Welcome to my blog about opensource high power BLDC motor drivers. Here you can find all information about my controllers in one place.

Having trouble with your homemade BESC? Head over to FAQ for troubleshooting tips.

Currently there are two BESC models and on in development. They are similar with some differences in their specs.

BESC-G1 specs

• 135V absolute max supply voltage (30S lithium battery capable)
• 200A max phase current
• Phase current sensors (hall)
• 12x IPB044N15N5 150V MOSFET

BESC-G2 specs

• 100V max supply voltage (24S lithium battery capable)
• 400A max phase current
• Low side shunt current sensors
• 24x IRF135B203 135V MOSFET

BESC-G3 specs (in development)

• 100V max supply voltage (24S lithium battery capable)
• 600A max phase current
• Phase current sensors (hall)
• 36x IRF135B203 135V MOSFET
