Description
Description
If you already own a Duotone Foil Assist setup and need a replacement or extra single battery, this is the correct part. The Duotone Foil Assist Battery 7A (1Pcs) is one original 7Ah high-voltage battery built for the 2026 Duotone Foil Assist battery ecosystem.
The important point before you buy is simple: this is one battery only. The Foil Assist system needs two batteries connected at the same time to operate, so this product is best suited to riders replacing one damaged battery, completing an existing pair, or keeping a spare ready for travel and backup.
Where This Sits in the Range
This sits firmly in the spares and replacement side of the Duotone electric range rather than the “start here” part of the system.
- Choose this if you need one replacement battery.
- Choose the Duotone Foil Assist Battery 7A Set (2Pcs) if you need a complete working pair.
- Choose the Duotone Foil Assist Set AL if you are building a system from scratch.
- Choose the Duotone eHarness Set if you need the wearable harness and battery box rather than the battery itself.
Why Choose This Battery?
- Genuine Duotone replacement part for the current Foil Assist battery platform.
- Ideal if one battery has been lost or damaged and you do not want to buy a full pair again.
- Useful as part of a spare battery rotation for longer days, travel or shared use.
- Compact travel-friendly format with each battery sitting just under the common 160Wh airline threshold.
- Simple charge-status display thanks to the built-in button and LED indicators.

Is one battery enough to run the Duotone Foil Assist?
No. You need two batteries connected at the same time for the Foil Assist system to operate. This product is a single replacement battery, not a complete working set.
Who should buy this instead of the 2-piece battery set?
Buy this single battery if you are replacing one damaged or missing battery, or if you already have an existing battery setup and only need one extra. If you need a full usable pair, the 2-piece set is the better buy.
Can I travel by air with this battery?
Each battery is rated at 159.6Wh, which sits just under the usual 160Wh airline threshold. That said, airline rules can vary, so you should always check the latest policy and get approval before travelling.
Is this compatible with Duotone Cruise as well as Foil Assist?
Yes. This battery format sits within Duotone’s electric foil ecosystem and is used across current Foil Assist and Cruise-related setups using the same 7A battery platform.
Anything else I should know before ordering?
Yes — this is a lithium battery product, so shipping can sometimes take longer and delivery options may be more limited than for standard accessories. It also makes sense to store batteries carefully and follow Duotone’s charging and storage guidance.
