51.2V 100Ah Stackable Lithium Battery Module

The 5 kWh building block of the stackable family.

51.2V 100Ah stackable lithium battery module front view

Product Overview

The 5 kWh building block of the stackable family. One module is 51.2V 100Ah in a 540 x 600 x 168 mm case at about 53 kg, and modules stack to 10, 15, 20, 25 and 30 kWh. Compared with rack-mounted and wall-mounted batteries, the stackable format is the flexible one: it expands in the smallest useful increment, and the assembly can be moved rather than being a fixture of the building.

Key benefits

Why Buyers Choose This Pack

The Smallest Sensible Step

5 kWh increments mean the bank can be matched closely to the load instead of jumping in 10 kWh blocks.

Stock One Part Number

Distributors can cover every capacity in the family from a single module SKU.

6000+ Cycles Per Module

Grade A LiFePO4 cells with a smart BMS in each module, so the whole stack shares one ageing profile.

Not A Fixture

A stack can be dismantled and moved. A wall-mounted pack, realistically, cannot.

Application scenarios

Where It Is Used

  • First phase of a phased residential storage project
  • Off-grid systems built up over several seasons
  • Solar self-consumption with a modest evening load
  • Small commercial backup added to over time
  • Replacement of a lead-acid bank in stages
  • Demonstration systems for installers and showrooms
Who it is for

The Buyers This Pack Suits

Installers Quoting Phased Work

Where each phase has to be small enough to approve without a finance conversation.

Distributors Minimising SKUs

One module covering 5 to 30 kWh across the whole customer base.

Self-Builders And Off-Grid Owners

Adding capacity as budget and load allow.

Problems it solves

What It Fixes

Capacity Steps That Are Too Coarse

Jumping 10 kWh at a time overshoots many homes. 5 kWh modules land closer to the actual requirement.

Committing To A Fixed System

A stack keeps the options open on both capacity and position.

Stock Complexity For Resellers

One module, many system sizes, one set of spares.

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 We do not publish a fixed carton specification here because it changes with order size and freight mode.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

Specify the final target capacity at the first order so the base and controller suit the full stack.

Step 2

Plan the floor area and clearance for the final module count, not the first one.

Step 3

Confirm the inverter protocol with us before ordering.

Step 4

When adding a module later, match its state of charge to the running stack before connecting.

Step 5

Hold a small reserve in the inverter so the bank is not emptied daily.

Comparison

How It Compares In Our Range

The stackable family shares cells, protocols and cycle rating - module size and assembled capacity are the variables.

FAQ

51.2V 100Ah Stackable Lithium Battery Module Questions

How many of these make 30 kWh?

Six modules at 5 kWh each. The published family is 5, 10, 15, 20, 25 and 30 kWh.

Can I buy one now and more later?

Yes - that is the design intent. Specify the final target at the first order so the base and controller are right.

What does a module weigh?

About 53 kg, in a 540 x 600 x 168 mm case.

Which inverters is it compatible with?

It supports RS232, RS485 and CAN. Send the inverter brand and model and we will confirm.

Stackable or wall mounted for a 10 kWh system?

Stackable if the capacity is likely to grow or the wall is unsuitable; wall mounted if the capacity is settled and wall space is available.

What certificates come with it?

MSDS, UN38.3, CE, ROHS and UL.

Applications
