Storage Charger and Discharger
VIFLY WhoopStor 3 is a combination of charger and discharger. It has 4 target voltages (3.8V/3.85V/4.2V/4.35V), set your target voltage like 3.8V (LiPo Storage Voltage), it will start the charging or discharging process automatically when the battery is lower or higher than 3.8V. So it provides maximum protection for your delicate 1S cells. It stops exactly at the target voltage every time, preventing overcharge or over-discharge.
Memory Function
VIFLY WhoopStor 3 added the memory feature of remembering last time settings, no need to set the charge current every time you turn it on.
Advanced Cooling System
The VIFLY WhoopStor 3 features an integrated cooling system that efficiently dissipates heat during charging and discharging. This prevents overheating, ensures stable performance, and prolongs the lifespan of both the charger and your LiPo batteries. Even when all six ports are in use, the smart thermal design keeps temperatures under control for safe and reliable operation.
Multiple Power Inputs (Type-C, XT60, DC)
VIFLY 1S LiPo charger supports Type-C, XT60 and DC power input. Type-C used PD and QC protocol that supports fast charge at 9V and 12V, but it not supports regular 5V USB charge.Whether you are in the workshop or at the field, the WhoopStor 3 has you covered.
VIFLY NEW WhoopStor 3 1S Charger Review & Guide
Anyone flying indoor micro FPV drones quickly runs into the same frustrating issue: managing a mountain of 1S LiPo batteries. Standard single-port chargers are slow, lack proper storage functions, and leaving fully charged batteries sitting around causes rapid cell degradation, capacity loss, and swelling. The VIFLY NEW WhoopStor 3 solves this completely. As the industry's first dedicated 6-channel 1S charger featuring built-in charging, discharging, and automatic storage maintenance, it has quickly become an essential tool for micro drone pilots. In this product guide, we review its core features, compatibility, and hardware setup best practices to help you get the most out of your gear.
Product Review: Built for Performance & Battery Care
The defining feature of the NEW WhoopStor 3 is its intelligent, automated battery maintenance system. Unlike basic chargers that only pump power into a cell, the WhoopStor 3 manages voltage in both directions. Automated Storage Mode: It includes four preset target voltages—Standard LiPo (4.20V), High-Voltage LiHV (4.35V), and their dedicated storage targets (3.80V for LiPo and 3.85V for LiHV). If your batteries are fully charged after an unused session, it safely discharges them down to storage level. If they are drained, it automatically charges them up to the target voltage.
6 Independent Channels: Each port operates completely separately. You can plug in batteries with different remaining voltages or capacities simultaneously without cross-interference or balance issues.
Fine Current Tuning: The charging current is adjustable from 0.3A to 1.3A in precise increments. This allows you to safely trickle-charge tiny 300mAh packs or fast-charge high-capacity 850mAh racing cells following safe 2C charging standards.
HD Display & Quiet Cooling: The high-definition color LCD screen provides individual real-time readouts for voltage and current across all six channels. Meanwhile, an internal quiet fan and optimized airflow keep temperatures low during heavy, simultaneous 6-port discharging.
Application Scenarios & Broad Compatibility
Designed to handle virtually all 1S micro FPV gear on the market, the WhoopStor 3 seamlessly adapts to your flying environment:
Native Dual Connector Board: Every single channel features side-by-side PH2.0 and BT2.0 ports. You can plug in batteries for the BetaFPV Meteor series, Happymodel Mobula6/7, Cetus X, and custom 1S toothpick builds directly without clunky adapter cables.
Triple Power Input Options: You are never tethered to a wall socket. It supports Type-C (PD/QC fast charge) for desktop use, a DC barrel jack (6V–26V) for workshop power supplies, and an XT60 port. The XT60 input lets you plug in a large 2S–6S LiPo battery at the flying field to recharge your 1S packs on the go.

FAQFeel free to ask us any questions
Ｑ：Can I charge different capacity 1S batteries at the same time?
Ａ：Yes. The WhoopStor 3 features six fully independent charging ports, so you can charge batteries of different capacities and voltages simultaneously. Each port operates separately, allowing you to plug and unplug batteries at any time without affecting the others.
Ｑ：What is the storage function and why is it important?
Ａ：The storage function automatically charges or discharges your battery to the optimal storage voltage (3.80V or 3.85V). Storing LiPo batteries at the correct voltage helps extend battery lifespan, maintain performance, and reduce safety risks when batteries are not in use.
Q: Why is the WhoopStor 3 considered the best charger for Whoop pilots?
A: It is the first 1S charger to offer a true storage mode. Please enjoy the ability to both charge and discharge your batteries to the ideal storage voltage, significantly prolonging your battery life.
Q: Can I charge different types of 1S batteries at the same time?
A: Yes, you can! Please note that all 6 ports are fully independent. You can mix LiPo and LiHV batteries or different capacities without any interference between ports.
Q: Does this charger support the newer BT2.0 connectors?
A: Absolutely. Each port features both PH2.0 and BT2.0 connectors. Please feel free to use your preferred connector type directly without needing extra adapter cables.
