Stackable Lithium Batteries
5 kWh And 10 kWh Floor-Standing Stackable Lithium Battery
A vertical stack that starts at 5 kWh and grows to 30 kWh one module at a time.
Product Overview
A vertical stack that starts at 5 kWh and grows to 30 kWh one module at a time. Each module is 51.2V 100Ah with grade A LiFePO4 cells and a smart BMS, and the assembled stack measures 600 x 184 x 1100 mm with roughly 50 kg per module - light enough that two people can carry modules in and build the stack in place. RS232, RS485 and CAN communication keeps it compatible with mainstream hybrid inverters, and the published cycle rating is 6000+.
Key benefits
Why Buyers Choose This Pack
Capacity Becomes A Line Item
Parallel two modules for 10 kWh, three for 15, and on to six and 30 kWh. The customer buys what they can justify today and adds later.
Carried In, Not Craned In
About 50 kg per module means a normal two-person lift up steps and through a doorway, unlike a single large cabinet.
Three Protocols
RS232, RS485 and CAN, so the pack talks to the inverter the installer already sells rather than forcing a change.
Small Footprint For The Capacity
600 x 184 x 1100 mm assembled - a narrow floor strip rather than a wall's worth of mounting area.
Application scenarios
Where It Is Used
- Phased residential storage growing with household load
- Off-grid homes stepping up from a small starter bank
- Solar self-consumption on a hybrid inverter
- Time-of-use tariff shifting where payback sets the module count
- Small commercial backup in shops and workshops
- Replacing an ageing lead-acid bank in stages
Who it is for
The Buyers This Pack Suits
Installers Selling In Phases
Quoting a first phase the customer approves, with a second phase that needs no new site survey.
Homes Without Suitable Wall Space
Where the floor is available and the wall is not.
Distributors Covering Mixed Housing
One module SKU that serves apartments and large homes by changing the count.
Problems it solves
What It Fixes
Guessing At Future Load
An EV, a heat pump or a new occupant changes consumption. A stack absorbs that without replacing the first purchase.
Access To The Install Position
Narrow stairs and tight plant rooms rule out single large cabinets. Modules go in one at a time.
Inverter Compatibility
Three communication protocols cover the mainstream hybrid inverter market instead of one proprietary link.

Packing and documents
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.

Installation guide
Getting It Right First Time
Step 1
Decide the final target capacity at the first order so the base and controller are specified for the full stack.
Step 2
Check the floor is level and can take the loaded stack, and leave clearance for airflow.
Step 3
Send us the inverter model to confirm which of RS232, RS485 or CAN will be used.
Step 4
Keep all modules in a stack the same model and, when adding later, bring the new module close to the existing state of charge before connecting.
Step 5
Set an inverter reserve so the stack is not taken to its floor every night.
Comparison
How It Compares In Our Range
Four products cover the stackable family - the difference is module capacity and the assembled configuration, not the cells or the protocol set.
| 5 kWh / 10 kWh floor-standing stack | 600 x 184 x 1100 mm, 50 kg per module |
|---|---|
| 51.2V 100Ah stackable module | The 5 kWh building block, 540 x 600 x 168 mm |
| 51.2V 200Ah 10 kWh stackable | Fewer, larger modules for the same capacity |
| 20 kWh / 30 kWh stack | Four to six modules for large homes |
FAQ
5 kWh And 10 kWh Floor-Standing Stackable Lithium Battery Questions
How many modules can I stack?
Up to six, giving 30 kWh from 5 kWh modules. The published family is 5, 10, 15, 20, 25 and 30 kWh.
Can I add modules a year later?
Yes, provided they are the same model and the base and controller were specified for the final stack. Tell us the target capacity at the first order.
How much does one module weigh?
About 50 kg, which two people can handle without lifting equipment.
Which inverters does it work with?
It supports RS232, RS485 and CAN. Send your inverter brand and model and we will confirm the protocol before you order.
Stack or wall mount?
Stack where capacity will grow or the floor is easier than the wall. Wall mount where the capacity is settled.
What certificates does it carry?
MSDS, UN38.3, CE, ROHS and UL are listed for the stackable range.
