Frequently Asked Questions

What makes this a semi-solid-state battery?

Unlike traditional lithium-ion batteries that use liquid electrolytes, our semi-solid-state design incorporates a gel-like or semi-solid electrolyte. This significantly improves safety by reducing the risk of leakage and thermal runaway, while also enhancing structural stability and cycle life.

What is the recommended charging procedure?

We recommend using a dedicated Li-ion charger with CC-CV (constant current-constant voltage) mode. The standard charge current is 15A (0.5C) with a cut-off voltage of 29.4V and a termination current of 0.02C. Always ensure the charger is compatible with 7-series (7S) lithium-ion battery packs.

What is the typical cycle life?

Under standard testing conditions (1C charge, 3C discharge to 17.5V), the battery retains over 80% of its minimum capacity after 300 cycles. Proper usage and storage will further extend its lifespan.

How should I store the battery for long periods?

For long-term storage (up to 1 year), keep the battery at a 50% state of charge (SOC) — approximately 25.2V to 26.95V pack voltage — in a cool, dry place at 25±3℃ and humidity ≤75%RH. Recharge every 3 months to prevent over-discharge.

What safety features are integrated?

This pack is designed with robust safety in mind, passing rigorous tests including overcharge, short circuit, forced discharge, vibration, and drop tests without fire or explosion. However, it is essential to use a compatible protection circuit and follow all user guidelines to ensure safe operation.

Can I use this battery with my existing drone?

This pack is designed for professional UAVs requiring a 25.2V (7S) power source with high current capability. Before purchasing, please verify that your drone's power system, flight controller, and battery compartment are compatible with the pack's dimensions (633.5mm length) and electrical specifications.

What is the warranty policy?

Jianheng provides a 6-month warranty from the date of shipment. The warranty covers defects in materials and workmanship under normal use. It does not cover issues resulting from improper handling, mismatched components, or operation outside the specified parameters.

How do I dispose of this battery?

Do not dispose of in fire or general waste. Before disposal, fully discharge the battery to 17.5V or less, insulate the terminals with tape, and recycle it in accordance with local regulations for lithium-ion batteries.
