Custom Battery Manufacturer
EI Sales connects OEMs to trusted custom battery manufacturers like Jauch, coordinating engineered solutions built to meet specific electrical, mechanical, and compliance requirements. We focus on high-reliability packs, short lead times, and design-stage support that helps teams move efficiently from prototype to production. Our team works closely on battery configurations built to match the specific needs of wearable devices, surgical tools, and rugged control systems.
Battery Types We Offer
EI Sales helps OEMs specify the right cell chemistry, pack design, and performance features for their application. Our team works directly with engineers to match battery solutions to size, voltage, and safety requirements across use cases. We offer individual primary and secondary cells of the following chemistries:
- Lithium ion batteries
- Lithium polymer batteries
- Lithium Thionyl Chloride Batteries
- Lithium Coin Cells
- Lithium Batteries cylindrical
- Lithium Iron Phosphate Batteries
- Sodium Ion Batteries
- NiMH batteries
Custom Lithium-Ion Packs
Lithium-ion packs offer high energy density in a compact footprint. Ideal for portable medical equipment, industrial handhelds, and rugged electronics that require extended runtime and smart control features.
Custom Lithium Polymer Packs
For applications that require lightweight and slim packaging, lithium polymer (Li-Po) batteries support flexible design. Common in wearables, wireless sensors, and space-constrained devices.
Nickel-Metal Hydride (NiMH)
NiMH batteries provide a rechargeable alternative for mid-power devices that don't require lithium chemistry. Often used in field service tools, test equipment, and consumer-grade electronics.
Coin & Button Cells
Compact and reliable, coin and button cells are widely used in memory retention, RTCs, and low-power embedded functions.
Primary Lithium (Li-SOCl₂, Li-MnO₂)
These high-capacity cells support applications requiring long shelf life and low discharge rates, such as remote sensing, alarm systems, and asset tracking.
Rechargeable & Non-Rechargeable
We help match the appropriate cell type to the product life cycle, usage pattern, and charging environment, selecting between rechargeable and primary options based on application needs.
Smart Battery Packs (SMBus, I²C)
Jauch's smart pack options feature built-in communication protocols for fuel gauging, thermal protection, and system integration.
Custom Voltage & Size Options
We coordinate pack customization across a range of configurations, adjusting voltage, current, size, and compliance features to match the application.

Get the Right Battery Fas
Speed matters during design cycles and early-stage development. EI Sales helps OEMs move quickly by working directly with manufacturers who build to spec and ship on short timelines. We reduce sourcing delays through early involvement, clear documentation, and alignment on safety, certification, and fit requirements.
For urgent needs, we coordinate with partners offering prototyping services and in-house testing. Projects stay on track with fewer revisions and faster approvals.
Built for Demanding OEM Use
OEMs rely on EI Sales to support battery designs that must meet strict performance, safety, and regulatory standards. We align manufacturing resources to deliver rugged, traceable packs that support complex build criteria.
Battery packs are available with integrated safety electronics, communication interfaces, and temperature protection. We assist during design reviews, compliance checks, and system-level validation to help teams avoid costly redesigns later.
