Quick answer
Choose a Shimano STEPS off-bike charging adapter by the battery model and approved charger connection, not just the bike brand. SM-BTE60-style and SM-BTE80-style connections serve different battery families. VELYN lists separate ALLTOO compatible adapters for each format; compare the exact model and connector before ordering.
SM-BTE80 charger compatibility depends on the battery
BT-E8035, BT-E8035-L and BT-E8036: use an EC-E6000, EC-E6002 or EC-E8004 only where approved for the exact battery. BT-EN805, BT-EN805-L and BT-EN806: use EC-E6002 or EC-E8004; do not use EC-E6000 with this group. The adapter does not make an unsupported battery/charger combination compatible. Confirm the full battery and charger model numbers and the connector before ordering.
What is an off-bike charging adapter?
An adapter connects an existing compatible charger to a battery removed from the bicycle. It is a connection accessory, not a replacement battery or a complete charger. It does not make an unrelated charger suitable for an e-bike battery.
Start with the model printed on the battery, then identify the charger. A motor name or the word STEPS is not enough to select an adapter. Check the battery and charger documentation together, including model suffixes and regional differences.
SM-BTE60-style vs SM-BTE80-style connections
| Battery family | Connection to investigate | VELYN option |
|---|---|---|
| BT-E6000, BT-E6001, BT-E6010 | SM-BTE60-style; confirm charger pairing | ALLTOO SM-BTE60-compatible adapter |
| BT-E8035, BT-E8035-L, BT-E8036 | SM-BTE80-style; confirm charger pairing | ALLTOO SM-BTE80-compatible adapter |
| Other models or suffixes | Consult the exact battery and charger manual | Check the listing and ask VELYN with the full model number |
Shimano illustrates these adapter families in its STEPS battery and charger manual. This reference describes Shimano equipment; it is not certification of the ALLTOO accessories sold here.
Four checks before ordering
- Read the full battery model from its label, including suffixes.
- Record the charger model and check the permitted battery and charger combination.
- Compare the connector and contact arrangement with your existing equipment.
- Confirm you need an off-bike adapter rather than a charger or an on-bike cable.
Choose by the confirmed connection
For a confirmed SM-BTE60-style connection, review the SM-BTE60-compatible adapter listing. For a confirmed SM-BTE80-style connection, review the SM-BTE80-compatible adapter listing. Current listings describe the intended battery and charger combinations. Ask for model confirmation if any part of your setup differs.
Frequently asked questions
Are SM-BTE60 and SM-BTE80 interchangeable?
Treat them as different formats. A matching brand name does not establish electrical or mechanical compatibility.
Does the adapter charge a battery on its own?
No. You need a compatible charger and must follow the battery and charger instructions.
Can I select it by the motor model?
Use the battery and charger labels instead. Bikes with a similar motor can have different charging connections.
These are aftermarket compatible accessories, not original Shimano products. Compatibility references do not indicate authorization, certification or endorsement.
