The 11.1V 4200mAh BONKA LiPo Battery Pack is a lighter-capacity variant, delivering 4200mAh of capacity at 11.1V nominal from three lithium polymer cells connected in series, making it a popular choice for F450 quadcopter drone for a practical balance between flight time. The lighter weight of the 4200mAh pack compared to the 5200mAh results in a lower for the same drone airframe, which translates directly to more agile throttle response, quicker acceleration, and a livelier flight feel that many prefer over the longer-but-heavier flight profile of the higher-capacity pack. The 3s lipo battery pack connects via the XT60 discharge plug to the drone’s power distribution board or ESC battery input lead.
The 11.1v 4200mah lipo battery is rated at 35C continuous discharge, which means it can safely deliver 147A continuously (35 multiplied by 4.2Ah) — significantly more than the approximately 40 to 48A that a standard F450 quadcopter with four 2212 920KV motors draws at full throttle, giving the 3s lipo battery for drone ample current headroom without thermal stress on the cells during normal flight. The 70C burst rating allows approximately 294A for brief peak demand intervals during rapid throttle-up movements, accommodating the sudden current spikes that occur when climbing from hover to full throttle.
The rc drone battery with a JST-XH balance plug alongside the XT60 discharge lead, allowing the per-cell voltage of each of the three cells to be equalized through a balance charger during every charging cycle for safe and long-lasting cell health. This drone battery 4200mah BONKA is perfect for quadcopter rc drone in India.
