Jeff Freisen steps back from FOCBOX Unity to help build a better ESC from the ground up: Stormcore

After the recent news of Enertion going into liquidation, many electric skateboard builders worldwide were looking for alternatives to replace the popular FOCBOX Unity. Jeff Freisen who is the original engineer behind the FOCBOX Unity revealed that he has silently been working together with LaCroix and Charles Allix on a brand new ESC for the past seven months.

ESC stands for electric speed controller. Which is the essential part of an electric skateboard controlling the speed, breaking and reversing of your motors. Further developments in ESC technology help electric skateboards ride more efficient, handle higher power and reduce thermal throttle.

The new ESC is called Stormcore and will be available in three models: 100D, 100S and 60D (100V dual, 100V single and 60V dual). Stormcore promises improvements on every level over the original Unity. Hoping to make this a reliable next generation ESC for electric skateboards.

But even though Jeff had a lot of experience developing the Unity, working on Stormcore wasn’t easy. Jeff had to invest his personal savings as there was no company supporting him in the early stages: “I worked on this unpaid for about four and a half months. I didn’t have any other employment during this time and my savings took a huge hit, I had to even reach out to my parents to help support me toward the end.”

Design from scratch.

Stormcore will not have any relation to Jeff’s previous ESC Unity. He states every aspect of this controller is different: “Wanting a clean break from Enertion, I scrapped the design files of the unity. I started from scratch, on a fresh file after resigning, at the advisement of some legal council and began the creation of a new dual controller. I felt I had made some mistakes with my first controller and knew I could do better.”

Stormcore is still in development and first results look very promising. Stormcore will release via LaCroix, who are a established Canada-based brand with years of experience in parts and all-terrain electric skateboards. The new ESC is already welcomed with open arms by different vendors, with Bioboards promising it will have Stormcore in their next Thorium model.

Don’t know If these are his words…Or the written words of a journalist…
But a développer who’s complaining before the end-product is finished…
Doesn’t seems he’s still passionate but more likely on a financial quest…
Wich makes me curious of the quality of his product to be…
