| Feature | Standard Telecom Rack Fit | Redway Battery Specs |
|---|---|---|
| Height | 3U-5U | 3U 51.2V 100Ah |
| Depth | 400-600mm | 420mm slimline |
| Comm | CAN/RS485 | +Modbus, SNMP |
| Charge Rate | 0.5C-1C | 1C continuous |
What Charging Speeds Are Possible?
Rack lithium batteries achieve 1C charging (full in 1 hour) via advanced BMS thermal management.
Redway Battery’s LiFePO4 cells handle 1.5C peaks safely, ideal for peak-demand telecom. Wholesale units include auto-cutoff at 100% SOC.
Compared to VRLA’s 8-12 hour recharge, lithium cuts recovery time by 90%. China factories optimize for high-rate without degradation.
Why Choose LiFePO4 for Fast-Charging in Data Centers?
LiFePO4 offers thermal stability up to 60°C, 80% DoD, and no fire risk during 1C charging.
Redway Battery’s ISO 9001-certified packs last 10+ years, slashing TCO by 50%. As an OEM supplier, they customize for UPS integration.
Data centers gain space savings (50% vs lead-acid) and predictive maintenance via MES monitoring.
How to Select Capacity for Backup Needs?
Calculate load (kW) x hours / voltage; choose 50-500Ah modules.
Redway Battery advises 100Ah for 4-hour telecom backup, scalable to 5kWh+. Test via samples from China wholesalers.
Factors: temperature derating (-20°C to 60°C), parallel limits (16p).
Which China Manufacturers Offer Wholesale OEM?
Shenzhen factories like Redway Battery lead with 4 plants, 100,000 ft², and 13+ years experience.
They provide ODM for custom BMS, faceplates, and 4-week delivery. Verify ISO/CE/UL certifications.
Redway excels in telecom volumes (1000+ units), global shipping.
Can They Integrate with Existing Rectifiers?
Yes, via adjustable 48-54V profiles and universal CAN/RS485.
Redway Battery matches Delta/Eltek rectifiers; firmware updates on-site. No hardware mods needed.
