High-rate Li-ion packs combine proven cylindrical cells with custom engineering: strong discharge, long cycle life and a mature supply chain for products that must last. ZERA POWER builds packs around branded cells, including Samsung SDI, and validates discharge, temperature and cycle behaviour before production. The result is a dependable pack for e-bikes, storage systems and drones that need power without compromise.

Frequently Asked Questions
Which cell models do you use?
We work with branded cylindrical cells including Samsung SDI 26JM, 30Q, 35E, 50E and 50S. The right model depends on your discharge, capacity and cycle-life priorities, and we recommend the best fit after reviewing your load profile.
Do you supply cells on their own?
Our focus is finished packs and solutions, not bare-cell retail. If you need cells for a pack project, tell us the model and quantity and we will advise what we can support.
Can you match an existing pack I already use?
Yes, in many cases. Share the existing pack’s voltage, capacity, dimensions, connector and discharge requirements, and we will design a compatible replacement or upgrade.
What information do you need for a quote?
Voltage, capacity, peak and continuous current, size limits, connector type, operating temperature and estimated quantity are enough for a first proposal. A sample or datasheet of your device helps us refine it.
