Registering activates the warranty on your pack. You will need the model and serial number printed on the battery itself, and a photo of your invoice.

1 Who you are
2 Which battery

The category, model and serial number are printed on a label on the pack itself.

3 Where it is installed
4 Proof of purchase

A photo of the invoice is enough. This is what dates your warranty, so it is required. JPG, PNG, WEBP or PDF, up to 5 MB.
