Robustness and Repairability
We believe a charger should last for a lifetime, and not be e-waste after a little time. BatCha is housed in an extruded aluminum case. Every component has been chosen, within reason, for robustness and long life. While BatCha is not unbreakable (it’ll most likely blend if you try hard), every module is designed to be replaceable. We ensure that any of the replacement part cost below $100.
Customizability and Open Source Firmware
BatCha is customizable charger for most of your charging needs. BatCha’s firmware is open source enabling users to build communication protocol to talk to most smart batteries. Custom connector interfaces may be built such as those shown below:
*Optional module: There are thousands of dumb batteries currently used by hobbyist. BatCha provides an elegant interface to quickly set charging parameters, and charge. Hobbyist and engineers often have to juggle between many different types of batteries. BatCha remembers previous battery settings and automatically present the user with most likely charge settings. BatCha UI is designed to get from plug-in to starting-charge in less than 4 seconds, even for a dumb battery.
BatCha would be launched on a crowdfunding campaign soon. If you are interested in supporting the campaign, please sign up below. If you are interested in being a contributor for the firmware and charger design, please send us an email: firstname.lastname@example.org.
