The "Ro-Heat" heating bag is designed for preheating LiPo batteries commonly used in model building. Made from flame-retardant material, it features a Velcro fastener. LiPo batteries that drop below room temperature lose significant capacity and performance and can, in extreme cases, be permanently damaged. This is why preheating "undercooled" LiPo batteries is especially recommended in cold weather.
With the Robbe "Ro-Heat" heating bag, you can easily and conveniently warm up the LiPo battery. The temperature can be preset to 40°C, 30°C, or 20°C using a button. On the inside of the heating bag, a heater is integrated on one side. It is recommended to occasionally rotate the battery to ensure even warming.
The heating bag can be powered by a sufficiently powerful 3S LiPo battery or a 12V/DC power source. It can also be used with a 12V car battery, although continuous operation is not allowed in this configuration (a fully charged car battery has a voltage well above 12V).
Note: there is no undervoltage shutoff! If the device is accidentally left running with a battery as the power source, it may be fully discharged, potentially causing damage.
Operation: - Press the button for a long time > Heating is activated > 40°C will appear on the display.
- Press the button briefly again, the target temperature of 30°C will be set.
- Press the button briefly again, the target temperature of 20°C will be set.
- Press the button briefly again, the target temperature will return to 40°C.
- Press and hold the button > Device is turned off.
We recommend operating it only under supervision!
