VIFLY WhoopStor 3 6-Port 1S LiPo Storage Charger & Discharger is a powerful all-in-one charging solution designed specifically for 1S LiPo and LiHV batteries. Featuring six fully independent ports, adjustable charge current (0.3A–1.3A), and automatic storage mode, it allows you to safely charge, discharge, or bring batteries to optimal storage voltage with ease.With multiple input options including XT60, DC, and USB-C (PD3.0), it delivers flexible power compatibility for both field and workshop use. The built-in cooling system ensures stable operation even when all ports are active, protecting both your charger and batteries. Smart, efficient, and compact — it’s an essential tool for whoop pilots and FPV enthusiasts.
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.

FAQFeel free to ask us any questions
ASK A QUESTION
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.
