no thats the new LCD tops will go into production real soon, last round of testing.

Is it click on click off? Or just red when it's on?

 

[Bob Loblaw]

Those the new carts?

that's a hammer cart w/ the top still on

 

[THC SCIENTIFIC]

Is it click on click off? Or just red when it's on?

5 clicks on, 5 clicks off, since the engineer shipped out then went on vacation i wont know until i get it next week.

drool, drool, drool . this is what i am most excited for next to the new hammer carts.

looks great! dare i ask the dreaded and inevitable, "how long ?"
looks like it has single and dual cart option unless my eyes deceive. two different tops?
want!

Ya two different tops, 5 different colors. So many to produce haha. We are hoping to go into production in 3 weeks.

Sweet, that will be useful to watch your amps on the double top!

I think that kind of toggle switching has it's place (like for the hammer, or the revo/evo) where you want to turn it on for a long time and not worry about keeping the button pressed. But for regular cart use I think a momentary switch would be much more practical, especially with the higher power carts...

That'll be the final nail in my provaris coffin. Gotta birthday in July. Please be ready.

eh dont forget the other one and we already have the nails ready in the nail gun, can we pack other models in as well? You choose.

i believe he means on/off like omi1 and o-phos not on/off like hammer

 

[THC SCIENTIFIC]

we thought about having a 5 click on/off button on the persei, but this is done for safety reason. The button is flush with its housing, and since it is small for some, pressing it 5 times would be difficult, also the button wont turn on in your pocket unless you have keys with it and other junk.

got a persei today ...but went up to the vape lounge...filled my cartridge vaped a little while...had to go but i forgot my battery/cartridge compatibility (which batteries for what carts chart)haha damn thing works like a charm ...so anyone got a pic of it? is it safe to get dual 3 ohm carts going at 7.4? and to get it running at 6v i would have to buy a separate battery? (not included in the kit)

The included chart says 'no'. Not only that, it says the same thing for 4 Ohm carts (red for 6.3 to 7.4 Volts) so it's not just a little bit overdirven....

3.0 Ohms shows 'ideal' for both 4.3 -5.2 and 5.3-6.2 Volts, 4.0 Ohms shows 'slower' and 'ideal' respectively. 3.0 shows as 'slower' (but still green) for 3.7-4.2 Volts.

The only green option for 7.4 Volts on the chart is the 5.0 Ohm carts.

The Persei currently has not amp limit we building it into the next phase and replacement parts.

The button is the issue guys, it is rated at 5amps. That's where my 5 amp limit comes from.
I'm sure it can handle very short bursts but it's not going to stay working for ever either.

OK, I took a break last night from the rigors of 8 testing to get another look at this. As I threatened to do above:

Swell. I went to bed last night frustrated because I couldn't make sense of the numbers, and now this which is making even less sense to my fuzzy head.....

At one point I did some under load readings of V1, V2 and the TV Ultra supplies with 2.4 and 1.5 loads. I can see it's time to expand that with Evolution level loads and Persei....but the new Persei will no doubt change that???

Some time back, when the 'magic adapters' dried up I had to strip my test rig from the earlier tests. Now that they are available again, I built an improved version (allows for real time current measurement) and I found out that Persei seems to have significant internal resistance in play. About .22 Ohms it seems. Some no doubt from the battery itself, some from contact and other similar resistances, some from wiring and no doubt a lot of it from the protection circuit. In total it's significant to us. Unloaded (no carts) my Persei was putting out 4.02 Volts when the button was pressed. A 2.4 Ohm cart (which actually turns out to be closer to 2.7 Ohms when accurately read on my rig (Voltage across and current through the device measure at the same time) drops this to 3.73 Volts when the load is pulling 1.31 Amps. Only 3.55 Volts of that actually makes it to the load, the other .18 Volts being lost in the current meter but being included in 'what the Persei sees'. Changing to my LV Evolution we get only 2.74 of the total 3.27 Volts the Persei puts out supplying the 3.66 Amps needed. A far cry short of the 5 Amp limit on the switch.

This may change with the next model (and should no doubt be much improved with the VV unit which should compensate for such losses and put out the specified voltage no matter), but for the current version I can see no safety issue using the Persei to drive the Evolution (which in this case calculates to .75 Ohms). The other side of this is 3.66 Amps times 3.27 Volts means it's only going to get 12 Watts, not the 20 we wanted (since we don't supply full voltage). It seems safe and it does work...just not very well compared to the TV supply with it's lower losses.

More poking is called for, but as of now I see no overload issue using the Persei with Evolutions in LV (SV should of course be even lower current). We've got over an Amp of margin still. This should also cover the worst case cart load (two 1.5 Ohm in parallel) which turns out to be the same load as Evolution?

I can verify:

With a battery at 4.21v my evo only got 4 amps. But I still use the Persei over the T1 unit because the aw imr 18650 2000mah is a ridiculous () power source, and the T1 switch makes my thumbs hurt. I'm tempted to buy a Hammer just for the click on/click off top...

Thanks for the 0.75 ohm reading!

Thanks for the confirmation. You too see no over current safety issues, right? I agree, my thumb gets tried holding the slide up, which is why I went to Persei for this, but the heat is definitely lower there (takes longer to come up) but now I understand why.

I've never tried IMR 2000 mAh cells, but the IMR 1600s I'm using should have the same (or even slightly better) performance for 80% of the run time. One thing sure, the combination of them and the Persei does not compare well with the TV Ultra supply with it's protected 17670. Mine delivers a full four Amps at 3.60 Volts under the same conditions. That's 14.5 Watts against a bit under 12. That extra 20% makes a big difference it seems.

But things change quickly. I wonder if lower loss supplies from THC will make it to market before some easier to work switch from TV. Or one or the other brings out a new supply with bigger battery or better options. Or one or the other delivers a useful pass through and stands this all on it's head again?

We are indeed blessed by the progress going on on already useful gear.

Thanks for the confirmation, you're welcome for the resistance number. Now I think you can see the issue? The .75 Ohms in the cart gets the .22 Ohms internal resistance added to it, the 'ideal battery' in the Circuit Analysis model 'sees' a total of an Ohm, right? That sets four Amps. The four Amps times (the real) .75 Ohms means only 3.0 Volts develops in the load, the other 25% of the power is heating the battery and electronics as the load heats. You only get 12 Watts, not the 20 (actually a little over 18) you might otherwise expect. Or the 14.5 you'd get with the Ultra.

This actually folds back to PA issues with TV cores. It looks like 5.5 Volts might be a better target at the coil terminals for SV Evolutions, the 6.0 Volt supply I'm messing with is hotter than fresh batteries under load it seems....which is why it'll take some more head scratching after I finish with the 8 testing and return the prototype, hopefully right after the holiday.

I'm surprised your 17670 is performing so well, mine is actually at the bottom of my heavy duty batteries.

This is just battery to load, no switch or persei top included. I am using an amp setting on a multimeter but the added resistance should be constant for all tests:

----------------------- 4.20v ---- 3.85v -----
===================================
AW 17670 1600mah ---- 3.9a ----------------
AW IMR 1600mah ------ 4.2a ------ 3.8a -----
AW IMR 2000mah ------ 4.1a ------ 3.7a -----

ok cool...thanks for the reply but i did a little looking around and at planetvape...where u can buy the single carts it has the chart. ...time for me to decide if i want the carts or the hammer....always a hard choice with delta9 coming out with great stuff

 

[VAPORIZER22]

So is the standard 6v Evo safe to run on the Persei with the single top? Or is is just the double top combo of an Evo and Omicron/Persei cart that is a no no?

Thanks

 

[JoeKickass]

just the double top combo of an Evo and Omicron/Persei cart

Yup just low voltage evo and an omi cart, but research is currently being done it might be possible...

Joe's got it. Just to be clear, the issue is not with the SV (6 Volt) version. There the current is a bit over 3 Amps worst case plenty far away from the 5 Amp limit. Remember, however, that you need to put the RCR123A batteries in since they are 3.0 Volts. Using IMR or other 3.7 Volt types will be too hot. You should also check your charger capabilities as some but not all will charge 3.0 and 3.7 Volt batteries.

There's probably even enough extra current capacity in the switch to drive an Omicron cart at the same time at the higher voltage, but for the life of me I can't see why?

Thanks dudes. I was planning on using the RCR123A's, Tenergy and AW, using the Tenergy charger.

As a follow up question, is the LV Evo and LV Rev safe to use on the single top as well? Not sure if the LV Evo by itself exceeds the 5 Amp limit.

Loving the 1.5 cart on the Persei.

Thanks again

 

[JoeKickass]

but for the life of me I can't see why?

Have to say it,

Why not?

lol, but I agree that with a high voltage cart it would be more than any human could stand. The only combo that I would even attempt would be a 2.4 ohm cart and the evo. The 2.4 ohm's are really the only ones that you can hold down for the whole time and the heater wouldn't run dry or burn out.

Being able to inhale and remain conscious the entire time is a completely different story...

As a follow up question, is the LV Evo and LV Rev safe to use on the single top as well? Not sure if the LV Evo by itself exceeds the 5 Amp limit.

Yup using one by itself is 100% safe, I've never seen the evo draw even 4.5 amps
