VIFLY WhoopStor V3 6-Port 1S LiPo Battery Storage Charger

This is probably the best investment you can make for your whoop drone. Sure, it's a very expensive charger, almost as much as the charger you bought for your 5-inch FPV. But think of it this way: it'll eventually pay for itself. If you learn to manage your whoop batteries properly, you can dial in your own settings to protect them from overcharging and put them into a proper storage state. That makes your batteries last so much longer, which keeps you from constantly buying new ones. Over time, that adds up. Calling it a "fast charger" is a little weird, because you set how fast you want it to charge. If you want to stay within safe limits, you just keep it dialed in right. Power options are plenty too. You can run it off a USB-C fast charger or a 6S battery pack. Pair it with a 6S battery and you can take this thing anywhere, because it's seriously compact. It's not too heavy, and it'll keep charging even when there's no wall power around. The LCD gives you stats on each battery, shows which ones are charging and which are ready, and there's a loud beep when they're done. It's a must-have if you find yourself flying your whoop multiple times a day. So yeah, sure, it's a lot to spend on a charger that can pretty much only charge one type of battery. But it charges that one type of battery pretty darn good. So, 5 stars. It's an investment up front, but the battery savings, the portability, and the smart charging make it more than worth it for anyone serious about flying whoops.

Charger works great with my Lava 550's, Lava 300's and Tattu 300's. I charge them all at 1amp to 4.35v, sometimes with a mix of the 3 different types. The beeper on it is audible, but not annoying, and lets you know when a battery is fully charged or discharged. This is nice because if I'm charging a mix of 300mah and 550mah, I know that a 300 is done, and can throw another one on. You can also mute the beeper by long pressing the "Voltage Set" button. It seems the charger "stays" charging even if all batteries are in the "ok/done" state, so you can just hot swap a new battery on without needing to restart the charging. Same goes with discharging. Discharging is done at 0.5A, however the back of the charger says 0.3A, and the internal fan will kick on occasionally, especially if doing multiple batteries at once. The screen is small, but crisp, and easy to read. There's a lot of nice features packed into a charger at this price! No power adapter is included, so make sure you have one that is rated at least 45 watts! If the adapter isn't sufficient, it will let you know when it boots up with a warning message.

Perfect for tiny whoops. I have cycled A30 flywoo and betafpv lava II 1s batteries with no issues. The storage function is great and zero issues charging multiple battery types, plugging in a battery of the same type while others are charging etc. Not sure if there is any other charger with a good display and ease of use like this one. Probably my 5-6th Vifly product and have yet to have an issue with any, so based on my experience, they have good internal QC. Highly recommend after about 30 charge and storage cycles.

If you fly tinywhoop drones or anything else with 1s batteries; This one is an absolute must have! - Impressive functionality and versatility; I was already pleased with the 6 independent bays and the ease of having multiple power inputs (DC, usb-c, or XT60), but having a live voltage read out on a color display; the ability to easily set them to a storage voltage; adjustable current settings (.3a - 1.3a) and a sleek compact design (fits well alongside the other accessories in my case) makes this one my favorite choice for keeping all of my 1s batteries running full charge and in the best condition to keep getting the longest lasting battery life out of them! - No more worrying about keeping them in a certain order depending on charge level; Honestly decent price point considering anything else on the market; Excellent charge rate (especially when using my 65w DJI usb-c charger input) - Hands down would recommend and would definitely get this one again! 11/10

Best 1s portable charger money can buy

I really wanted to like this and the mini-screens are great but what I am missing is the lights from the previous version. I can at a glance see if any of the channels are still charging or have finished. This new version you have to get very close and read the screen and look for a very small icon of either orange on white background or green on white background for each of the 6 boxes. I feel this is a big step back for that one point otherwise the screens are kinda cool. Another point on old version vs new, there used to be a physical switch to flip for storage mode and 4.2 vs 4.35 HV. It was stupidly quick and efficient but now it is a series of mashing the 2 buttons until you figure out the right combination to turn on storage mode or HV/not. And no you still can't have some HV and some not, it's all or nothing in both versions. Last point on the new version is that it is significantly taller/thicker than the previous version. I am not sure why it needed to be so much bigger as the only change is the addition of a slightly bigger color screen. The move to put both connectors types on the top next to each other is either here nor there. I have used both of them and it's not really a positive, it works both ways and It's just different, not necessarily better or worse. They both support both types of connectors and no reason for either version over the other on this aspect. Overall it is a very capable charger and really the best out there for 1S batteries....except for their previous version. For now it has gone on the shelf and I am still using the older version as it is functionally identical and the design choices made in the newer version I feel are a step back. I would personally recommend looking for the older version instead if possible as it really is superior.

This appears to be a well-made charger for small batteries used in RC planes and similar devices. The readout is very clear showing the input voltage and the output and current to each battery being charged. It also has provisions for discharging batteries to a pre-determined storage level. It does require a pretty hefty power supply, included literature recommends a 40W supply working at something like 9 to 24 V. It has a USB C port but a conventional USB power supply will not be sufficient. However, it is not compatible with PH 1.25 Ultra Micro batteries such as used in my Ultra Micro Blade Nano s3. That is, the connectors on the device won't fit these small batteries. Yes, I only figured this out after purchasing the device! The description of this charger is pretty clear about what type of battery connectors it provides, so its entirely my fault so I won't be trying to return it, and maybe someday I'll get a plane that uses compatible batteries. Moral of the story -- read the fine print!

Best 1s charger out there. Fast shipping on Amazon was great compared to other sites. Allows me to feel comfortable charging my LiPOs and up to 6 at one time for a tiny whoop is plenty to keep me in the air as others charge up. Very easy to use and powering it with a charging cord for my phone was a big plus and makes finding a charging cord for it easy and almost impossible to forget.

The VIFLY WhoopStor 3 is the best in its area for charging 1s lipos, although it does have some faults which you should consider before purchasing. Its benefits include it able to charge 6 batteries at once (something I find very useful as I have 5 lipos), using a USB C input to charge, resulting in it being compatible with powerbanks, (if they have a high enough output power), or a wide range of chargers. The VIFLY WhoopStor 3 also charges relatively quickly, with the charging amperage and voltage being able to be customised. Despite the positives, you should keep in mind that it can't charge batteries some batteries, as one of my outputs broke after 2 days. So, if you would like a customisable and efficient product, choose the VIFLY WhoopStor 3. I would consider it to be the best 1s battery charger.

Great charger

Great product. Charges well no issues were found.

Works how I expected it to, takes about 30 to 40 minutes to fully charge 6 batteries at full power to 4.35v. it's small which is convenient.
