8233112655?profile=RESIZE_710x

We built BatMon for making smart batteries. BatMon can now talk with Ardupilot, Pixhawk, and ROS and enables safe and robust operation of robot using smart batteries. But there is a missing piece, a smart charger that can safely charge batteries with a peace of mind for customers.

So, we are building exactly that, and a lot more, to future proof your workflow as they scale. Below is a sneak peek of the most foolproof futureproof smart charger we know of: BatCha

BatCha features

  • Opensource Firmware
  • 2-12S LiPo Charge
