OSM battery, the Lifepo4 battery manufacturer, has released the new compact and affordable 48v lithium ion battery Ground Eco that provides homeowners with a premium OSM solution in flexible features.
The OSM Ground Eco is a 48v lithium iron phosphate (LiFePO4)battery for usage with an external inverter. Thanks to its modular design the Battery grows with its requirements:
• LFPECO2800 (2.6 kWh)
• LFPECO5600 (5.2 kWh)
• LFPECO11200 (10.4 kWh)
All OSM Ground Ecosystem can be extended with the 48v lithium ion battery modules LFPECO2800 at any time. In series connection of 2 – 8 battery modules. And in parallel can add max 16 modules.
How does 48v li-on battery the work?
For the use of 48v lithium iron phosphate batteries, monitoring by an inverter to charge and discharge. They are not generating electricity, but storing energy from the grid or solar energy. In the event of a power outage, the 48v lithium ion battery will discharge, creating a self-sustaining personal grid that uses the stored energy to power your home.
Key things to know about the 48v lifepo4 battery
Chemistry
The OSM Ground Eco is a lithium-ion storage product. Specifically, it is 48v lifepo4 battery. This is one of the most common lithium-ion battery technologies, and for good reason: relative to other types of batteries, LFP batteries are known for their high energy density (the amount of energy they can store relative to the physical space they take up) and increased safety.
Size
The dimension(W/H/D) of B is 420mm* 207mm*420mm, just like a small table, which can easily matches with your furniture. With a ground stand design. OSM 48v LiFePo4 solar battery can be installed to any place you want at home or office. Easy to move.
Power and Capacity
One module of OSM Ground Eco capacity is 2.6kwh, the battery power is 50ah,voltage 51.2v. LFPECO-L used in parallel, max parallel to 16 packs. And LFPECO-H used in series ,can series to 2-8 modules. The best-selling is adding 4 modules to get a 48v 10kw lifepo4 battery module.
Flexible to plus
Due to the flexible design of this battery, you can easily increase this 48v battery. Extend anytime,
adapt to new requirements.
Warranty coverage
Warranty period: 10 years
Guaranteed end of warranty capacity: 70%
With 10 years long warranty time, just enjoy your no worry electricity time.

What a modular 48V battery pack is
A modular pack is built from identical units that can be combined on site, so the system grows with the requirement instead of being replaced. The OSM Ground Eco follows that idea with three module sizes:
| Module | Energy | How it is used |
|---|---|---|
| LFPECO2800 | 2.6 kWh | Single starter module, or the expansion unit |
| LFPECO5600 | 5.2 kWh | Two modules, typical small-home install |
| LFPECO11200 | 10.4 kWh | Four modules, full evening and night cover |
Every unit runs on the same 48 V bus, so capacity is added in steps without changing the voltage or the inverter.
Series and parallel limits
- Series — modules can be connected 2 to 8 in series to raise the system voltage within the pack’s supported range.
- Parallel — up to 16 modules can be paralleled, so capacity scales well beyond a single module.
- Equal state of charge before connecting — paralleling mismatched modules causes circulating currents and uneven ageing.
- One BMS to arbitrate — the master unit monitors the modules and reports the aggregate limits to the inverter.
The protection logic that makes multi-module systems safe is the same as for any lithium pack — see BMS for a lithium battery pack.
Ground-mounted vs wall-mounted 48V batteries
| Format | Advantage | Site requirement |
|---|---|---|
| Ground / stacked | Easy to add modules, no wall load | Floor space, level surface |
| Wall mount | Compact, out of the way | A solid wall rated for the weight |
| Rack mount | Dense, serviceable, scalable | A cabinet and a plant room |
The wall-mounted equivalent in the same voltage class is our 48 V 100 Ah / 200 Ah powerwall.
Applications for a 48V modular pack
- Home backup and solar self-consumption, expanded module by module
- Small commercial premises with an evening peak
- Off-grid cabins where capacity is added as load grows
- Retrofit of an existing 48 V inverter system
Whichever the application, the inverter has to be configured for a 16S LiFePO4 charge profile; the values are listed in how to configure an inverter for a lithium battery.
48V modular battery FAQs
Can I add modules to a 48V battery later?
Yes, that is the point of a modular design. Add modules in parallel, matching their state of charge first, and the master BMS includes them in its aggregate limits.
How many 48V battery modules do I need?
Base it on the nightly load. A 5–6 kWh requirement is met by the 5.2 kWh module or two 2.6 kWh units; a full night of an average home needs the 10.4 kWh configuration.
Is a ground-mounted battery as good as a wall-mounted one?
Electrically identical — the difference is mechanical. Ground formats make expansion and servicing easier; wall formats save floor space if the wall can take the weight.
