Donut Goes Pack-Level with Verge TS Pro Charging Test

After a run of cell-level tests with VTT, the latest video finally shows what everyone’s been waiting for, the battery in an actual bike.
A Verge TS Pro test mule, plugged into a public fast charger, running Donut’s solid-state pack in the real world. No lab coats this time. Just a bike, a cable, and a stopwatch.

Key Takeaways from the Pack-Level Test
First proper pack test. Up to now, everything’s been cell-level. This is the tech working inside a complete battery pack on a motorcycle.
Charging starts low and hits hard. The bike plugs in at around 9–10% state of charge and immediately pulls serious power.
100 kW+ charging on a bike. The pack sustains 100+ kW, which is big numbers for a motorcycle platform.
~5C pack-level charge rate. That translates to roughly 10–80% in about 12 minutes, well beyond typical e-moto charging speeds. It’s in the same ballpark as the LS-218 claims.
Air-cooled setup. No liquid cooling system, just air handling those charge rates. It supports Donut’s wider claims around thermal stability, but doesn’t prove them outright.
Not quite CES numbers. Peak charging sits around 100 kW, not the ~200 kW originally mentioned — likely down to charger limits, bike integration, or the test setup itself.
The BCB Take
This is the first time Donut’s story starts to feel like it’s touching the road. Up to now, everything’s been best-case lab work on a single cell. That argument gets weaker once you bolt the thing into a bike and plug it into public infrastructure.
A 100 kW, air-cooled motorcycle pack pulling a ~12-minute charge is properly interesting. Not just for what it could mean at scale, but from an engineering standpoint too. Because right now, no one really knows what’s inside these packs. There’s a lot of noise out there, some informed, some less so, but not much that’s actually been confirmed.
That said, the big ones are still unanswered:
Energy density (400 Wh/kg)
Cycle life (100,000 cycles)
And it’s worth keeping in mind that the numbers this week are strong, but they’re not quite the headline CES figures that we saw earlier this year. But, this is the first time we’ve seen the tech outside the lab and on an iron horse, so if anything, we’re even more focused on what comes next.
Ride safe, folks.
