datboi Posted April 20, 2022 Posted April 20, 2022 i just got myself a imax b6 v2. the charger can measure the internal resistance of the cells. however the reading is very different than manually measuring it. i took a few measurements with the b6 v2 (they're always a bit different with the same battery) then, i measured the internal resistance manually using a 1ohm resistor and ohm's law and kirchhoff law. what's your experience guys? can the b6 v2 mesure internal resistance of cells accuratly?

[*SNIP*] I would be willing to bet that 95% of Airsofters wouldn't know what Internal Resistance is, let alone verify the accuracy on a specific charger model. The B6 V2 is not a model that comes up often in conversations on here, unlike the numerous cheap B6 (v1) clones/knockoffs that proliferate through Amazon and eBay that Airsofters seem to gravitate to. I mean, there are people that would gladly drop huge cash on stuff like a Maxx hop units/gucci red dots/scopes/stocks etc, yet balk at the idea of spending more than £25 for a decent charger. I see you've also asked this question across several other forums (RC and Rocketery), I would expect that they would be better placed to comment on it. Rogerborg 1

datboi Posted April 21, 2022 Author Posted April 21, 2022 manually i'm mesuring 200ohms. on the charger 110-125ohms. the thing that's bugging me - these batteries were around 50 ohm's a year ago. they're panasonic 18650b i've never used them since and they've been stored at 3.8v. how did they get ruined so fast?
