<buZz> somewhere i'm amazed this works ; https://imgur.com/a/PHdTvVt
<buZz> the charger does seem a -bit- confused by the cell :P
<buZz> keeps charging to just 4.2V and then switch off, which makes voltage drop to 3.9V , and it turns charger back on, lol
<buZz> but, its charging, voltage -is- increasing over time somewhat :D
<buZz> 3400mAh cell, so will take forever at this rate i guess, maybe i'll just charge it externally
norayr has joined #maemo-leste
<buZz> also. suprisingly ergonomic? feels pretty nice in hand
Twig has quit [Remote host closed the connection]
<Wizzup> buZz: this is for charging?
<buZz> no, its being used as battery :P
<freemangordon> buZz: 300mV voltage drop?
<freemangordon> doe not sound good :)
<buZz> could be :) the wires are verrrry flimsy
<freemangordon> maybe you should replace them with thicker/shorter ones
<buZz> i'm amazed it works at all really :P made a extra leste SD card, gonna see where battery calibration puts it with these wires
<freemangordon> those sound like 3-5 Ohms
<buZz> yeah too high
<buZz> two parallel might help
<freemangordon> or one thicker?
<buZz> as far as 18650 cells go, this is the biggest capacity available now, afaik
<freemangordon> those look like consisting of insulation and hair-thin wire :)
<buZz> oh, the wires on the cellholder? its whatever aliexpress vendor put on it
<buZz> you assume two parallel wires
<buZz> i ment two parallel cells ;)
<freemangordon> ah :)
<buZz> to lower internal resistance
<freemangordon> Wizzup: are you going to test sip now?
<Wizzup> freemangordon: in ~20 mins or so probably
<Wizzup> I have a lot of dishes to go through ;)
<freemangordon> heh
<bencoh> buZz: are those Li-Ion?
<freemangordon> Wizzup: you should buy a dishwasher ASAP
<freemangordon> bencoh: 18650?
<bencoh> well, if that's what it is, then I guess it's Li-Ion yeah :)
<freemangordon> mhm
<buZz> bencoh: yes
<buZz> specifically a inr18650-35E
<freemangordon> though, I think 3400 mAh is a bit of...ummm...
<freemangordon> a wishful thinking :)
<bencoh> haha
<buZz> i dno, its really legit samsung though
<freemangordon> oh, sammy ?!?
<buZz> yes
<buZz> Samsung INR18650-35E 3450mAh - 8A
<freemangordon> then I don;t know
<freemangordon> looks legit, yeah
<buZz> up to 8A discharge
<bencoh> could easily fact-check it based on battery volume and reulting (announced) energy density
<freemangordon> buZz: see reviews re impedance
<bencoh> " max discharge current: 8A" that's sick
<freemangordon> I doubt 2 in parallel will make any difference
<buZz> 22-24-28mohm
<freemangordon> "Impedance 22-24-28mohm"
<freemangordon> mhm
<buZz> -milli- ohm?
<freemangordon> sounds about right
<freemangordon> oh
<freemangordon> yes, sounds about right
<freemangordon> d4 battery has about 150 mOhm
<freemangordon> so, I would bet on the wires ;)
<Wizzup> freemangordon: :D
<freemangordon> bencoh: yeah, sounds crazy
<buZz> these cells are often in vapes and drill batteries etc
<freemangordon> there seem to be ones with 35A discharge current ?!?
<freemangordon> *that* is sick
<buZz> freemangordon: lipo is even sicker :P
<buZz> i have 5A lipo cells with 20-40C discharge rate
<buZz> 5Ah*
<freemangordon> omg
<bencoh> uh
<bencoh> sounds like the best candidate for a homemade UPS
sunshavi has joined #maemo-leste
<buZz> maybe
<bencoh> just stack a bunch of those
<buZz> there's even higher, check LTO batteries :D
<bencoh> Specific energy60–110 Wh/kg[1]
<buZz> 10C at 40Ah , it can discharge at 400A
<bencoh> Energy density177 Wh/L[1]
<bencoh> sounds good enough for me tbh
<buZz> and charge at 8C , 320A :D
<bencoh> huhu
