Sky Power (US)

Bring Heart To Power

Your Battery Problem

That's usually where we come in.

"The enclosure is already designed."

We engineer the pack around it.

"We only need 50–500 units."

That's exactly the kind of run we support.

"The robot needs high peak current."

We select the right cells and pack architecture.

"It has to operate in extreme temperatures."

We evaluate cell, pack and thermal behavior down to -40°C.

"We're not battery engineers."

Good. You don't need to become one.

Why Sky Power (US)

Built for Engineers Who Can't Afford to Wait

📦

Small MOQ

From 50 packs for development builds. Scale to production without changing suppliers.

Fast Re-Design

Design iterations in days. Our engineers turn feedback into updated specs fast.

🌡️

Built for Difficult Environments

Extreme temperatures (-40°C to +85°C), vibration, high C-rate, constrained enclosures. Validated, not estimated.

🔋

High C-Rate

Up to 5C continuous discharge. Engineered for robotics, UAVs, and high-draw devices.

🔬

Thermal Expertise

In-house thermal simulation and validation. Every pack ships with a certified thermal profile.

📋

Certified

UL, CE, UN38.3, IEC 62133 certified as standard. Full documentation for your compliance team.

Too Small for a Giant Battery Supplier?

That's where we fit. We support custom battery projects from first prototype through scaling to production. You don't need to be a Fortune 500 company to get serious battery engineering.

Prototype → 50 packs → 500 → Production

Scale to production without changing your battery supplier.

How We Work

From Sketch to Battery

A proven process for startups and engineering firms.

01

Tell Us What You're Building

Send voltage, energy, peak current, dimensions, temperature range, and quantity. Or just send your CAD drawing.

02

Feasibility Review

We review cell selection, series/parallel configuration, mechanical fit, BMS, thermal requirements, charging, and connectors.

03

Prototype Build

We build initial packs. Fast iterations — design changes measured in days, not weeks.

04

Test & Refine

We test under real conditions and modify the design until it meets spec.

05

Pilot Production

Start from 50 packs. UL, CE, UN38.3 and IEC 62133 certified as standard. ~10 week lead time.

06

Scale Without Switching

Go from prototype to production without changing suppliers. Same team, same quality, same relationship.
