The 21700 won’t fit in my Lii-260. They do fit in my Lii-100, but I’d like check the capacity and resistance of new batteries.
Is there a 21700 battery holder around, so I could use my programmable charger?
Or, what’s the cheapest charger that will fit a 21700 and give capacity and resistance?
I was thinking about the Xtar VC2S, but one review said the 21700 won’t fit.
Sure would be nice if there was a 21700 forum to have all the related discussion in 1 spot. Strange thing to observe, there’s 2 “AA” forums, there’s 2 “AAA” forums, there’s zero 21700 forums. Seems a bit odd to me. Actually…seems more than a bit odd to me.
Haven't seen a 21700 battery holder with terminals, but . . . (just saw the link above)
The 21700 fits three of my chargers (1) Xtar Dragon VP4 plus (2) SkyRC MC3000 (3) AccuPower IQ338XL
The two 21700's I own are the Samsung 40T and 48G. These two in particular may require spacers for the + terminal, because the + terminal sits just below the top of the battery housing, which may not mate properly with the chargers terminals. I just use a bent paper clip.
All three above do capacity tests, as well as resistance. The Xtar in particular comes with a set of dedicated probes for measuring internal resistance.
Nice find, but at $19.67 shipping I’d be better off stripping down a Lii-100. I’ve got a cheap looking Warsun single cell charger that I don’t use, the 21700 fits, so I may do that.
Back to the chargers, I thing I’ll try the Xtar VC2S. I did think about the Xtar VC4, but don’t think these measure the battery resistance.
I just ordered a Miboxer C4 Upgrade in order to charge the 21700 in my new Sofirn C8F. The other choice for me from Miboxer was the C2-4000, but I opted for the C4 Upgrade. Hoping that it will work well.
