I know someone selling a WP2, not sure if it is a v1 or v2. Is it worth picking up? I want to pick up a cheap 18650 torch to see what the fuss is about!
I have the Xtar WP2 II. It is a good charger that I bought based on many recommendations here and and CPF. I trust it much more than the cheapo 2 bay dumb chargers so prevalent on budget light sites. Batteries consistently come off the charger between 4.15 to 4.2v. Not sure if the regular WP2 is as good.
Absolutely, great charger. There have been some problems with the V2, some of them have been overcharging, others terminated the charge early. I think most that have reported a problem have had there chargers changed, I know I did and know it works perfect.
Just make sure you measure your batteries before use (full charge: 4.15-4.20V), especially if you use 2 bats in series. But that goes for every charger out there...
LOL. How often do any of you need to reset a battery? (a friend with a TK-35 occasionally come to unlock one overlydischarged battery, never happened to me personally.)
The last Li/ion charger I bought is a WP2 II. I'm not sure I trust the charger. On one side the battery comes off the charger at 4.17-4.18 and the other side the battery comes off at 4.23-4.25. I've only charged with it 3 times but it was the same each time. I have a cheap $4.99 charger from China that I use the most. It stops both cells at 4.18 every time. I'm wondering if I need to send the Xstar back.
It's happened to me 4 times in the last 6 months. Three times when I was doing a battery burn time test in a two cell light and once while using a single cell light.
Hm, strange :| After my C7 has shut down, I've checked the cell with my DMM and it showed 0 :| So I've put it in the charger for about 5 sec. Then I rechecked it and the cell had ~3V. I put it again et voila :) Normally it (charger) turns off @ 4.15V. (@4.18-19 would be awesome :P )
You are lucky I guess. I left my tripped cells in the charger for at least 5 minutes to see if if would eventually reset the protection, no luck. And that's with both of mine. (Version 1)
I have the Xtar WP2 mark 2 and it performs very well. Terminates charging at 4.16-4.18V. Independent channels with a choice of 500ma or 1000ma charging.
