About this item

  • 300A POWER FOR HIGH-DEMAND BATTERY BANKS – Built around a 300A continuous-current platform for 3S-8S LiFePO4/Li-ion and 7S-8S LTO packs. Ideal for 4S 12V or 8S 24V systems where an ordinary low-current BMS could become the bottleneck
  • 2A ACTIVE BALANCING FOR LARGE CELLS – When balancing is enabled, energy moves from higher-voltage cells to lower-voltage cells, helping reduce cell drift, preserve usable pack capacity and maintain more consistent performance across high-capacity battery banks
  • SEE YOUR BATTERY BEFORE PROBLEMS GROW – Built-in Bluetooth puts individual cell voltage, total voltage, current, temperature, SOC and alerts in the JK BMS app. Adjust supported protection and balancing parameters to match your battery design
  • CONFIGURABLE PROTECTION FOR REAL-WORLD LOADS – Monitors overcharge, over-discharge, overcurrent, short circuit and temperature conditions. Protection settings can be matched to your cells, charger, inverter and operating environment
  • VERIFY THE BUILD AND AVOID THE WRONG BMS – Intended for 3S-8S battery systems; not for 36V/48V golf carts or 16S/20S/24S packs. Match sustained 300A use with suitable cells, cables, terminals, fuse or breaker, enclosure and thermal design

FAQ

What types of drones and accessories does Flyvora offer?

Flyvora offers camera drones, GPS drones, FPV racing drones, mini and beginner models, replacement propellers, batteries, chargers, controllers, camera components, cases, landing equipment, and repair supplies. Product availability may change over time.

How can I confirm that an accessory is compatible with my drone?

Check the exact drone brand, model number, hardware version, dimensions, connector, voltage, battery type, and other specifications shown on the product page. Similar-looking parts may not be interchangeable. Contact us before ordering if compatibility is unclear.

Do I need to register my drone with the FAA?

Registration requirements depend on the drone’s weight, equipment, and intended use. Certain drones operated in the United States must be registered and may need to comply with Remote ID requirements. Review current information at the official FAA website before flying.

How long does order processing and delivery take?

Orders are generally processed within 1–3 business days. Estimated delivery within the contiguous United States is usually 5–10 business days after shipment. Holidays, weather, carrier disruptions, address issues, and lithium-battery restrictions may cause delays.

How can I track my order?

When tracking is available, we will email you a shipping confirmation containing the tracking number and carrier information. Tracking may take 2–5 business days to display its first update after the shipping label is created.

Can I change or cancel my order?

Contact us as soon as possible after placing your order. We recommend submitting change or cancellation requests within 12 hours. Changes cannot be guaranteed after processing or fulfillment has begun.

What is Flyvora’s return policy?

Eligible products may generally be returned within 30 calendar days after delivery. Items must be unused, unflown, uninstalled, and returned with the original packaging and included components. Contact us for authorization before shipping any return.

How should I safely charge and store drone batteries?

Use only compatible batteries and charging equipment, follow the manufacturer’s instructions, and charge on an appropriate surface away from combustible materials. Stop using batteries that are swollen, leaking, punctured, unusually hot, or damaged. Contact us before attempting to return a damaged lithium battery.
