LiPo battery compatibility is more than capacity and connector shape. Chemistry, cell count, voltage, polarity, dimensions, mass, current requirements and the aircraft manufacturer’s approved range must agree. When a seller label and model manual conflict, stop and verify before connecting the pack.
Compatibility checklist
| Check | Why it matters |
|---|---|
| Chemistry and cell count | Determines the correct charger program and operating voltage range |
| Connector and polarity | Matching housings can still be wired differently |
| Dimensions and retention | The pack must fit without crushing, movement or damaged leads |
| Mass and center of gravity | A heavier pack can change handling even when it fits |
| Capacity/current requirements | Must remain within the aircraft, battery and charger manufacturers’ limits |
Inspect before every charge and flight
Do not use a pack with swelling, impact damage, puncture, damaged insulation, exposed conductors, loose connectors, unusual odor, heat or manufacturer-defined cell problems. Isolate a damaged pack away from combustible material and follow the manufacturer and local hazardous-waste guidance.
Charging workflow
- Read the battery and charger labels and manuals.
- Select the program that matches the exact battery chemistry and cell count.
- Verify connector polarity before connection.
- Charge in a suitable non-combustible location, away from exits and combustible material.
- Remain present and able to disconnect safely.
- Stop for swelling, heat, odor, smoke, damage or charger errors.
Storage and transport
Follow the battery maker’s storage-voltage and temperature guidance. Protect terminals from short circuits, prevent crushing or puncture, and keep packs in a cool, dry location away from children, pets and combustible material. Check current carrier rules before transporting lithium batteries.
Model-specific verification notes
The current K170 and C032 parts pages contain many coded variants, but a code alone does not establish battery chemistry, voltage, capacity, dimensions or polarity. The current C170 Apache parts listing does not show a clearly named battery variant. For all three models, use the original battery label and aircraft manual as the controlling sources; contact support when those details cannot be confirmed.
Battery ownership record
Assign each pack an identifier and record purchase date, aircraft, visible condition and unusual charger messages. Record measured data only with appropriate equipment and consistent conditions. Do not turn an estimate into a published flight-time or health claim.
