Frequently Asked Questions

We aim to respond to enquiries within 24 hours during business hours. Once your quote is accepted and payment is processed, custom batteries are typically dispatched within 2–3 working days, subject to stock availability and order size.

If additional production time is required, a team member will promptly update you with an estimated delivery timeframe.

Voltage must match your device’s requirements, while capacity (measured in mAh) affects runtime. If you’re unsure, refer to your device’s specifications or reach out to us for guidance.

NiMH cells have fixed sizes and weights, but we offer a variety of configurations to help fit your specific application. If you have size constraints, let us know your requirements, and we’ll work to find the best possible solution. While we may not always achieve exact dimensions, we will do our best to provide a suitable alternative.

We provide a variety of connectors to match different NiMH battery sizes and applications:

  • For smaller packs: JR Universal, Mini Tamiya, SM2P, Spektrum, XT30
  • For medium packs: Deans, EC3, EC5, Gold Connectors, Tamiya, Traxxas, XT30, XT60, XT90, XT150
  • For large-scale packs: AS150, QS8, XT150

If you need a connector not listed, contact our team, and we’ll do our best to accommodate your request.

Yes, modifications can be made if production hasn’t started. Please contact us as soon as possible to request changes.

Yes, our custom NiMH batteries include a 12-month standard warranty covering manufacturing defects. However, as each battery is made to order, we cannot accept returns unless there is a fault—for example, if the battery is no longer needed or unsuitable for your application.

Customers are responsible for ensuring the battery specifications meet their needs before production begins. Once assembly starts, orders cannot be cancelled.

Pricing depends on factors such as voltage, capacity, and any additional features. We’ll provide a customised quote after assessing your specifications.

Unfortunately, we cannot ship batteries outside the UK. If international delivery is needed, customers must arrange their own forwarding service.
