Product overview
The KlesMan KLSM3500 is a lithium polymer battery pack intended to supply power to FPV racing drones and other UAV applications. Its 6S configuration operates at a stated 22.2V, with a 420g mass and dimensions of 135*43*22mm defining the battery space and weight allocation needed for integration. The product-description capacity is 3300mAh, while an additional specification states 3500mAh. This capacity discrepancy is material to procurement. The supplied product is a battery pack; standard packaging contains 20pcs/carton, and the warranty is one year.
Charging requires a LiPo-compatible balance charger, with charging limited to 4.2V per cell and discharge restricted to no lower than 3.2V per cell. Charging and storage require a LiPo-safe bag on a concrete surface away from flammable materials. Use must stop if the pack expands or its temperature exceeds 70° Celsius / 160° Fahrenheit. The terminals must be protected against short circuits. Adult supervision is required during use, and storage must prevent access by children or infants; improper handling can cause fire or explosion.
