Connect the battery to a compatible 2S LiPo charger using the JST or XT60 connector and charge at 1C rate (0.85A) until the charger indicates full charge at 8.4V total or 4.2V per cell. Never exceed 1.5C charging rate as this may cause overheating and reduce battery lifespan. After each flight or use session, allow the battery to cool for 10-15 minutes before charging, and always balance-charge using the balance connector to ensure even cell voltage distribution.\u003c\/p\u003e\n\n\u003cp\u003eFor storage longer than two weeks, discharge the battery to storage voltage (3.85V per cell or 7.7V total) using a compatible charger with storage mode function. Store in a cool, dry location away from direct sunlight and extreme temperatures, ideally between 15-25 degrees Celsius. Never store a fully charged battery for extended periods as this accelerates capacity loss. Before each use, verify both cells read 3.7-3.85V using a battery checker to confirm safe operating condition. Immediately remove the battery from service if it swells, shows reduced capacity, fails to hold charge, or develops a burnt smell, as these indicate internal damage requiring safe disposal.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the difference between 25C and 30C discharge rating?\u003c\/summary\u003e\n\u003cp\u003eThe discharge rating indicates maximum continuous current capacity. A 30C rating on 850mAh means 25.5A maximum current (850mAh x 30 = 25,500mA), while 25C would limit to 21.25A. Higher C-ratings enable faster acceleration and more aggressive flight maneuvers without voltage sag, but generate more heat. The 30C rating makes this battery suitable for racing drones and high-performance RC aircraft where sustained high current is essential.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eHow long does this battery last per charge?\u003c\/summary\u003e\n\u003cp\u003eFlight time depends on your RC platform's weight and throttle usage. Typically, this 850mAh 2S battery provides 6-12 minutes of flight time on quadcopters, 8-15 minutes on RC aircraft, and 10-20 minutes on RC cars depending on load and driving style. Aggressive flying with continuous full throttle reduces flight time to the lower end, while smooth, controlled flying extends duration toward the upper range.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eCan I use this battery with a 3S charger?\u003c\/summary\u003e\n\u003cp\u003eNo, never attempt to charge a 2S battery with a 3S charger. Doing so will overcharge the battery to dangerous voltage levels, causing internal damage, fire risk, and potential injury. Always use a charger specifically configured for 2S LiPo batteries. Verify the charger display shows 2S mode and reads approximately 8.4V when fully charged before connecting your battery.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eWhy does my battery swell after use?\u003c\/summary\u003e\n\u003cp\u003eSwelling indicates gas buildup inside the battery cells due to overcharging, over-discharging below 3.0V per cell, physical damage, or internal short circuits. Swollen batteries are unsafe and should be removed from service immediately. Prevent swelling by charging at appropriate rates, never discharging below 3.0V per cell, storing at 3.85V per cell, and avoiding physical damage. If swelling occurs, safely dispose of the battery at an electronics recycling facility.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eWhen will I receive my order?\u003c\/summary\u003e\n\u003cp\u003eOrders are dispatched within 1-5 business days from our Bengaluru warehouse.
