5 kWh 51.2V 100Ah Powerwall Lithium Battery
The entry point into 51.2V home storage: 100Ah, 5 kWh, wall mounted, with the same grade A LiFePO4 cells and smart BMS as the larger packs in the range.

Product Overview
The entry point into 51.2V home storage: 100Ah, 5 kWh, wall mounted, with the same grade A LiFePO4 cells and smart BMS as the larger packs in the range. It suits an apartment, a small house, or a first phase that will grow by paralleling more units on the same bus. The wall-mounted format keeps the installation tidy, and the 6000+ cycle rating with a five-year warranty means a small pack is not a compromise on service life.

Why Buyers Choose This Pack
A Realistic First Step
5 kWh is often what a customer will approve at the first quotation, and because it is 51.2V the system can grow from there rather than being replaced.
Small Enough To Site Easily
Fits walls where a larger pack would not, which widens the number of properties where storage is practical at all.
Same Cells And BMS As The Big Packs
Cell grade and protection do not scale down with capacity - overheating, overcharge, over-discharge, balancing and short-circuit protection are all present.
Five-Year Warranty At Entry Level
6000+ cycles and a 10+ year service life expectation, with the same warranty as the 30 kWh cabinet.
Where It Is Used
- Apartments and small homes with a modest evening load
- First phase of a residential system that will expand
- Backup for essential circuits rather than the whole house
- Holiday homes and cabins used part of the year
- Small shops and offices closing in the early evening
- Demonstration and showroom systems for installers
The Buyers This Pack Suits
Installers Quoting Cautious Customers
Where a smaller first purchase is what gets the project signed, and expansion keeps the door open.
Apartment And Small-Home Owners
With limited wall space and an evening load that does not justify 10 kWh.
Distributors Building A Range
Carrying the entry size alongside 10 and 15 kWh so the same installer can quote every property type.
What It Fixes
Storage Priced Out Of The Quotation
A 5 kWh entry point gets storage onto the invoice at all, which a 15 kWh proposal sometimes does not.
Small Properties, Small Walls
Not every home has room for a large pack. This one goes where the others cannot.
A First Purchase That Becomes A Dead End
Parallel expansion on the 51.2V bus means the first 5 kWh stays in service when the second is added.

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
Confirm the evening load before assuming 5 kWh is enough - it covers lighting, refrigeration and electronics comfortably, and air conditioning rarely.
Step 2
Send the inverter model so we can confirm the communication protocol before the order.
Step 3
Plan the position so a second pack can hang alongside it without re-routing cable.
Step 4
Set a reserve in the inverter rather than cycling the pack to empty every night.
Step 5
Keep the pack within the datasheet temperature range, especially for charging in winter.
How It Compares In Our Range
Within the residential range, capacity is the only real variable - the cells, BMS architecture, cycle rating and warranty are common.
| 5 kWh wall mount | Apartments, small homes and first phases |
|---|---|
| 10 kWh wall mount | Typical family home |
| 5 kWh stackable module | Same capacity, stacks to 30 kWh later |
| 5 kWh rack module | Same capacity in a 19-inch cabinet |
5 kWh 51.2V 100Ah Powerwall Lithium Battery Questions
Is 5 kWh useful on its own?
For an apartment, a small house or essential-circuit backup, yes. For a home with air conditioning it will be emptied most nights, which is a sizing problem rather than a product problem.
Should I buy this or a stackable module?
Wall mount if the capacity is settled and there is a wall. Stackable if you expect to add capacity in steps and would rather build on the floor.
How many can I parallel?
The wall-mounted range publishes parallel expansion to fifteen units. In practice the inverter and the wall decide the sensible limit - send your target and we will confirm.
Does the five-year warranty apply at this size?
Yes. Cycle rating, service life expectation and warranty are the same across the powerwall range.
Which certificates does it carry?
CE, UL, MSDS, IEC, UN38.3 and ISO are listed for this product.
Can it be supplied under our own brand?
Yes, OEM and ODM are both available, with a sample for approval before bulk production.
