I have just purchased your Nexto di NPS-10. You mention in your NPS-10 users manual NPS-10_EN_V1.1_.pdf, that:
"The rechargeable battery can be recharged 400 times. If the battery operation time gets shorter, it may be time to replace the battery. Consult your authorized NEXTODI dealer to replace the internal battery"
400x does not seem like a lot of charges for a unit that is meant to be able to last longer with replaceable ssd/hd's. I searched your site to purchase an extra battery but cannot find anything for the NPS-10. Does this mean that I have to send the unit in to get the battery replaced when the useful life gets shorter?
