Ethix Heated LiPo Bag is a battery bag designed by the well-known pilot Mr. Steele for optimal performance in cold weather. Cold batteries have a higher internal resistance and experience a faster drop in voltage and capacity under load, which is why they need to be preheated before use in winter. This bag ensures that your batteries maintain the ideal temperature for flight.
The heating is powered by an integrated regulator that can be connected to a 3–6S LiPo battery and features automatic low-voltage cutoff (3.5V per cell). The regulator heats the batteries to a target temperature of 50 °C and also allows for charging a phone or camera via the USB 5V/2A output.
The bag itself is thermally insulated and closes with a zipper. On the outside, there is a practical pocket for storing a phone or accessories. Inside, it can neatly hold up to 30 pieces of 1300mAh 4S batteries or 20 pieces of 1300mAh 6S batteries.
If necessary, it is possible to perform a voltage measurement recalibration for more accurate value readings.
