Product Description
Instructions for the Charger Indicator Light
When the charger establishes contact with the battery, it first detects the battery voltage and then supplies the appropriate charging current and voltage, during which the LED indicator turns red. Once the charger's internal IC determines that the battery is fully charged, the indicator switches to green.
LED Indicator Guide:
Solid Red Light: The charger is actively charging your battery. It automatically supplies the right power after checking the battery status.
Solid Green Light: Your battery is fully charged. The internal smart chip has detected the full charge and stopped the process to protect your battery.

- Reviewed in Canada on January 6, 2026Verified PurchaseWorks perfectly and is way cheaper than the original batteries
- Reviewed in Canada on December 30, 2025I picked up this battery and charger set because I wanted extra power for longer shooting days without worrying about running out mid clip. The batteries charged quickly in the case and it was convenient being able to charge everything with a single USB C cable. I rotated through the batteries during a day of filming and they held up well with consistent performance. The charging case kept everything organized and was easy to toss into a small gear bag. Overall it was a solid setup that made shooting more relaxed knowing I always had charged batteries ready.
- Reviewed in Canada on February 6, 2026Verified PurchaseGood batteries. No issues 2 months in. Work as advertised. Charger box looks and feels well built. Not crappie. I like K&F for sure. They stand by there products. If you have an issue they will see it here and reach out. Good company
- Reviewed in Canada on December 15, 2025You really can’t go wrong with this company’s products. I’ve bought some products from them in the past and found them to be very well-made and consistently good quality. Not only are you getting three decent quality aftermarket batteries that definitely will work with both the Osmo action five as well as the DJI 360 but you get a very good charging case too. I prefer to put the batteries in a protective case rather than loosely in a caring bag so this charging case stuff definitely comes in handy. A relatively short USB-C charging cable is included, but any cable will work if you find this is too short. The case has LED indicators so you know from the outside whether the batteries are charged or not. That is a very handy feature to have. There was no issue with compatibility with the action five camera and it’s great to have extra batteries from a reliable company.The media could not be loaded.
- Reviewed in Canada on March 16, 2026Verified PurchaseI purchased this kit under the impression that the charging case functioned as a standalone power bank (charging the batteries on the go without being plugged in). To clarify for other buyers: it does not. The case requires a constant USB-C power source to charge the batteries, making it functionally identical to the official DJI charging case.
Pros
Capacity: The 2100mAh batteries provide a noticeable boost over the standard capacity.
Performance: Reliability and runtime have been remarkably good so far with no compatibility issues.
Value: Getting three high-capacity batteries and a dedicated charger in one pack is a solid deal.
Cons
Misleading Case Design: If you are looking for a case with an internal "bank" to charge batteries in your bag, this isn't it. It is strictly a powered charging hub.
Final Verdict: Buy this for the excellent batteries, not for the case. As long as you have a wall outlet or an actual power bank to plug this into, the performance of the cells makes the kit worth it.
- Reviewed in Canada on March 3, 2026Verified PurchaseI recently ordered this pack of 3 batteries and the charger.
I tested them at -10°C, and they discharged extremely quickly — one after another. While my original camera battery continued working without any issues in the same conditions, I had already replaced all of these new batteries, and they drained even faster.
They do not perform well in cold weather and are not reliable for outdoor use in winter conditions. I would not recommend them if you plan to use your camera in low temperatures.
- Reviewed in Canada on March 16, 2026Verified PurchaseRecordtimes are very similar to 1770 mah cells that comes with the DJI action 4... as long as the temperature is above super low freezing. At around -25C, the runtimes do decrease considerably, but overall it's not too bad, and anything above around -10C there is no difference to the original battery. Charging case feels lightweight and somewhat thin but otherwise fine, and charges the official batteries well so I don't have any issue with it.

SretanReviewed in France on January 17, 20265.0 out of 5 stars La qualité K&F !
Une fois de plus, K&F nous propose du matériel de très grande qualité. Ce n'est plus une surprise maintenant que je commence à posséder pas mal de matériel de cette marque, jamais déçu, on fait fasse à une qualité globale plus que satisfaisante. En ce qui concerne mon matériel photo, je me tourne toujours vers K&F en plus d'une autre marque.
Un bon kit de batterie pour charger son appareil lorsqu'on part sur une journée.
La fiabilité de la marque permet d'utiliser sa batterie sans craindre d'endommager ses appareils (équivalent aux DJI)
Le tout est compact et tien bien dans peu de place, facile à mettre dans son sac photo ou même dans une banane.
L'ensemble est résistant et robuste et permet une tranquillité d'esprit.
Les voyants permettent de suivre la charge des batteries.
En bref je recommande, rapport qualité prix et fiabilité K&F, on peut y aller les yeux fermés !

Víctor C.Reviewed in Spain on February 1, 20265.0 out of 5 stars Imprescindibles para tu Osmo Action 3, 4, 5 pro o 6. Con + capacidad que la origianl
Tengo una osmo Action 4 de DJI y estoy encantado con ella. La llevo a todos mis viajes para grabar a mi familia, a mí mismo y haciendo deporte. La suelo usar mucho por lo que con una batería no tengo para todo el día. Con este estuche para 3 baterías tengo de sobra para un fin de semana completo.The media could not be loaded.
Este pack trae 3 baterías compatibles con la Osmo Action 3, 4, 5 y 6. Es totalmente compatible y funciona a la perfección. Comparándola con la original, es una batería con mayor capacidad. La original tiene 1770 mAh y estas de la marca K&F tiene 2100. A efectos prácticos, tengo que decir que es cierto que dura o lo mismo o más. También depende mucho de la calidad a la que grabes y los FPS que uses, pero esos casi 400 mAh de diferencia, hace que duren un poco más.
Sus materiales se sienten y se ven de buena calidad. Nadie diría que no es una original por sus materiales de construcción. El cargador también es robusto y con un plástico de calidad. En la parte delantera tiene 3 luces que indica el estado de carga de cada una de las baterías. Si está en rojo es que se está cargando, y si está en verde es que o está cargada, o no está la batería conectada.
La caja de carga no tiene batería propia, por lo que al guardar ahí las baterías no se cargan solas.
Algo que me ha gustado mucho, es que en la tapa, tiene dos ranuras para guardar dos tarjetas micro SD. Me hubiese gustado que también se pudiera guardar el cable USB tipo C que trae para su carga, pero no hay espacio para él.
Las baterías se calienta a una temperatura normal, como las originales. Su relación calidad-precio me parecen fabulosas. Este pack de 3 baterías + el cargador, tiene un precio muy similar al de una sola batería original, por lo que el precio es rompedor.
Sin duda, es un pack de baterías de calidad muy recomendable para todos los que tienen y usan cámaras de acción de DJI, tanto la 3, 4, 5 pro, como la 6. Sin duda, volvería a comprarlas. Gracias a este pack, nunca me he quedado sin baterías en mis viajes, siempre tengo 3 de repuesto y lo mejor de todo, es que puedo transportarlas y cargar 3 al mismo tiempo en un mismo cargador.

StefanoReviewed in Italy on January 15, 20265.0 out of 5 stars Ottimo kit: tre batterie e caricatore perfetti per Action 6 e 4
Ho testato questo kit K&F Concept composto da tre batterie da 2100 mAh e dalla custodia‑caricatore compatibile con DJI Osmo Action 6, Action 5 Pro, Action 4, Action 3 e Osmo 360, e posso confermare che funziona perfettamente sia con la DJI Osmo Action 6 sia con la DJI Osmo Action 4, che utilizzo regolarmente per le mie riprese.
Le batterie offrono prestazioni molto vicine a quelle originali DJI: la durata è stabile, l’erogazione è costante e non ho riscontrato problemi di compatibilità o messaggi di errore. Anche in sessioni prolungate e in condizioni di temperatura variabile non ho notato cali anomali. Per chi registra spesso in esterni, è un vantaggio concreto.
La custodia‑caricatore è uno dei punti più riusciti del kit. Funziona come caricatore rapido a tre slot, come contenitore protettivo e come organizer grazie ai due alloggiamenti per schede SD. Gli indicatori LED indipendenti permettono di controllare lo stato di ogni batteria in modo immediato. La ricarica tramite USB‑C è stabile e può essere alimentata anche da powerbank, rendendo il sistema molto pratico in viaggio.
La qualità costruttiva è elevata: la custodia è solida, compatta e ben assemblata, mentre le batterie si inseriscono con precisione e rimangono protette durante il trasporto. Il formato è ideale per chi vuole tenere tutto in ordine nello zaino senza aggiungere peso inutile.
Considerando la compatibilità reale con Action 6 e Action 4, la qualità dei materiali, la praticità della custodia e il prezzo più conveniente rispetto agli accessori originali, questo kit rappresenta una soluzione eccellente per chi utilizza le action cam DJI in modo intensivo.
Valutazione finale: 5 stelle.
