[ 04 reasons ] — why custom
Off-the-shelf packs are
a compromise.
We don't ship compromises.
Most eboards ship with the cheapest pack the OEM could source. We start with the cell, work out from there, and only stop when the geometry is right for your ride.
/01ESK-FACT
Hand-welded, never imported
Every nickel strip is laid down in our Vicenza lab. We pull random packs off the line and X-ray them. No subcontractors, no surprises.
→/02ESK-FACT
Telemetry baked in
Smart BMS over Bluetooth 5.0. Watch cell voltages, temperatures, and SoC live from your phone. Diagnose anything from anywhere.
→/03ESK-FACT
Built around your geometry
Bring us your deck dimensions. We CAD a pack that fits — slim, low-profile, weight-balanced. No more zip-tied bricks under your board.
→/04ESK-FACT
5-year battery warranty
We stand behind every cell. If a pack drops below 80% capacity in the first 5 years, we rebuild it. That's the deal.

Zero rebuilds we didn't honour.
Third pack from these guys. The first one is still on my commuter doing daily 15 km — 4 years in, 91% SoH.

I sent them my deck measurements on a Tuesday. Got the pack the following Wednesday. Fits like the deck was made for it.

Telemetry alone is worth the upgrade. Caught a sagging cell at 40 km and rolled home easy. Free rebuild under warranty.
