AW IMR's -- What am i doing wrong or missing the boat on here?

[DaveP]

I can only say I have 4 of those trustfire chargers and they all charge IMR or protected to 4.21 volts... This is tested on a fluke miltimeter. I also have three friends that have them and they all ckeched with different multimeters (all higher end like the fluke) and their readings were similar (within a couple hundredths of a volt)...

Sorry I cannot input further but, I don't think I'd immediately discount the trustfire, there's a lot of them in service and working fine.

I'd definitely keep an eye on them though, in the issue of batteries it ALWAYS pays to check and be safe.

I agree on the Trustfire TR-001. It's a good charger, but it does take about 3-4 hours to charge 18650 batts. I rotate 4 AW 18650 IMRs on my TR-001 and they all come off at 4.21v. I verify that on first vape with my Provari's built in under load voltage display. They show 4.21 under a 3 ohm load for a short time and then begin to drop. They stay at 3.7v - 3.8v for a long time and then gradually drop under load to lower voltages. When they get about 3.5v, I switch out and recharge.

I get the AW's from Provape for about $12 and trust that they are verified to be AW sourced.

Here's an in depth comparison of the xtar WP1 and WP2 chargers compared to the Pila DSD and DX.6105 chargers complete with many color graphs and comments on what you are looking at in the graphs.
