Five Battery Platforms, Engineered on One Factory Floor

EMS-ESS builds five product lines under one roof: home storage batteries, 19-inch rack modules, e-bike and scooter packs, RV and marine deep-cycle batteries, and custom smart BMS. Every line shares the same A-grade cell sourcing, the same laser-welding line and the same export compliance pack — so your second program starts faster than your first.

Shared Platforms

One Voltage-Platform Matrix Across Every Line

Each platform is a cell count, not a marketing name. 12V is 4S LiFePO4, 24V is 8S, 48V storage is 16S at 51.2V, and 72V light-electric packs are 20S Li-ion. The 36V class runs 10S Li-ion or 12S LFP (38.4V) for trolling-motor systems; 60V moped packs are quoted per project between the 48V and 72V platforms.

Storage platforms run EVE LF280K (280Ah, ~6,000 cycles, ≤0.25 mΩ internal resistance) or CATL 314Ah (~180Wh/kg, 6,000–7,000+ cycles) A-grade prismatic cells — every lot delivered with capacity and internal-resistance reports. Light-electric platforms run Samsung 50G 5000mAh or LG 4800mAh 21700 cells, with LFP available where 2,000+ cycle life matters more than weight.

Custom Build Process

From Spec Sheet to Container in Four Steps

Requirement Review

Send voltage, capacity, application and target annual volume. An engineer — not a salesperson — classifies your spec against the platform matrix and replies within 24 hours.

Proposal & Samples

Specification sheet and quotation in 2 working days. Sample packs built in 15–20 days with the agreed BMS profile, cell brand and enclosure.

Production

30% deposit starts the line. 100–500 units deliver in ~15 working days; full containers in 25–30 days, with cell-lot traceability on every pack.

Export Delivery

UN-certified packaging under IMDG P903 for sea freight, state of charge set to 30% for air. UN38.3 test summary, MSDS and DG declaration travel with the shipment.

Buyer Questions

Capabilities, Answered by the Numbers

Can you build a voltage or capacity outside the platform table?

Yes. Standard-platform batteries start at 10 units so you can pilot a market. Fully custom packs — own mold, non-standard voltage, special enclosure or connector — start at 200–500 pcs depending on the line, and sample fees are credited against your first order.

Do you make the BMS in-house or buy it in?

In-house. Our BMS team covers 3S–32S boards from 30A to 500A with UART, RS485, CAN and Bluetooth 5.0, and maintains protocol libraries for Deye, Victron, Pylontech, Growatt and SMA inverters. Custom register mapping is firmware work for us, not a sourcing problem.

Which certifications come as standard?

Every line ships with UN38.3 (all 8 transport tests), CE and a 16-section MSDS. IEC 62133-2 comes through the CB scheme for consumer-adjacent packs, IEC 62619 for industrial LFP, and UL 1973 runs as a per-project program on the rack and ESS lines.
