| Bike | Focus Jam2 (Shimano E8000) |
|---|---|
| Drive system | Shimano STEPS E8000 / E7000 / E6100 |
| Battery that fits | Shimano STEPS BT-E8020 (504 Wh, 36 V integrated) |
| Charge port | Higo / Julet charge and signal connector |
| Charger | Shimano EC-E8004 / EC-E6002 charger |
The Focus Jam2 (Shimano E8000) runs the Shimano STEPS E8000 / E7000 / E6100, a Shimano drive whose battery is proprietary to the system, so the replacement pack is one of its own, most often the Shimano STEPS BT-E8020 (504 Wh, 36 V integrated), charged through the Higo / Julet charge and signal connector.
A newer STEPS pack only charges on the EC-E6002 or EC-E8004; an old EC-E6000 with the same connector no longer charges current BT-E8010 units, so a look-alike old charger can silently fail.
