Choose MiniStar 70C when its rated output, dimensions and price fit your aircraft's requirements. Choose MiniStar Pro 150C when the higher stated discharge rating and approximately 14g lower battery weight better suit your build. Neither version guarantees longer flight time or higher thrust without testing.
850mAh vs. 750mAh 4S Batteries
At the same nominal voltage, an 850mAh battery has approximately 13.3% more rated capacity than a 750mAh pack. This can provide additional energy, but a heavier battery may increase power consumption and affect handling. For a compact CineWhoop, compare actual battery mass and dimensions rather than choosing capacity alone.
XT30U Connector and 14AWG Power Leads
Each battery uses an XT30U power plug with 14AWG leads. XT30U belongs to the XT30 connector family, and a direct connection requires the correct mating connector, polarity and secure fit.
XT30 and XT60 are different connector formats. Use an appropriately rated adapter or connector conversion when necessary, and check that the complete power connection is suitable for the actual operating current. The battery's 70C rating does not override connector or ESC limits.
Standard 4S LiPo Charging: 16.8V Maximum
This is a standard 14.8V 4S LiPo battery, not a 15.2V 4S LiHV pack. Its maximum balanced charge voltage is 16.8V total, or 4.20V per cell. Do not use a 4.35V-per-cell LiHV charging program.
For routine charging, a balanced 1C rate of 0.85A per battery is preferred. The specified maximum is 5C, equivalent to 4.25A per battery, but this is not the everyday recommendation. Use a compatible 4S LiPo balance charger with the correct XT30 charging lead and JST-XH 5-pin balance connector.
Charge the two batteries separately unless using equipment specifically designed for safe multi-battery charging.
