I am rebuilding a first gen 128v 6.5ah hybrid battery used in bmw activehybrid and mercedes s400. It uses Saft VL6 cells. Is there anything comparable that i can buy that matches the discharge rate (100amps & 300amp burst) of this cell? Was thinking to go with a bundle of 2170 cells in parallel4yr ⋅ limitless2018 ⋅ r/ElectricalEngineering
SW Ethiopia Biftu roasted on GC. I used the 3 stage profile and a higher temp of 473*F since I figured a washed Ethiopia needs more temp than the usual...5yr ⋅ limitless2018 ⋅ r/roasting
No one ever talks about insulating boilers — yet seems to make a huge difference in temperature stability/recovery. Today I insulated my gaggia classic. First impressions: it keeps temp steady like a rock. Kind of amazing. I’ll do taste test tomorrow AM. (Orange hi temp silicone)5yr ⋅ limitless2018 ⋅ r/espresso
Bought some cheap ($10) but surprisingly sensitive mics to connect to phone to use as a megaphone to hear first cracks...5yr ⋅ limitless2018 ⋅ r/roasting
How on earth? The top one only had 2 months use maximum in Puerto Rico. The older one on the bottom had over 4 months of use in Miami, FL. Even dust isn’t that dark... could it be mold or just bad polluted air?4yr ⋅ limitless2018 ⋅ r/CPAP
Drilled a new 5mm hole for a digital temperature sensor in my Silvia grouphead’s stand offs for more accurate Group PID temp readings. I was under estimating temps by 8*F+ degrees in comparison & noticed how fast (in few secs) group temp can fall by over 10*F by putting in a barely warm portafilter5yr ⋅ limitless2018 ⋅ r/espresso
Now to figure out if the Sette I got yesterday improves taste or not over vario. What do you guys think?5yr ⋅ limitless2018 ⋅ r/espresso
My 2nd try with 120g on my Gene Cafe — the Altiplano Blend from SW. Ran it 17minutes total. 440*F for 12m then dropped temp to 420 for 5m, then cool down with a Dyson. Since I can’t really hear first or 2nd crack whatsoever (guessing) I’m sort of clueless...5yr ⋅ limitless2018 ⋅ r/roasting
2008 M5 — Is it normal for this valve supposed to be covered in oil? The entire hose cover appears soaked in it and the oil seems fresh. Is this the result of overfilling engine oil? (I have since changed oil)4yr ⋅ limitless2018 ⋅ r/BmwTech
Would a hole in the AC condenser this big still mean there’s still a lot of oil and Freon gas inside?4yr ⋅ limitless2018 ⋅ r/BmwTech
Is this considered too dark for SM Rwanda Kivu Kageyo? The 2 espresso shots with varying shot lengths so far are kind of flat with not much complexity but tasted bitter both times, almost like it was an oily Starbucks roast. Did I “bake” them?5yr ⋅ limitless2018 ⋅ r/roasting
Anyone have experience extracting this bean or the Maragogipe bean type? Can’t seem to get it to taste right. It’s had plenty rest time. Should I try grinding very fine and try pulling a shot at high temp and then low time?5yr ⋅ limitless2018 ⋅ r/espresso
Just received my HG-1 :/ Should I buy a new funnel with the little “windshield wiper” attachment? Or just sand it down and paint it myself...5yr ⋅ limitless2018 ⋅ r/espresso

Does your Sette get this much retention in its burr holder at “normal espresso” grind setting? (It’s literally packed but not “jammed”) Even my Vario has much less retention than this!5yr ⋅ limitless2018 ⋅ r/espresso
Installed a PWM “dimmer” ... seeing very consistent pucks/pulls as long as I don’t do it for too long. Only thing I don’t like is that the knob only gives me a very limited range. For example: 0-90% of it is “off”, other 10% is low-high. I think some have made full knob to work?5yr ⋅ limitless2018 ⋅ r/espresso
