The 'MINI MONSTER'' series of controllers.
6-FET circuit boards with IRB4110 brawn and '116' chip brains promise to do a big job in a small package. Yes, the wait is (nearly) over for compact, multi-kW, instant-throttle, high-voltage capable, feature rich, programmable and affordable ebike power control
...Well, alright, I have 9 cute little yellow circuit boards in hand and am waiting on a box of power parts that seems to be afraid to land...
However, the mission is clear: smaller, smarter and sexier controllers for all (with discount prices to members)!
Stator has received one of my 100V boards, is installing his own 4110 FETs, and will be testing the limits soon.
I will be building and testing as soon as my own 4110s land and then be offering various voltage/current/feature configurations for sale (perhaps including some DIY kits). The controllers will be built with tinned 10 gauge cables, precise shunts, Anderson power connectors, Crystalyte style connectors, and sealed on/off buttons (and debt to Method's procurement services!). Prices will depend on the final cost of (my own) labor.
- Specifications so far:
- Size: 100mm x 65mm x 35mm (4" x 2.55" x 1.25") - a bit longer than a credit card.
Voltages: up to 100V
Current handling: up to at least 60A continuous at 50V, yet to be determined at higher voltages (probably less)
Available Features (all programmable):
- Low Voltage cutoff and tolerance (LVC)
Current limiting (battery and phase)
3 speed selection (timing advance?)
Anti-theft (Motor lock trigger)
This series of controllers were inspired by Method's original 6 FET, 60A modified, Infineon unit as well as the pioneering work and spirit of so many other ES members. The '116' chip based boards offer much faster throttle response and greater programmability than the previously used Infineon chip based models and represent great value in capabilities and features. After following months of the exciting developments with the monster, 18-FET controllers and waiting for someone to turn their attention to the 6-FET baby of the family, I thought it best I just source the boards myself and get the party started.
