Rack-cabinet energy storage, 24–51.2 V.
Purpose-built LiFePO4 batteries for telecom, UPS, solar and central-office racks, supplied through our dedicated battery-pack manufacturing partner Three voltage classes — 24 V, 48 V and 51.2 V — with 2000+ cycles at 100% DOD and a 10-year design life. Packs parallel up to 16 units, self-discharge is below 3% per month, and the cells tolerate ambient heat up to +60 °C. The lightweight LiFePO4 chemistry cuts weight to about one third of an equivalent sealed lead-acid bank.
Pick the bus voltage your rack already runs.
Each unit ships as a self-contained pack with built-in BMS and CAN/RS485 communication, ready to parallel into larger banks. The LiFePO4 cells deliver 2000+ cycles at 100% DOD, cutting replacement frequency against lead-acid.
24 V 100 Ah
2.56 kWh for 24 V DC systems and solar street-light banks. Rack-mount footprint with front terminals.

All figures below come from the partner catalog (Residential Energy Storage Battery Product Catalog). Where a specific unit is not listed in the catalog, we say contact sales rather than estimate — this keeps the table honest for buyers quoting against a formal tender.

Our battery-pack manufacturing partner is ISO9001-certified and invests 10% of annual profit in R&D. The Dongguan factory runs four standardized lines at 30,000 cells and 2,000 packs per day — average monthly output of 12,000 packs, peaking at 52,000 — and every main model ships with CE, UN38.3 and MSDS documents.
How our battery pack partner ships.
Our battery-pack manufacturing partner runs four standardized lines at 30,000 cells and 2,000 packs per day, with ISO9001 quality control and a US$2 million product liability policy from Ping An insurance.
Standard sample
Off-the-shelf packs are sampled in 3 days, so you can validate voltage, capacity, self-discharge and BMS behavior before committing to a full bank.
Custom sample
Modified enclosures, connectors or labeling are sampled in 15 days before tooling is committed.
Mass production
Approved designs enter mass production with a 20-day lead time across four lines at 2,000 packs per day, backed by CE, UN38.3 and MSDS documents.
