Rack Mount 48V 50Ah Lithium Battery
The smallest module in the 48V range: 50Ah, 2400 Wh, 27 kg, in the same 482 x 480 x 132 mm rack case as the 100Ah unit.

Product Overview
The smallest module in the 48V range: 50Ah, 2400 Wh, 27 kg, in the same 482 x 480 x 132 mm rack case as the 100Ah unit. It is designed for server rack applications and long-lasting power supply in data centres and telecom systems, where the load is modest, the hold-up requirement is short, or the bank is built from several small modules for redundancy rather than one large one.



Why Buyers Choose This Pack
27 kg Per Module
The lightest module in the 48V range, which matters where a site is reached on foot or up a tower access stair.
Fine Capacity Steps
2.4 kWh increments let a bank be matched to the load instead of overshooting it.
Redundancy Through Module Count
Several small modules mean one failure removes a fraction of the bank rather than half of it.
Same Case As The 100Ah
One rack layout, one mounting arrangement, two capacities - useful across a mixed estate.
Where It Is Used
- Small access network cabinets
- Server rack and comms room backup at modest load
- Security and monitoring system UPS duty
- Repeater and relay sites with low power draw
- Redundant banks built from multiple small modules
- Pilot installations before a larger rollout
The Buyers This Pack Suits
Operators With Small Sites
Where a 4.8 or 10 kWh module is more battery than the load justifies.
Data Centre Teams Building Redundancy
Preferring several modules over one, so a single failure is a small loss.
Integrators Handling Access Constraints
Sites where 27 kg per unit is the difference between a one-person and a two-person visit.
What It Fixes
Oversized Backup For A Small Load
Paying for capacity a site will never use is a common mistake. 2.4 kWh modules right-size the bank.
Single Points Of Failure
A bank of small modules degrades gracefully; one large module does not.
Physical Access To Site
The lightest module in the range is the one that gets carried to the hardest sites.

How It Ships And What Comes With It
Packing And Shipping
Packing follows UN38.3 requirements for lithium battery transport, and the carton and pallet arrangement is confirmed with the quotation for your quantity and destination. We do not publish a fixed carton specification here because it changes with order size and freight mode.
Documentation
UN38.3 and the MSDS travel with every lithium shipment, and the certificates listed in the specification table above are supplied for the model you order. Tell us the destination market at the quotation stage so the document set is planned rather than chased after the goods are built. Where a certificate we do not hold is required, we will say so rather than promise it.
Manufacturing
This pack is built at Shenzhen Sike Power Technology Co., Ltd. in Da Peng New District, Shenzhen, with cell grading, assembly, BMS integration, aging test and final inspection carried out in house. Only brand-new grade A LiFePO4 cells and a top-brand smart BMS go into it.

Getting It Right First Time
Step 1
Work out the site load first - a bank of 2.4 kWh modules is only right if the load is genuinely small.
Step 2
Configure the rectifier for a LiFePO4 charge profile and set up RS485 or CAN communication.
Step 3
Confirm the cabinet provides the environmental protection, since the module itself is IP20.
Step 4
Check the 50A BMS rating against the real peak load, not the average.
Step 5
Leave rack units free for the modules that will be added as the site grows.
How It Compares In Our Range
Three capacities on the same 48V architecture; choose by load and hold-up rather than by price per kWh.
| 48V 50Ah | 2.4 kWh, 27 kg, 50 A BMS, small sites |
|---|---|
| 48V 100Ah | 4.8 kWh, 40 kg, 100 A BMS, standard sites |
| 48V 200Ah | 10 kWh, long hold-up, parallels to 40 kWh |
| 48V 50Ah server rack version | The same 2.4 kWh module in telecom trim |
Rack Mount 48V 50Ah Lithium Battery Questions
Is 2.4 kWh enough for a site?
It depends entirely on the load. A 300 W site gets several hours; a 1.5 kW site gets minutes. Send the load and the hold-up target and we will tell you the module count.
Can I mix 50Ah and 100Ah modules in one bank?
Keep a bank uniform. Mixing capacities on one bus is not the clean way to build it - tell us the target and we will specify one consistent bank.
What is the BMS current rating?
50 A. Check it against the site's peak draw rather than the average, particularly if there is a conversion stage involved.
Does it fit a standard cabinet?
It is a 19-inch rack module at 482 x 480 x 132 mm with a slim profile - the same case as the 100Ah version.
How many can be paralleled?
The telecom range publishes parallel operation up to fifteen units. Confirm the arrangement with us for your bank.
Which certificates apply?
MSDS, UN38.3, CE, ROHS and UL.
