Frequently asked questions:

Q: Where do you ship from? How long does delivery take? Do I have to pay any customs taxes?

A: We ship worldwide from a warehouse located in Poland. Delivery time depends on your location and chosen shipping method.

Most customers receive their orders within 5-10 days.

You don’t have to pay any taxes if you live in one of the EU countries.

If you live in a non-EU country, please check your local customs regulations.

Q: Why so expensive?????!!!!!!!!!!!! Have you raised your prices???!!!!

AYes, unfortunately there are big problems with 18650 cells supply in 2022 due to the covid hustle and bustle. The cells have become 1.5 times more expensive compared to 2020, so we have to raise the price of the batteries. Another problem is the global shortage of semiconductors, which has doubled the cost of high-power transistors and microcontrollers, and that's why Rita and BMS prices also increased.
