On this overview 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. Excellent for FPV pilots principally 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 solely to 2S LiPo batteries.

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

Admittedly, its unique help for 2S batteries could appear restrictive when in comparison with a traditional good charger that usually helps 1S to 6S batteries. Nevertheless, the ToothStor’s means 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 may very well be an enormous time-saver within the area.

Now, let’s get into the overview.

The place to Purchase?

The Vifly ToothStor charger is accessible for buy on AliExpress: https://s.click on.aliexpress.com/e/_DDvdcO1.

In case you want to energy this charger through USB-C, it is best to take into account getting an influence adapter like this, Anker 65W: https://amzn.to/3VE3yro.

The package deal features a easy handbook and a USB-C cable that powers the charger and likewise for firmware updates.

Function Highlights

• 4 Particular person Charging Ports: Concurrently stability cost as much as 4 2S batteries, not like parallel charging, there’s no have to match the voltages or capacities of the batteries.
• Colourful LCD Display with Intuitive Interface: Outfitted with shade LCD display screen, the ToothStor shows charging statuses with readability, providing a user-friendly expertise.
• Compatibility with XH2.54 and BT3.0 Batteries: Cater to a variety of 2S batteries, guaranteeing broad compatibility.
• Environment friendly Warmth Dissipation: A mixture of a fan and a big warmth sink effectively dissipates warmth, enhancing the charger’s efficiency and pace.
• Versatile Energy Enter Choices: The charger helps a number of energy inputs, together with XT60 and Sort-C with PD3.0.
• Handy Reminiscence Perform: The ToothStor remembers your final used settings, streamlining the setup course of for subsequent charging classes.
• Buzzer Notifications: The built-in buzzer notifies you when a charging cycle is full, which you’ll be able to disable should you want a quieter atmosphere.

Construct High quality

The ToothStor’s casing is strong, 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 presents compatibility with the generally used XH 2.45 3-pin connectors (stability 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 major plus, particularly for pilots who have to cost their batteries in varied areas.

Consumer Expertise: Charging Made Easy

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

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

The 4 charging channels function independently, which is a major benefit. This lets you cost batteries with completely different voltages and capacities concurrently, a characteristic not usually potential 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 the top voltage per cell is finished by urgent the suitable button, providing 4 choices:

Choosing the present is simply as simple, with choices biking from 0.2A as much as 1.5A. If you must 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 must scale back the cost present, I like to recommend stopping all 4 channels and restarting the method to set the specified present.

To begin or cease charging, lengthy press the left button. Upon beginning the cost, the cooling fan kicked in after a few minute or two, it’s comparatively quiet in comparison with good chargers this measurement.

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

Limitations and Issues

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 strong 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 is useful for taking absolutely charged batteries to a storage cost. The discharging fee is considerably sluggish at solely 0.2A, however provided that 2S batteries usually have a decrease capability, it’s not that dangerous. As an instance, discharging a 2S 450mAh battery to three.80V from a full cost would take underneath an hour, and you are able to do 4 batteries directly.

There may be, 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 may sure profit from some enchancment.

Voltage Accuracy

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

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

Last Ideas

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

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

Nevertheless it’s a distinct segment product – it doesn’t help another batteries besides 2S. It’s not a one-size-fits-all answer, nevertheless it doesn’t purpose to be. Vifly isn’t attempting to reinvent the wheel with this product. As a substitute, they’re refining it, guaranteeing that charging 2S batteries is as clean and environment friendly as potential.
