Frequently asked questions

Energy Access products are designed and assembled in the United States.

We maintain in-house engineering, prototyping, manufacturing, and quality control to ensure consistency, supply chain visibility, and the ability to respond quickly to custom requirements.

Energy Access was founded in 1998 and has been designing custom battery charging and power management solutions for nearly three decades.

We've delivered products to medical device manufacturers, military contractors, industrial OEMs, robotics companies, and consumer electronics brands worldwide.

Standard products carry a 1-year limited warranty against manufacturing defects.

Extended warranty options are available for custom and OEM volume purchases. Detailed warranty terms are documented in our standard terms and conditions and can be customized for negotiated supply agreements.

All Energy Access products include access to our engineering team for integration support, troubleshooting, and application guidance.

We provide complete product documentation, spec sheets, and CAD files on request. For custom designs, we provide test reports and validation data alongside the product.

Yes — selected accessories (line cords, power supplies, vehicle adapters) are available through DigiKey for self-serve ordering.

For chargers, BMS, and custom solutions, we recommend direct purchase via our quote process to ensure you get the right configuration, pricing tier, and engineering support.

Standard timelines:

• In-stock items: ship in 1-3 business days
• Standard configurations not in stock: 4-6 weeks
• Customized standard products: 6-10 weeks from order
• Custom designs: vary by complexity (see custom design lead time FAQ)

Rush options available — contact sales.

Depends on the product:

• Off-the-shelf products: typically 1 unit for standard configurations
• Customized standard products: minimum quantities depend on the level of customization, often 25-100 units
• Fully custom designs: typical first-production runs start at 100-500 units

Use the Request a Quote button on any product page or our main quote page. Tell us the product, quantity, target lead time, and any customization needs.

Our sales engineering team typically responds within 1 business day. For complex custom projects, we'll schedule a call to scope your requirements.

Yes — all products manufactured by Energy Access are RoHS3 compliant and REACH conformant.

Compliance documentation is available on request and can be provided alongside material declarations for your design files.

Many of our chargers are deployed in military and aerospace applications and meet relevant MIL-STD requirements for shock, vibration, EMI, and temperature extremes.

Custom designs can target specific MIL-STD-810 (environmental), MIL-STD-461 (EMI/EMC), and MIL-STD-704 (aircraft electrical power) profiles.

Yes. Selected models (including the SBS series and select power supplies) carry IEC 60601-1 and IEC 60601-1-2 certifications for medical electrical equipment safety and EMC.

We can also engineer custom solutions to meet specific medical device requirements. Our medical-grade line cords (MCUL series) meet hospital-grade NEMA 5-15 standards.

Standard certifications include:

• UL — US safety
• CE — European conformity
• FCC — US RF emissions
• RoHS / REACH — materials compliance

Many products also carry IEC 60601 (medical electrical safety), MIL-STD (military environmental and EMI), and country-specific approvals (CB Scheme, PSE, CCC, etc.). Each product's spec sheet lists applicable certifications.

Yes. Our engineering team can review your battery specs, intended environment, regulatory requirements, and integration constraints to recommend the right approach — whether that's a custom design, modified standard product, or off-the-shelf solution.

There's no charge for an initial consultation.

Typical timeline:

• Design proposal: 2-3 weeks
• Prototype delivery: 6-10 weeks from approved spec
• First production run: 8-12 weeks after prototype approval

Timeline varies by complexity and component availability. Rush options are available — ask sales.

Most standard products can be customized for:

• Housing — material, color (anodized aluminum, custom RAL colors)
• Connectors — input and output options
• Number of bays — single up to 8
• Communication protocols — I2C, SMBus, CAN Bus, Mod Bus, RS-232, single-wire
• LED indicators — state-of-charge, fault, custom states
• Mounting — DIN rail, panel mount, custom
• Branding — labeling, color match

Yes — custom engineering is our specialty. We've designed chargers for medical devices, military equipment, robotics, drones, industrial automation, and security systems.

Our process: you tell us your battery specs, environmental requirements, certifications needed, and target form factor. We propose a design, prototype it, validate against your requirements, and move to production. Lead times depend on complexity.

Yes — most of our standalone products are also available as embedded charger boards (PCBA only, no enclosure). This lets OEMs integrate battery charging into custom equipment housings while leveraging our proven charging algorithms, safety protocols, and certifications.

Ask about our SBS-4002, ICS, ASB, and Pantheon embedded boards.

Yes. Our customizable Lithium-Ion and LFP BMS solutions support packs from 3 to 15 cells, with current ratings from 5A to 50A. Every parameter — cell balancing current, temperature cutoff, layout, form factor — can be tailored to your battery pack.

SMBus and protection-only variants are available, with optional USB-C charging integration.

SMBus (System Management Bus) is the industry-standard communication protocol for smart battery packs. It enables real-time data exchange between battery and charger — temperature, state-of-charge, cycle count, and fault conditions.

Our SBS series desktop chargers, Pantheon large format chargers, and Lithium-Ion BMS all support SMBus Level 3 (the most complete implementation). Non-SMBus chargers are also available for standard battery packs.

Our chargers handle all major rechargeable chemistries:

• Lithium-Ion (Li-ion)
• Lithium Iron Phosphate (LiFePO4)
• Lithium Polymer (LiPo)
• Nickel Metal Hydride (NiMH)
• Nickel Cadmium (NiCd)
• Sealed Lead Acid (SLA)

Multi-chemistry support is standard, with optimized charging algorithms for each.

We design and manufacture three main charger families:

• Desktop chargers — 2 to 8 bays for SMBus and standard battery packs (SBS series)
• Wall plug-in chargers — compact units for portable devices (XSB Bullet series)
• Large format chargers — the Pantheon series, scalable from 60W to 3000W for industrial packs up to 60V and 100A

All are available as standalone products or embedded boards for OEM integration.
