Stop Guessing, Start Balancing

A poorly charged LiPo battery doesn't just reduce your runtime; it can permanently damage your gear. For RC enthusiasts, battery health is paramount. The Hot RC B3 20W Compact Charger takes the guesswork out of battery maintenance. By utilizing dedicated, separated balance ports for 2S and 3S battery packs, it ensures every individual cell is charged safely and evenly to its maximum capacity.

Maximum Power in a Minimal Footprint

Don't let the small size fool you. Weighing in at just 162g, this exquisite little unit pushes out a solid 20W of maximum power with a 1.6A charge current. It’s light enough to toss into your pit bag without adding bulk, making it the perfect companion for track days, field flights, or weekend bashing sessions.

Plug-and-Play Simplicity with Global AC Input

Forget about bulky external power supplies. The B3 Compact Charger features a built-in 100V-240V AC input, meaning you can plug it straight into the wall right out of the box. The intuitive three-bicolor LED display gives you instant, real-time feedback: red means it's actively charging, and green tells you your pack is fully primed and ready for action.
