12V And 24V Lithium Batteries
12V 8Ah LiFePO4 Battery
A 0.95 kg drop-in replacement for the 12V 8Ah lead-acid and AGM blocks used in UPS units, electric bicycles, small solar systems and portable electronics.
Product Overview
A 0.95 kg drop-in replacement for the 12V 8Ah lead-acid and AGM blocks used in UPS units, electric bicycles, small solar systems and portable electronics. The lead-acid equivalent weighs about 2.4 kg and lasts a fraction as long; this pack publishes 2500+ cycles and a service life up to ten years, with a low self-discharge rate that suits equipment left standing between uses.
Key benefits
Why Buyers Choose This Pack
0.95 kg Instead Of 2.4 kg
In handheld and portable equipment the weight difference is the product difference.
2500+ Cycles
For a UPS or an e-bike battery replaced every couple of years, that changes the replacement economics entirely.
Low Self-Discharge
Equipment that sits unused for months still works when it is picked up.
Drop-In Format
Replaces the 8Ah AGM block the equipment was designed around, without modification.
Application scenarios
Where It Is Used
- UPS and standby power units
- Electric bicycles and light mobility equipment
- Small solar and lighting systems
- Portable electronics and test equipment
- Security and alarm system backup
- Medical and monitoring devices using 12V blocks
Who it is for
The Buyers This Pack Suits
Equipment OEMs
Replacing AGM blocks in a product design where weight and service life both matter.
Service And Maintenance Companies
Standardising a longer-life replacement across an installed base of UPS units.
Distributors
Carrying the small-format end of the lithium range alongside the deep cycle packs.
Problems it solves
What It Fixes
Frequent AGM Replacement
Small lead-acid blocks fail regularly and quietly. 2500+ cycles changes the maintenance schedule.
Weight In Portable Equipment
Two and a half times lighter is a design advantage, not a specification detail.
Flat Batteries After Storage
Low self-discharge means the device still runs after months on a shelf.

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 We do not publish a fixed carton specification here because it changes with order size and freight mode.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
Confirm the equipment's charger has a LiFePO4-compatible profile or a suitable voltage limit.
Step 2
Check the physical envelope and terminal type against the block being replaced.
Step 3
For OEM use, tell us the volume and the case requirement and we will quote the specification.
Step 4
Store at partial charge if the equipment will be shelved for a long period.
Step 5
Do not use in a cranking or engine-start application.

FAQ
12V 8Ah LiFePO4 Battery Questions
Will it fit my UPS?
It is a drop-in replacement for 12V 8Ah lead-acid blocks. Check the case dimensions and terminal type against the existing battery, and confirm the UPS charging voltage suits LiFePO4.
Can my existing charger handle it?
It depends on the charge profile. Send the equipment model and we will advise rather than guess.
How long will it last?
2500+ cycles with a service life up to ten years, against a lead-acid block that typically lasts a few hundred cycles.
Is it suitable for an e-bike?
It is used in electric bicycles among other applications. Tell us the voltage and current requirement of your controller so we can confirm the fit.
Can I buy these in volume with our branding?
Yes. OEM label and packaging are available, with a sample approved before bulk production.
Which certificates apply?
MSDS, UN38.3, CE, ROHS and UL.
