I’m configuring my first e-board and need some advice for my setup. Ordered is a Alien 5065 220kv sensored motor and a VESC 4.12. The gearing is not yet fixed, I’ll start with a 16/48 with a cheap China motor mount on 80mm wheels, just for the first tests.
My biggest question is about the batteries. I planned to use two 4S 5Ah with 30C in series for 8S voltage. The motor is rated with 50A max, so the XT60 connectors and 2,5mm² cables (slightly larger than AWS12) should be fine. Am I right and is this setup durable?
I also read about that the VESC has a option to shut down the board on a specific voltage, so the batteries do not get deeply discharged. Is this right and enough to protect the batteries? For now I do not have planned to install a BMS, I want to charge the batteries with a standard 4S charger and a BMS for > 50A is quite too expensive for now.
My aim is to have a good balance between durability, the price point, torque and speed. to get started. I chose the 50mm motor for the option to easily upgrade to dual motor. But for now my budget says getting the board to work is the first priority, improvements will have to wait.
Thanks a lot for your support!
