Most real projects are not a stock SKU — EGbatt designs custom LiFePO4 packs to your voltage, capacity, envelope and certification, with everything built in-house.

Overview

EGbatt custom pack work starts from your requirement: voltage, capacity, dimensions, discharge profile, certification target and annual volume. We grade the cells, define the series/parallel topology, select passive or active balancing, design the busbars and enclosure for the duty (stationary IP65, mobile shock-rated, marine IP67), write or integrate the BMS firmware, and validate the assembly on capacity, IR balance and thermal behaviour. Because cell grading, pack assembly, BMS and testing are all in-house, the prototype matches production and the numbers on the datasheet match the units on your dock. Bring a drawing or a load profile; we return a proposal with test data within three working days.

Typical applications

  • OEM equipment: Pack to the device.
  • Vehicle and AGV: Shape and duty.
  • Medical and instruments: Small, certified.
  • EPC systems: System-level packs.

How to specify & buying guide

  • Send voltage, capacity, dimensions, peak/continuous current and certification target — the more precise, the faster the proposal.
  • State the duty (stationary, mobile, marine) so the enclosure and BMS rating fit.
  • Decide passive vs active balancing with us based on pack size.
  • Confirm volume; it sets whether we tool a new enclosure or adapt an existing one.

Engineering & manufacturing at EGbatt

OEM and private-label work is our core. We protect your brand with NDA-backed development, neutral labeling and documentation in your name, while you keep the lithium expertise in-house at EGbatt. From a modified standard pack to a clean-sheet design, the quality system is identical to our own brand.

Certifications & compliance

  • UN38.3 — Mandatory lithium battery transport test (altitude, thermal, vibration, shock, external short). Required for any cross-border shipment.
  • IEC62619 — International safety standard for industrial Li-ion cells and batteries; expected by EU and most APAC buyers.
  • UL1973 — North American safety standard for stationary lithium battery systems.
  • UL9540A — Fire safety test method for ESS installations; often required by US authorities having jurisdiction.
  • IEC63056 — Safety requirements for stationary lithium battery energy storage systems.
  • CE — EU declaration of conformity for the applicable directives.
  • RoHS — Restriction of hazardous substances in the battery and BMS.
  • ISO9001 — Quality management system certification of our manufacturing process.

Frequently asked questions

What do I need to send?

Voltage, capacity, envelope, current profile and certification target; a drawing or load profile is ideal.

Do you build the BMS firmware?

Yes — BMS selection and firmware integration are in-house.

Can you match my enclosure?

Yes — we design or adapt the enclosure to your duty and dimensions.

How fast is a proposal?

Within three working days from a complete spec.
