WhoopStor V3 6 Ports 1S LiPo Battery Storage Charger and Discharger with LCD Display Tiny Whoop Charger with PH2.0 and BT2.0 Connectors

I was using a really cheap low dollar 2 port 1s charger until this showed up. As expected, the cheap charger was not doing right by my batteries. This charger discharged some of my batteries and brought them up to optimum charge voltage. 6-at-a-time makes it really painless after flying 13 batteries after work. The charger beeps as each battery is re-charged. As advertised. Happy with the purchase. Fair value for the ease of use and convenience.

Fantastic little charger. You can tell from the design features that the designers actually use these things. It can be powered from the wall, USB, or an XT-60 with 2S-6S batteries. It supports the latest BT 2.0 connector (think tiny XT-60) and comes with 6 PH 2.0 adapter cables, so you can make converter cables for XT-30, JST, JST-DS LOSI 2.0MM, or whatever you need. So I can use it for my whoops (PH 2.0 and XT-30), mini warbirds (JST-DS LOSI 2.0MM), 1S UMX, etc.Best feature? It's got a variable voltage (note that only storage and full voltage options are provided), which is a feature that in retrospect I cannot believe all 1S chargers don't have. 1S batteries need love too! What's even better, unlike many chargers, you don't have to tell it whether to be in "charge mode" or "storage mode": it just takes all batteries to whatever voltage you have set. The way I use it is to set the voltage at 4.2 and continuously cycle batteries through during my tiny whoop flying session. Then when I'm done flying for the day, I throw all my batteries on the charger set at 3.8; the ones I used will be charged up to storage, and the ones I didn't will be discharged down to storage.My only gripe is that the color screen is rather small and hard to read, especially in the sunlight. But that's a minor complaint. This is by far my favorite 1S charger!

No issues. Been using a few years now

If you have lots of 1s batteries, you need this charger.

Keeps you going, usb-c or lipo work equally well, storage charging feature is great, no substitute.

I love this charger. It charges six packs simultaneously. The charge circuits are almost completely independent and hot pluggable. If you're charging a bunch of cells, you can put six batteries in, start charging, and as each one finishes pull it out and put a new pack in place. It'll also discharge. It supports both standard lipos and HV (not at the same time) by offering four target voltages (3.8, 3.85, 4.2, 4.35).You can power it from a brick with a barrel plug, DC via XT60, and USB-C PD. The latter is wonderful for field use as you can run it off a power brick provided the brick supports PD. Unfortunately, there does appear to be some sort of issue with the implementation as it is incompatible with one of my wall USB PD devices. I believe the issue is with the Whoopstor rather than the power supply, but it isn't possible to isolate as the power supply works with every other device I have tried it with and the charger has worked with every other power supply I've tried it with.There are a couple, minor, shortcomings with the device, though. First, there's no way to independently set the charge rate on each port. Honestly, most of the time you probably wouldn't want to, but if you are trying to charge batteries of mixed sizes simultaneously (which this charger supports, unlike many multi-chargers) you'll have to settle for a charge rate that's safe for the smallest capacity. Second minor issue, minimum charge rate is 0.3A. That's fine for most batteries, but some of the tiny packs used by some RC fixed wings are in the 150-200mAh range and are only rated for 1C charge. Third, there's no mAh charged display that I've been able to find, which means you'll need to charge using a different mechanism if you're trying to calibrate an FC.

I love this charger, each port is independent in that you can start- stop catching as needed. Amps go way higher than needed when using lipo. Read the manual on amps do research, you don't want to thrash your batteries.

Awesome charger and great price. It charges 6, 1s batters at once and lets you set the voltage to what you need. Also has the awesome feature of being powered by a larger battery via the xt60 plug. Overall you won't find a better charger than this.
