That explains a lot :D TY!

Not according to Tenergy. They claim a 38 amp peek. And again, not hitting 19 amps but I'd feel safe at draining a fresh cell at 20 amps. https://power.tenergy.com/tenergy-propel-sub-c-3800mah-nimh-flat-top-rechargeable-batteries-special-size/ 10th scale offroad here. Fried a lot of cells...

How much space should be between the herb and the bulb again? I have a screen above the bulb but it seems to want a little more gap than an 1/8".

I am saying that these elements add resistance. Basically, if you push a box mod hard to the rails, it can see a 0.056 ohm resistance. If I add wire, that 0.056 ohms becomes something greater reducing the current requirement. In your take you are not adding the additional impedances from wire...

we're not pulling 24 amps. easy calc -12v@2a source power to AP v-any. that is more power than the cell provides. Argggh, I don't want to fry this new LB on a peaked cell without a load. This is a hard measurement to get. Basically what I've been getting at is that voltage is lost along the...

I concur with your findings. Your electric bill would go way up on the LB :D Teasing out that last bit of vape spirit from flower takes a lot of energy in the LB. That is the price of conduction with flower. And at that point in the session is when you need voltage. But a fresh peek charge...

To do the math justice, you need to know where on the discharge curve unacceptable voltage levels commence. The knee of the curve kind of blurs on Ni-Mh at anything over an amp. I asked Tenergy for that data and they wouldn't provide it. They are one of the few players left for the hobby and...

I hadn't measured the voltage at the rail contacts yet using these cells. These cells are very capable of pushing juice being from the RC world but usable capacity at these levels are seriously diminished. The 3800mah cell struggled to complete a trench to near-blackness. 4200mah cells are...

You need axial pressure and some radial pressure. That is why I was thinking a course fitting screw thread. Something very subtle but definitely grips the loop-contact and has an electrical spring contact in those threads. The diameter I settled on for reliable loop-contact was dia. .56".

Cyber Monday is for stocking up on herb!

True, but don't overlook contact resistance with stainless steel. That seems to be what killed the fuses. The center contact got very hot at the nickle/stainless steel interface. When I made that straight copper, no issues with heat whatsoever. I could only check the input current when I...

I did one test that you need the data from. I used the PA and measured the voltage at the rails. I got 1.15V being delivered to the stainless rails at full power which is way more than cells deliver. This measurement removes all other losses but accounts for the rails. The open voltage for...

I'll just strip all the insulation and add my own PTFE tubing. Easy enough. Yesterday I came up with a different joint. Imaging holding the metal while saturating at 10 watts :rockon: ...and as an aside, also provides the air path so I can seal these shitty sockets. Okay, quick build to...

Correct. The Dib trench is peanuts. 5 watts will get you serious clouds. I see well under 200 milli-ohm internal resistance consistently on current cells. I only have a few cells that come in at under 50 milli-ohm internal resistance. Those work nicely on the full sized trench but not long...

I see it as 'expensive' for the LB. But it can be as simple as a PA and a battery pack repackaged in a 3D printed case. The problem is the long cord. The losses are significant over a longer wire. Even my PA-v1.0 gets quite warm at the puck which is also way too heavy. Now you understand...

I think a connection between box mods and the LB would do well on eBay. MF is still pretty popular for the curious like myself. I can tell you, I still love the nuances available with the LB. Power options has been my only peeve until now. If nothing else, one could marry an 18650 or 14500...

I'd suggest MF's power adapter with a remote 12V battery pack. very pocket-able. That is what I was doing before making the brute cells. @scy123 - Now were talking :tup: Yes, the dual button push stopped me from making mod adapters. I did run my poor man's Muad Dib with the box mod I have...

A lot of current box mods will go down to 0.05 ohms. Finding ones with appropriate firmware may be worthwhile. Actually I've learned that the LB challenges the internal resistance of cells. Sub-C high drain; no issues - AA high drain; issues! Glyph cells was a thing of their time. Now...

back up and add the http... that fixes it.

No toes to step on so no worries. Your video actually shows the Muad Dib modification. The LB resistance is right at 0.056 ohms. Yes, I got just over 0.2 ohms on the little trench screen. Again, original Ni-Cads work fine on these. Nice to know on box mod options. Last question, what makes...
