    Scubagen Mods

    I ordered most of the add on parts from PKZap27's build - I have several to build as well. Costs about $40 but you end up with 100 washers (3 sizes), 100 O'rings (2 sizes), 100 spacers (2 sizes) and 25 nuts.... I'm planning on breaking them into sets and will to put a few up on the clasifieds...

    While Waiting for my EQ- VV Bottom Feeder alternatives

    Quick look - http://www.dimensionengineering.com/datasheets/DE-SWADJ3.doc The efficiency graph starts at 8V for a 6V output. They are not telling you something- or more likely they are telling you that it doesn't drive 6V with less than 8V input.... I don't see info in the spec to tell if...

    no- no- no -no Now you did it Shadow :-) You broght the kids to a candy store and snuck out the back door.... I wrote a nice response - took me an hr to do it and when I clicked "Go Advanced" to check it, I got a log in screen and blew it away... Sorry....the short response will have to...

    When you swap your springs for the new one that comes with the provari batteries, do yourself a favor and clean it out real well.....

    While Waiting for my EQ- VV Bottom Feeder alternatives

    It doesn't need to boost, but it needs headroom - 1.1 or 1.2V at least- to run. Either that, or there is something wrong with it. What does it do with an 18650 when you set it at 4V?

    tenergy LiFePO4's with an Ikenvape 3.5 510 or IKV 3.5 cannon... PowerFeed is a must! and ALWAYS keep spare batteries around.

    While Waiting for my EQ- VV Bottom Feeder alternatives

    yeah - couple of things - educated guess- you're loosing alot of efficiency in that circuit - I don't know the details, but I suspect it's not set up to boost. Also... - when you stack batteries you do not increase the mAh rating- so you're effictively running a 7.4V (nominal) battery with...

    ProVari Variable Voltage Mod

    I use 3.5's and 4.2's ;-) with the IMRs I couldn't run below 1.9/1.8 without errors. Even at 3.3V. I definitely get better mileage with standard attys. I can't remember the exact number but I think it was around 20% worse at 6V at the same power level than 5V....

    New Batteries coming soon - ProVari Power 2500

    As Ukeman said, check the voltage when it starts flashing... That was happening to me about 2 weeks ago - I swapped out springs, cleaned the batteries and connectors (see details a few pages back) and now all is good. If your unit is brand new contact provape- something is wrong. Otherwise...

    New Batteries coming soon - ProVari Power 2500

    Could be a flakey battery- could be crud/juice/oxidation on the battery's ends (you might want to clean them with some achohol or polish)-

    ProVari Variable Voltage Mod

    In general I agree with you- the premise would be that the HR atty was made by using more wire as opposed to a thinner gauge. Also, temperature of the wire is a function of current and wire gage- on paper, the longer resistance wire would run cooler because it would be passing less current...

    ProVari Variable Voltage Mod

    Have you put it on a scope? I don't believe they are doing PWM to regulate the RMS voltage. Buck/Boost regulators do in fact generate pulses and most can be tuned or programmed a bit, but I do not believe they are using full blown PWM and adjusting the duty cycle to give you the full range RMS...

    You said you were done- apparently you weren't.... From Uwe: What more update do you need- there were 800+ orders- the Co-Op was open on the german forum way before here. Do you think you were one of the first 150? It was pretty clear that this was going to take a few months (2-3...
