It is the same charger. The one with temperature is much never. Soshine sent a couple of chargers to me recently (Not all reviews has been published yet) and the one with temperature is from that couple.
I do very seldom go back and improve old reviews, when I improve my testing it is usual only used on later reviews.
I do have equipment to do a lot of different tests, but I try to select the most interesting/revealing test and I do always look for good ideas to improve my testing.
Not 90C, more like 50C. Generally I like Xtar, but the original XP4 do get rather warm.
Maybe, but they will be with the specifications (Usual 300 or 500 cycles). I.e. I would not charge with less than 1A, except if I have a lot of time for it.
And even then I always uses 1A for 18650, except if I really need the battery fast, then I increase to 2A.
Oh my bad sorry, i got things mixed up, i read like 5-6 of your reviews, so you get the idea :8)
Anyway, it goes to 50c on batteries, and it has a bug, does the new version solves this, and how can i tell its the new one (where can i buy it) thanks!
Hmm what about the LUC V4 2014? the batteries doesent get hot ~ 40c, i would like to know does this charger has option to change charging Amps, from 1 to 0.5? and also where can i buy one i found it on ebay, but its to expensive, like 50 euros. Any USA shops have it on sale with free shipping?
The LUC V4 is only $29.99 at Mountain Electronics (out of stock at the moment), plus shipping but I expect still much less than that ebay price. I have one and didn't feel any heat but I place chargers on top of a computer where the top fans keep the air moving.
You also might consider the MCC4 from Thrunite. It charges 4 cells at 1A also. It is slightly more pricey than you wanted in your op but Illumination Supply has them $39.99. I love mine!
