Very interesting design. how is it holding up? seems like the weight distribution in how you split and located the battery packs is a big plus. nice work!
Hi,
some advantages - but one disadvantage is 2x battery handling 2x BMS cable.
Otherwise the E Foil was built quickly and cheaply.
The VESC housing made of stainless steel (100% waterproof) has good heat transfer into the water.
The telemetry and the driving signal come to the controller via the plastic window (unbreakable Lexan Sheet) at the rear.
