Should I just buy a Fullymax & rewire it? or is there a better choice?
DNA200????
I'm trying, very hard, to get the DNA75 working as I think/feel it should. I want the convenience of being able to swap batteries with the features of Evolv TC. It is proving to be a little(?) more difficult than the plug and play I anticipated. If you're happy with onboard charging rather than replacing batteries, go for it.
I have, & know it's the burst of preheat that sets off the weak battery warning
I'm a little OCD when it comes to that kind of thing & would rather replace the cells with some thing that would eliminate the warning The 200's have made me a custom to a whole higher level of performance thats why I only ordered 2 75's I was sceptical right from the start, that a single 18650 would do the job
Yes a Fullymax 900 3S, couldn't I just rewire it in parallel instead of series ?
I noticed Mike didn't do it that way So I'm assuming there's a better way?
I know he's real busy lately but hoping he will chime in sooner or later
The 900 would be a total of 2700mah, not that much greater than a good 2000-2500, but would have the discharge advantages of LiPO over IMR. Still, you lose the ability to replace a battery when needed.
Another dodge is to lower the cutoff voltage or shut off the "weak battery" message. Next would be dual 18650s but you pay a size and weight penalty. Cutting that preheat down would also solve it.

I'm well aware of every thing you just posted
I'm coming from 100 watt preheat, settling for 55 & still not getting what I need I'm all most certain there is a lipo solution to my problem. I know I would have to give up the replaceability But Whata you gona do?I'm not willing to let go the silo enclosures & the evolv 510's

That's the key, I'm going to solder three .950 together for a 75 build. I won't have to mess with soldering the tabs because these are wired. Turnigy nano-tech 950mah 1S 25~50C Lipo Pack (Fits Walkera V120, X100) (US Warehouse)
I know I may not be farther ahead from using 18650's but I want to give it a try, I can always switch back.
For 18650's I left the cutoff at the default 2.75 in escribe and I haven't had any issues. But my settings are lower, about half of Steamer's. For giggles I ran a watt hour test in escribe for a 3500mah mxjo battery, I ran it at 20w pulling 17.7 amps. It held well until the end when it got below 2.8 V then the battery started to get hot and I stopped the test, came out to 8.6 watt hours before it started heating up. What surprised me is the battery is rated at 35 amp, that's when I started searching and found the thread on the battery tests posted by Mooch, and he found the mxjo are way over rated. He found they work fine at about 20 amp but can't get anywhere near 35. Again here's the link List of Battery Tests | E-Cigarette Forum
BTW, if your going to test 18650 through escribe, start low and don't leave it unattended! I'm surprised evolv leaves that function in escribe when an 18650 is choose or at least give a popup warning.

Willie, I wouldn't leave a LiPO or IMR alone for a test cycle, just common sense not to. I'm having other problems with the 75s but am doing everything I can think of to rectify it. I will admit that I am leaning toward the idea that the 75 isn't for me, the firmware is too different from the 200 in many respects and, is suspect, causing the problem I am encountering.
Yeah, I'm with you, I doubt the 75 will never become my main mod. But it vapes a little better then a 40 and in a smaller beater mod it would be good while working in the shop or outside where a pocket sized mod is convenient and it's going to be knocked around. I'll keep my nice 200's for everything else.
ETA I'm sure most here wouldn't leave the mod while testing but I worry there could be someone new to these that might and cause a problem, and with lawyers just looking to sue. If I was evolv I would at least have a popup warning.
On another note, prayers for the baton rouge police officers. Sad to see the state of our world today, wish I could go back in time to when I was a kid when the world was sane.
Try changing it to 2.8 just for S & G & see if it performs w/o a weak battery error through a longer range. As Awsum said, it is only while triggering the sag is present so fool it into not cutting off prematurelyI left it at 3.3
I know it's the preheat that killing me
I know what I'm up against & also know I need lipo's in there, to get the performance I'm looking for, hence my question

With mine at 2.75 I set the screen the show battery pack (voltage) so I can keep an eye on it and know when it's time to swap out the battery.
I was going to suggest the same thing. 3.3 seems high. I thought it started or defaulted to 3.09? I could be wrong tho, maybe that's the lipo setting.
Did you ever say which batteries you are using?
Gee I didn't even know that the preheat could be set longer than 2 seconds. I just got done giving it a try at 3.3 seconds.
Problem is for me is my pulls aren't even 3 seconds....LOL
My pulls amount to maybe 2 sec unless blowing clouds.

I was going to say the same thing. My draws are usually 3 to 4 seconds at Max. When I use pre-heat, it's 1 second and usually 40w soft or medium.
Does TC still apply for preheat? 55w at 3 secs seems like it would burn (scorch) cotton?
I will try lowering down to 2.75 & see what happens
I use VTC5's 20 amp 2500 mAH I tried a VTC4 it has a bit higher Amp rating but lower mAH no significant difference

I had similar results, in terms of the problem I'm experiencing and in terms of battery life trying LG HG2s and LG HD2s. Both types are brand new and authentic to the best of my knowledge.
Nice to know someone else is having problems with the 75, misery likes company
Just noticed this on the evolv forum View Single Post - Early Firmware - Evolv DNA Forum

Just the firmware file for now -- you can update to it using Tools->Update Firmware.
It's a small change: some batteries can't push 75W, and more can't when they get to a low state of charge. Even when your power levels are 20W or so, for temperature protected coils you get a 75W preheat. So, we've reduced the aggressiveness of the Weak Battery warning to reflect the reality of the puff, not the preheat.
Weak Battery now takes about a second to appear. It also does the less-annoying thing of flashing the battery icon, instead of flashing a message obscuring the screen.

I would assume, and we all know what that can do, that little tweak is in the latest version of standard firmware by now.
Soft cell cut off is @ 2.75 volts now & it's helping Same settings 45 watts 450 degrees 55 watt 3 second preheat Down to 41% battery life no weak battery warning yet Sweet going to see how low it can go on the battery % before I get the warning again If I can get down to 20 or 25 % with out the warning I will be happy with that
Asking for help here in our thread all ways pays off
