48V Lithium Battery Energy Storage For Communication Base Stations
48V rack batteries from 2.56 kWh to 10.24 kWh for 4G and 5G base station backup.
Energy Storage For China Mobile
Rack-mount 48 V LiFePO4 batteries for 4G and 5G base station energy storage, supplied into China Mobile projects. Four formats cover 48V 200Ah, 48V 100Ah in 5U and 4U, and 48V 50Ah in 3U, from 2.56 kWh to 10.24 kWh. The 200 Ah model is rated for more than 4000 cycles.
Key Benefits
- More than 4000 cycles on the 48V 200Ah model and more than 3000 cycles at 0.2C with 80% retention on the others
- Charge and discharge capacity efficiency of 96% or better
- Sheet metal case sized to standard 3U, 4U and 5U rack slots
- Already deployed in China Mobile base station projects
Buyers Who Specify This System
- Telecom operators securing backup power for 4G and 5G sites
- Tower companies standardising battery formats across a national estate
- Network integrators replacing lead-acid strings site by site
- Distributors supplying telecom infrastructure projects
What Usually Goes Wrong Without It
- Lead-acid strings lose capacity fast in hot outdoor cabinets and get stolen for scrap value
- Rack space in a base station cabinet is fixed, so capacity has to fit a 3U, 4U or 5U slot
- Mixed battery formats across a network make spares and maintenance expensive
- Backup runtime has to be proven, not estimated, before a site is signed off

From Your Requirement To A Shipped System
The four stages every order of this product passes through.
Site load and runtime survey
Backup hours required per site set the rack format and capacity.
Format selection
3U, 4U or 5U is chosen against the cabinet space actually available.
Pack assembly and BMS pairing
Packs are built at 16S2P and paired with the BMS and communication settings.
Capacity verification
Each pack is capacity tested and logged before it leaves the line.
What We Can Evidence And What We Cannot
Cell Chemistry
Lithium iron phosphate (LiFePO4). We have 20 years of experience producing iron lithium battery cells and hold 452 technology patents in LiFePO4 batteries.
Certification
MSDS and UN38.3 are held as the basis of any certificate. Further market certificates are applied for according to each market policy requirement, so tell us the destination country at quotation stage.
Warranty And Recycling
Two years warranty on lithium battery products. We hold national qualification for lithium battery recycling and are one of four nationally licensed cell recycling enterprises in China.
What Can Be Changed
The model can be customised according to the specific needs of the market. In practice that means voltage window, capacity, enclosure dimensions, connector and charging standard, communication protocol and branding.
We private label your brand, and products can be customised for you. Sole agency is available depending on your project plan, market plan and operation.
Before The First Order
Send four things and we can configure without a second round of questions: the application and duty cycle, the energy required per day or per charge, the voltage window your system expects, and the destination market.
Minimum order quantity normally starts from one 40 HC container. Delivery is within 60 days on a first order and 30 days from the second. Payment is TT or LC at sight depending on the market.
