ToolkitRC B50 Battery Warming Bag
Prepare compatible RC batteries for cool-weather sessions with the ToolkitRC B50 warming bag and temperature controller. The listed heating system provides up to 50W of heating power with an adjustable 25–55°C control range.
At your flying site, connect a compatible power source, select a temperature permitted by your battery manufacturer and monitor the warming process before use. The selectable range is a controller specification, not a recommendation to heat every battery to its maximum setting.
Heating Power, Not a 50W Battery Charger
The B50's 50W rating refers to its heater. Its separate USB Type-C output is listed at up to 20W for compatible devices. It is not described as a balance charger for RC flight packs, and the warming function does not charge the batteries inside the bag.
Key Features
- Adjustable temperature control: Listed range of 25–55°C; use only settings appropriate for the battery.
- Up to 50W heating: Actual performance depends on the power source, ambient conditions and contents.
- 6–28V DC input: Match the power source, polarity and required input connection before use.
- Up to 20W USB-C output: Device charging depends on compatible protocols and settings.
- 1.54-inch IPS display: Listed 240 × 240-pixel controller screen.

Compatibility and Power Setup
The selected option is B50 / USB Type-C. This label does not establish USB-C as the heater's power input: the written specifications identify DC input and USB-C output separately. Confirm the DC input connector, required source capacity, included leads and supported simultaneous functions before purchase.
Check the actual pack dimensions and manufacturer-approved warming conditions. This listing does not establish a universal battery chemistry, size or quantity allowance.
Perfect For
Experienced RC and FPV users seeking a controlled warming setup for batteries whose manufacturer permits pre-use warming. This is a warming accessory, not a battery or complete charging system.
What's Included
The listing describes a B50 warming bag and controller. Confirm the exact retail package, connection leads and accessories before ordering. Batteries, an external power source and an RC balance charger are not established as included.
Safe Use
- Follow both ToolkitRC instructions and the battery manufacturer's temperature limits.
- Never leave warming batteries unattended.
- Do not heat swollen, damaged, leaking or abnormal packs.
- Inspect the power connections and prevent short circuits.
- Keep the unit away from combustible materials and monitor the batteries during operation.
- Do not assume the bag is fireproof or that warming permits charging or flight outside the battery's approved operating limits.
- Do not charge batteries inside the warming bag unless the relevant manufacturers explicitly permit that setup.
