Frequently asked questions
Answers to the questions we get asked most often — about cells, technology, quality and ordering.
01What kind of batteries do you build?
We design and assemble lithium-ion batteries for drones (FPV, interceptor, ground and agricultural drones), EW systems, electric transport and power tools. We produce both serial runs and custom builds to the customer’s specification — over 500 product items.
02Do you make custom packs to my specification?
Yes. Tell us about the task — configuration, application, quantity — and we will engineer a pack to your requirements: custom shapes, capacities and dimensions. You can quickly pick a configuration in our online configurator.
03Which cells do you use?
Only A-grade 21700 cells from trusted manufacturers (e.g. INR21700-50TB). Before assembly every cell is sorted by internal resistance, voltage and capacity.
04How much current do your packs deliver?
Peak output of 200–400 A without voltage sag. High current delivery is critical for interceptor drones, where an instant burst of power matters.
05How are the cells connected?
By laser welding with copper busbars. This gives minimal internal resistance and a reliable joint that withstands high currents and vibration.
06How is quality controlled?
Control at every stage: cell sorting before assembly, joint inspection after welding, and the finished battery passes a load test in different temperature conditions.
07How do I place an order?
Contact us via the website form, Telegram, WhatsApp or by phone. Describe your task — we will suggest a solution and quote a price. Ready-made products are available in our online shop.
08Where is your production located?
Our production is based in Kyiv, Ukraine. Operating since 2020 — a full cycle in one place, from design to final testing.
