I recently bought a DJI MINI 3 Pro, which had only 1 battery. I bought a set of 2 Coolshow batteries. They fit and work just like the oem battery, except they are a higher milliamp, so they provide longer flight time.

Battery life is just a good as a name brand battery. Fits my mini 3 perfectly.

Do not buy this battery if you are buying it for a Mini four pro. It does not work. The drone will not allow you to takeoff. It says non-DJI battery detected.

After testing the COOLSHOW replacement battery on my DJI Mini 4 Pro, I can confirm that it lives up to the performance claims and integrates seamlessly with the drone. Capacity and Flight Time – The 3850 mAh cells provide a solid boost over the stock capacity, delivering up to 37 minutes of maximum flight time under ideal conditions. In my real‑world tests—moderate wind, a mix of hovering and light maneuvering—I consistently recorded 32 to 35 minutes per charge, which is a noticeable improvement over the original battery’s typical 25‑minute endurance. Intelligent Compatibility – The battery’s built‑in smart circuitry communicates directly with the drone’s flight controller, preserving all of the Mini 4 series’ safety features. Voltage, temperature, and current are monitored in real time, and the battery reports its status accurately to the DJI app. I experienced no warning messages or abnormal shutdowns, and the low‑battery alerts behaved exactly as they do with OEM cells. Physical Fit – The form factor matches the original perfectly. The battery slides into the compartment without any fiddling, and the locking latch engages securely. There is no wobble or misalignment, and the weight is comparable to the factory unit, so handling and balance remain unchanged. Charging Experience – Using the standard DJI charger, the battery reaches full capacity in roughly 70 minutes. The internal temperature stays within safe limits throughout the charge cycle, and the charger recognizes the battery without any error codes. The battery charges the same as my OEM high capacity batteries on my fast charger too. Durability – The external housing is a robust polycarbonate shell that resists scratches and minor impacts. After several cycles of transport, including a few accidental bumps in my backpack, the battery shows no signs of damage or performance degradation. Value Proposition – Priced competitively for a single high‑capacity cell, the COOLSHOW battery offers a worthwhile upgrade for pilots who need extended flight windows without investing in multiple spare batteries. The combination of genuine capacity gain, reliable smart integration, and solid build quality makes it a practical addition to any Mini 4 series fleet. In summary, the COOLSHOW Mini 4 Pro Series Intelligent Flight Battery delivers the advertised 37‑minute maximum flight time, integrates flawlessly with DJI’s system, and holds up well under regular use. It is a reliable, cost‑effective alternative to the OEM battery for anyone looking to get more airtime out of their Mini 4 drone.

Review: COOLSHOW Mini 3 Pro/3 Series 3850mAh Intelligent Flight Battery The COOLSHOW 3850mAh battery is an aftermarket, high-capacity replacement designed for the DJI Mini 3 and Mini 3 Pro, essentially serving as a more budget-friendly version of the official DJI Intelligent Flight Battery Plus. For pilots looking to maximize air time without the OEM price tag, this battery offers a compelling but trade-off-heavy option. Extended Flight Performance The main appeal of this battery is its high capacity of 3850\text{mAh}, which is a significant upgrade from the standard Mini 3 battery's 2453\text{mAh}. The manufacturer claims a maximum flight time of 47 minutes, mirroring DJI's own Plus battery claims. In real-world user tests, the results are encouraging: one pilot recorded a solid 27 minutes of flight time while flying entirely in Sport Mode, which is the most power-demanding setting. Under more conservative conditions (Normal or Cine mode), users can reasonably expect flight times closer to the 35-40 minute range, providing a substantial increase in mission duration compared to the standard battery. Compatibility and Features The COOLSHOW battery is designed to fit and function seamlessly with the Mini 3/3 Pro drones and is generally compatible with original DJI charging hubs and cables. It features the essential safety protections common to intelligent batteries, including over-discharge, over-load, and short-circuit protection, offering a degree of peace of mind. Its lower price point compared to the official DJI Plus battery is a major advantage for budget-conscious flyers. The Critical Regulatory Trade-Off The single most important consideration for this battery is weight and regulation. The extra capacity means extra weight. The COOLSHOW battery has a reported weight of around 120\text{g}, which pushes the DJI Mini 3/Pro's total take-off weight to approximately 290\text{g}. Impact: This increase means the drone exceeds the critical 250\text{g} limit in many regions (including the US, Europe, and the UK). Action Required: Users in the US will be required to register the drone with the FAA, and pilots in other countries may face additional licensing or flight restrictions. If your primary reason for choosing a Mini drone was to stay under the 250\text{g} threshold, this battery defeats that purpose. Other Considerations A few users have reported initial inconsistencies, such as a temporary sudden voltage drop around the 20\% remaining battery level on the first few uses. While this issue reportedly resolved itself after a couple of charge cycles, it is a risk that requires early flight tests to be conducted cautiously. Furthermore, using a third-party battery like this could potentially void your DJI Care Refresh or standard warranty if a drone failure is attributed to the non-OEM power source. Final Recommendation The COOLSHOW 3850mAh battery is an excellent option for experienced pilots who prioritize maximum flight duration over regulatory convenience. It delivers on its promise of extended flight time and is significantly cheaper than the official alternative. However, if you need your drone to remain under the 250\text{g} limit for compliance purposes, or if you are uncomfortable with the potential warranty implications of using a third-party product, it is advisable to stick with the official DJI standard batteries. Just Like the OEM Factory Battery they are easy to install.
