Battery Internal Resistance Measurements
I was curious about my very low imput voltage drop on my Raptor with the 4200mAh A Spec. Only .04v drop while mamu was getting .2 to.4 with the Lg 18650. So I tried several older 7.4 packs I had laying around. A couple of Zippys and other Lipoly all over 5000mAh 25 to 40C. On all I got between...- BJ43

By the thickness of each, they have 3 cells parallel per pack. Three 1866.66666 mAh cells:confused: Strange size. Why is each pack marked with 7.4v?- BJ43

Not drop in if those are each 7.4v.:) I have the 5000, 5600, and the 6000, all 3.7v and have the same size hard shell. 3 5/8" x 1 13/16" x 3/4". So a 1/4" longer for the 510 and 3/8" thicker for the DNA. Size feels good in the hand and easy for beginner modders. And me...:D- BJ43

Raptor Flip-Top VV Mod with 20A, 120W dc/dc converter...
Strange, mine did the same. I was monitoring output it flickered and flashed, then when I ck input it is at 5.51v. Are the other parameters of the 6.2v diode I want to use OK? I am no electronics wiz..;)- BJ43

Ok, third day on the 4200mAh lipo, waiting for the diode to stop me. Input showing 7v and 6.95v under load, 5v output, The screen was on output and all of a sudden it flashed and went off. When I switched to imput it showed 5.51v..:confused: So put it on my charger, cell 1 was 2.68v and cell 2...- BJ43

Just hemp
Don't know why there is such a big deal about getting it fluffy again. We use such small amounts each time, it is easy just to fluff a little with your fingers. I personally just keep some in a small jar with VG and it is always fluffy wet.:) Those long stringy clumps I use to wrap tight around...- BJ43

Just hemp
To each his own. I completely disagree with this.:) IMO Swelling does not choke. Too tight chokes but every lab test I did (many) swelling never reduced wicking (capillary action). I pack pretty tight and chain vape at over 15 watts and have never had dry hits. Remember the same with SS wick and...- BJ43

Raptor Flip-Top VV Mod with 20A, 120W dc/dc converter...
I have been concentrating on vertical coils in Russian type RBAs with all the air being drawn thru the coil and hemp fiber around the coil. I am using mostly R41 wire. The lower the ohms the smaller the vapor producing area on the coil. So my 1.3 ohm at 17/18watts 5v is great, if I go higher to...- BJ43

My Raptor with 4200 mAh 65C lipo. 1.3 ohm, 17.6 w 5.1v. Look at the imput drop only .04. On all my mods with 18650 my imput drop has always been in the .2 to .4 range, i have never seen .04.:) clic pic for video- BJ43

Raptor Flip-Top VV Mod with 20A, 120W dc/dc converter...
Mamu, I am really enjoying my Raptor and am ordering another one...:) I have a question, I would like to go a little higher on the output voltage. To get up to 7v, would I need to go to 11.1v lipo a different resistor and an 8.6v diode to cutoff at 9v?- BJ43
