  • What device/application do you use this with? Used to test and charge several hundred D-cell NiMH batteries

Solid battery tester with the capacity needed to test four D-cells at once

Overall, I like the build quality and it seems to be a good tester unit (I own ten VP4+ units). One VP4+ (that I bought from Amazon) had an issue with the rubber zipper pulls on the case crumbling and breaking for some reason. I have been using a single pair of the USB test leads pretty extensively, and one of the spring-loaded probe ends has a habit of sticking in the retracted position. I'm not sure why, but it doesn't affect use of the tester significantly. A drop of mineral oil might fix it right up. I just wish the testers had an even larger capacity for my specific project needs. A 10-bay tester that could accommodate D-cells would be awesome!

  • What device/application do you use this with? Testing cells before building battery packs

So far so good

The charger gives me confidence that the cells are being charged properly, and I can test them to sort out the ones that have might have some issues, before stringing them together to make a battery pack. I've only had this product for a few days, but so far it seems to be working fine. My only complaints would be: 1) That if you move it around, the power might cut out briefly. the DC power plug into the unit doesn't take any tugs to the side at all. If you are testing cells, this could set you back a few hours. 2) I wish it had a function to charge/discharge for storage. I have many cells that I probably wont use for a few months, it would be nice to test them and then return them to 50-60% charge for storage...

  • What device/application do you use this with? IJoy Limitless Lux

Great charger

Got this for a birthday present last week. This is a nice charger. I put 4 26650 batts in it and didn't break a sweat. I had some Samsung 30Q's that were dead from being in a mod for a month. Just forgot about them. This thing charged them right up and they didn't even get warm I have a couple of Nitecore I4's that would not recharge them. This Xtar runs much cooler when charging than the Nitecores do. Can start using my charging bag again. Haven't got into all the features yet but looking forward to it.
