Overview: Vifly ToothStor 4-Channel 2S LiPo Battery Charger


On this assessment I’ll try the VIFLY ToothStor 2S LiPo charger. This charger boasts user-friendly options, portability, and the reliability anticipated from VIFLY’s respected lineup. Good for FPV pilots largely flying 2S FPV drones, the ToothStor guarantees to make charging extra environment friendly.

What’s the ToothStor Charger?

The Vifly ToothStor is a specialised charger that caters completely to 2S LiPo batteries.

Its design is tailor-made primarily for batteries geared up with BT3.0 connectors – on the time of writing, solely BetaFPV provides these batteries. See my publish about what BT3.0 is: https://oscarliang.com/betafpv-bt3-0-connector/. Be aware that the ToothStor additionally accommodates regular 2S batteries with commonplace steadiness leads (XH2.54), and conveniently eliminating the necessity to join the XT30 discharge lead.

Admittedly, its unique assist for 2S batteries could appear restrictive when in comparison with a traditional sensible charger that usually helps 1S to 6S batteries. Nevertheless, the ToothStor’s capability to cost 4 batteries concurrently makes up for this limitation by providing a extra environment friendly charging expertise. For drone pilots who primarily fly 2S, this charger could possibly be an enormous time-saver within the discipline.

Now, let’s get into the assessment.

The place to Purchase?

Construct High quality

The ToothStor’s casing is powerful, inheriting its construct high quality from the WhoopStor sequence. Having used VIFLY’s chargers for the previous few years, their reliability has been constant – they merely work with out fuss. And the ToothStor continues this custom, performing reliably throughout my checks.

It provides compatibility with the generally used XH 2.45 3-pin connectors (steadiness lead), in addition to with the newer BT3.0 connectors from BetaFPV.

Versatility in Energy Choices

The place the ToothStor actually stands out is in its energy versatility. The inclusion of an XT60 connector permits for a broad enter vary, from a 2S to a 6S battery. For these with entry to a PD energy supply, the USB-C enter is a handy characteristic carried over from the WhoopStor V3. The flexibility to energy from a USB energy financial institution is a big plus, particularly for pilots who have to cost their batteries in numerous places.

Consumer Expertise: Charging Made Easy

Utilizing the ToothStor was a breeze. The person interface, managed by simply two buttons, is intuitive, even for novices.

When connecting batteries, every port accepts both a BT3.0 or an XH2.54 connector (steadiness lead). To keep up security and keep away from the dangers related to parallel charging, just one sort of connector needs to be used per port.

The 4 charging channels function independently, which is a big benefit. This lets you cost batteries with totally different voltages and capacities concurrently, a characteristic not usually attainable with parallel charging. Whereas the channels share the identical finish voltage and cost present settings, which might’t be adjusted individually, this shared setting does streamline the charging course of.

Biking by way of the tip voltage per cell is completed by urgent the best button, providing 4 choices:

Choosing the present is simply as easy, with choices biking from 0.2A as much as 1.5A. If you should lower the present, it requires biking as much as the utmost first after which again all the way down to the minimal setting. If you should cut back the cost present, I like to recommend stopping all 4 channels and restarting the method to set the specified present.

To start out or cease charging, lengthy press the left button. Upon beginning the cost, the cooling fan kicked in after a couple of minute or two, it’s comparatively quiet in comparison with sensible chargers this dimension.

A built-in buzzer alerts when the cost cycle begins and ends, however it may be turned off in the event you favor a silent operation. To mute/unmute the charger, lengthy press the best button.

Limitations and Concerns

When charging on the ToothStor’s most present of 1.5A throughout all channels, the charger attracts an enter energy of 56W, contemplating losses. To make sure security and optimum efficiency, Vifly recommends utilizing a 65W energy adapter. For these trying to make the most of the USB-C energy possibility, a sturdy energy adapter, such because the Anker 65W, is advisable, get it from Amazon: https://amzn.to/3VE3yro.

The charger additionally features a discharging characteristic, which turns out to be useful for taking absolutely charged batteries to a storage cost. The discharging price is considerably gradual at solely 0.2A, however on condition that 2S batteries usually have a decrease capability, it’s not that unhealthy. As an example, discharging a 2S 450mAh battery to three.80V from a full cost would take below an hour, and you are able to do 4 batteries directly.

There’s, nevertheless, a minor discrepancy with the accuracy in reaching the focused finish voltage. In my expertise, when discharging to three.85V, the method stops with the cells at about 3.87V to three.88V. Equally, when charging to 4.20V, the charger tends to cease prematurely at roughly 4.19V. The identical occurs to all ports. Whereas it’s not essentially a security concern—because it doesn’t result in overcharging—the precision might sure profit from some enchancment.

Voltage Accuracy

I examined the charger’s accuracy with a calibrated multimeter. The outcomes had been passable, exhibiting nice consistency between the charger’s readings and the digital multimeter.

Supply Charger Report DDM
Port1 Cell1 4.19 4.191
Port1 Cell2 4.18 4.186
Port2 Cell1 4.19 4.191

Port3 Cell2 4.18 4.186
Port4 Cell1 4.19 4.191
Port4 Cell2 4.18 4.186

The slight discrepancies are negligible, reassuring me of the charger’s voltage accuracy.

Ultimate Ideas

The VIFLY ToothStor can be a useful device for individuals who fly 2S FPV drones, particularly in the event you use BT3.0 batteries. Its capability to cost a number of 2S batteries concurrently and individually, coupled with the benefit of use and a number of energy enter choices, makes it a standout product.

You should purchase the Vifly ToothStor charger by way of AliExpress: https://s.click on.aliexpress.com/e/_DDvdcO1.

Nevertheless it’s a distinct segment product – it doesn’t assist some other batteries besides 2S. It’s not a one-size-fits-all resolution, however it doesn’t goal to be. Vifly isn’t making an attempt to reinvent the wheel with this product. As an alternative, they’re refining it, making certain that charging 2S batteries is as clean and environment friendly as attainable.
