BMSes shipping now!
Due to request from the community, the BMS is now compatible with 18S, 19S batteries along with 20S batteries.
What is the Fungineers Funwheel BMS:
The perfect BMS doesn't exis...well, we made the perfect BMS. After the community complained about the extortionate prices of smart BMSes, and the unavailability and uncertain nature of dumb BMSes, we took it as a sign from God himself, that we ought to solve this problem, so, without further ado, and more than a year in development and testing, we partnered with one of the leading battery and BMS makers, and produced a professional industry grade BMS, because there is no compromise when it comes to battery safety.
The BMS comes with a Bluetooth module with a dedicated app to monitor individual cell voltages (Android and iPhone).
The BMS has no on/off switch and no connection to the VESC or any switch. It turns on automatically once a charger is connected, and remains on for monitoring and balancing for upto 10 hours after the charger is disconnected.
The connectors are:
XT30 connectors coming from the charge port, and going to the battery.
JST ph2.0mm 10 pin and 11 pin connectors for the balance wires (male connectors with long wires for soldering to the battery will be provided for battery builders)
If you do not wish to build the battery yourself, please ask your favorite battery builders to contact us and use the BMS in your battery builds (chances are they already are using them).
