favorite if I'm not pushing the amp rating, they are 20amp rated but the safest battery out there. Those are all I'd use on any mechs. I have heard good things about LG HE series batteries but they aren't as safe to push as 25rs but apparently pump a bit more power when fresh than 25rs from what I've heard.

I use liionwholesale exclusively but seen many promote illumn as well, best to stick to trusted suppliers as there are fakes out there, especially a big problem with the VTC line and I heard the LG HGs are starting to be a problem as well.

I've currently got eight of the Samsung 25r cells. I have a pair for my Noisy Cricket, a pair for my X Cube II, a set for my RX200 and a single one for a couple of single cell mods. I have had no issues using them. I don't go below .5 ohms on my Noisy Cricket, though. That's plenty rowdy enough for me, and still leaves a little headroom for safety.

Forgot to add "The Chart" Though it's an older one if you find the up to date one you'll have some more findings on the offbrand stuff though the batteries from the big 3 should remain the same (LG/SONY/Samsung). One thing the HB2 seems to be the highest limit though I read the HB6 runs cooler at it's CDR which you should still follow and running cooler basically means it's safer, so while you won't be able to push it as far it will be safer while you're not being too dumb

Sitting on 8 as well and ordered another 3 (as well as some 30qs) for the RX200 coming. Right now 2 sets of 2 for each of my mods, then I got a set of VTC4s and HB2s for my unregulated tubes. I'm going to be swimming in batteries!

Yea I've got a set of 25rs I'm using currently for the mech mod, they get a little warm but not hot. Currently running dual fused claptons around 0.08 ohms reading off my kbox200

That's pushing it. 4.2v/.08Ω=52.5amps

Rule of thumb on parallel is only take half the amps of the second battery, though overly cautious it's not a bad rule.

So with 20amp cells that'd say 30amp limit. Now realistically you can push 25rs to 25amps without worrying, 30 doable though that's really Danger zone. What you're asking from them is at best 26.25amps each that's assuming there's no loss in the parallel system (there is and that's why the 50% "rule").

Anyways, not trying to berate you but I'd build something at the .12-.15Ω range at the very least for now, and if you like the build you're working with grab some LG HB series batteries as you'll still be on the higher end of safe even with the 30amp cells due to the power loss in the system and all that jazz. I assume you're using 22g cored FCs? Try 24g cores that should be right in that .12Ω area.

Right now you're pumping 170w-ish, with the jump to .12Ω you'd be at 114w-ish, not the same heat but a MUCH safer setup.

EDIT: That's why I like 25rs so much though, you're pushing them HARD and they're still chugging along. Not the best idea, but damn those batteries are resilient.

well before i blow my face off let me scare you and myself even more that build is in this, im going to shelf this and do some serious reading before i get on the mech again. im going to have a friend build me a dual setup 26g inner 32g outer 8 wraps around 3mm should put me around .3ohms puts me at 14amps, till then ill stick with the tfv4

Eek yeah, thought it was a parallel. So yeah, 30amp is .14Ω limit. Dual 26g Kanthal cored Fused claptons are good, 6-7 wraps and you're at about .2Ω which is well within safety.

get that done tonight hopefully, bookmarked some reading material and calculators to read over, probably order some batteries next week as well
