Seal 300A Opto ESC HV 14S ESC

Beautifully designed and manufactured, the new SEAL marine range of water-cooled brushless speed controllers by ZTW use new FETs that offer less resistance and less heat dissipation. ZTW has added additional water-pipes to increase the cooling area and so dissipate heat faster and with greater efficiency. The result enables higher power levels without fear of burning out the controller. Add to this a well-designed MCU with efficient code that makes for a faster sync and accurate control, and within this competitively priced package is a recipe for performance, reliability, and longevity.
