Battery Engineering Partner
Custom Battery Packs for Robotics & Industrial Hardware
From prototype to production, we engineer lithium battery packs around your voltage, enclosure, current and environmental requirements.

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.
Engineering Examples
Real projects. Real constraints. Real solutions.

How We Work
From Sketch to Battery
A proven process for startups and engineering firms.
Tell Us What You're Building
Send voltage, energy, peak current, dimensions, temperature range, and quantity. Or just send your CAD drawing.
Feasibility Review
We review cell selection, series/parallel configuration, mechanical fit, BMS, thermal requirements, charging, and connectors.
Prototype Build
We build initial packs. Fast iterations — design changes measured in days, not weeks.
Test & Refine
We test under real conditions and modify the design until it meets spec.
Pilot Production
Start from 50 packs. UL, CE, UN38.3 and IEC 62133 certified as standard. ~10 week lead time.
Scale Without Switching
Go from prototype to production without changing suppliers. Same team, same quality, same relationship.
Free Tool
Estimate Your Battery's Thermal Behavior
Free preliminary simulation. Configure your pack and see thermal hotspots in real time.
Configure and run simulation
Every pack ships certified.
Lead time: ~10 weeks · MOQ: from 50 packs · Full certification documentation included
