Shenzhen Blumoti Energy Co., Ltd. is a leading Chinese manufacturer and supplier of 12v lead-acid replacement lifepo4 battery. If you are looking to source durable, bulk 12v lead-acid replacement lifepo4 battery from China, feel free to contact our factory for details. Custom orders are welcome.
Product Overview
This 12V lithium iron phosphate battery uses a familiar lead-acid battery case format. It helps distributors and equipment manufacturers upgrade from conventional lead-acid batteries without redesigning the complete battery compartment.
Four capacity options are available:
12.8V 100Ah - 1.28kWh
12.8V 150Ah - 1.92kWh
12.8V 150Ah - 1.92kWh
12.8V 314Ah - 4.02kWh
Models for RV, UPS, golf cart, backup power, and OEM battery replacement projects.
All four models use LiFePO4 chemistry. The rated discharge current is 50A. Maximum discharge current is 100A. The standard charge current is 30A, with a maximum charge current of 50A.
Bluetooth monitoring, an LCD screen, CAN, and RS485 can be added for selected projects. Configuration should be confirmed before production.
Key Features and Buyer Benefits
- Lead-Acid Replacement Form Factor
The enclosure follows common lead-acid battery dimensions and installation formats.
This can reduce mechanical redesign work for RV systems, UPS cabinets, utility vehicles, and existing battery compartments.
Electrical compatibility must still be checked. The required charging voltage is 14.4V, and the listed discharge cutoff voltage is 10.8V.
- Four Capacity Options
The same 12.8V platform is available from 100Ah to 314Ah.
Distributors can cover compact replacement projects, longer-runtime systems, and higher-energy applications with one product family.
- Clear Current Ratings
Every model has the same listed current limits:
- Rated discharge current: 50A
- Maximum discharge current: 100A
- Charge current: 30A
- Maximum charge current: 50A
The larger models provide more runtime. They do not provide a higher rated discharge current.
- Optional Battery Monitoring
Bluetooth can be added for battery status monitoring through a mobile app.
An LCD screen can also be added for local battery information. Available display functions should be confirmed during project evaluation.
- Optional CAN and RS485 Communication
CAN or RS485 communication can be added when the battery must exchange data with a compatible controller, inverter, charger, or host system.
Buyers should provide the equipment brand, model, firmware version, and required protocol before ordering.
- Long-Life LFP Chemistry
The listed cycle life is 6,000 cycles under the stated test conditions.
LiFePO4 chemistry is suitable for applications that require frequent cycling, stable output, and lower routine maintenance than conventional lead-acid batteries

Cycle-life test condition stated in the supplied specification: 100% depth of discharge, 0.5C charge/discharge rate, and 25°C ±5°C.
Actual energy output and service life depend on load, temperature, charging settings, depth of discharge, BMS limits, and operating conditions.
Certification reports and document scope should be confirmed by model and destination market before ordering.
Application Solutions
RV and Camper Auxiliary Power
The battery can replace selected lead-acid house batteries in RV and camper electrical systems.
The 100Ah model suits compact auxiliary loads. The 150Ah and 200Ah versions provide longer backup time. The 314Ah model is intended for projects that need more stored energy in one enclosure.
This series should not be selected as an engine starter battery unless the starting-current requirement has been separately approved.
UPS and Backup Power
The battery can support UPS systems and backup power equipment that operate within the listed voltage and current limits.
Before selection, buyers should confirm:
- Charger output voltage
- Continuous load current
- Maximum load current
- Required backup time
- Available installation space
- Low-temperature operating conditions
Golf Cart and Utility Vehicle Projects
The product can be evaluated for golf carts and low-speed utility vehicles.
Most golf cart systems use a battery bank above 12V. Series connection, parallel connection, controller current, and BMS compatibility must therefore be confirmed before ordering.
Do not assume that a standard 12V model can be connected in series without written technical approval.
OEM Lead-Acid-to-Lithium Conversion
The standard enclosure format is suitable for manufacturers converting an existing lead-acid product line to LiFePO4.
Optional Bluetooth, LCD, CAN, and RS485 functions can support product differentiation and system integration.
Terminal type, case dimensions, communication protocol, branding, packaging, and documentation should be finalized before production.
