Lead-acid replacement

Lead-acid replacement — see the key differences first

A 12V 100Ah LiFePO4 battery can replace lead-acid in many deep-cycle systems. The biggest differences usually come down to weight, usable energy, and cycle life. The comparison below is written for cycling applications such as solar, RV, marine, and backup use — not starter batteries.

Weight comparison: 24.25 lbs vs ~60–70 lbs

Much lighter to handle

Peso
24.25 lbs
vs ~60–70 lbs lead-acid

About 1/3 the weight of a typical 12V 100Ah lead-acid battery.

This battery weighs only 24.25 lbs, compared with a typical 12V 100Ah lead-acid battery at roughly 60–70 lbs. That makes transport, handling, and installation easier.

Weight comparison: 24.25 lbs vs ~60–70 lbs

Same size, 2X energy

Usable energy
1280Wh usable
vs ~600Wh usable lead-acid

Up to about 2× more usable daily energy in deep-cycle use.

This battery weighs only 24.25 lbs, compared with a typical 12V 100Ah lead-acid battery at roughly 60–70 lbs. That makes transport, handling, and installation easier.

Lead-acid figures are based on a typical 12V 100Ah deep-cycle lead-acid benchmark. Actual values vary by battery type and usage conditions.

Before replacing a lead-acid battery, confirm these points

These checks are simple, but they prevent most replacement issues.

Size and terminal fit

Confirm battery box size, terminal type, and terminal orientation before installation.

Charger compatibility

Use a LiFePO4-compatible charge profile. Lead-acid presets may undercharge or stop early.

System current and power

Match charge/discharge current to the load, inverter, and controller requirements. Final limits are confirmed in the datasheet.

Applicazioni

Where this 12V 100Ah LiFePO4 battery fits

The battery is designed around solar energy storage and backup use first, where daily charge and discharge is normal. The same unit also works well in RV, marine, and 12V UPS applications that need a reliable deep cycle lithium battery instead of lead-acid.

Application of 12.8v 100Ah solar energy storage
Main application

Stoccaggio dell'energia solare

A deep cycle lithium battery sized for small 12V solar systems — daily PV cycling, off-grid cabins, and small residential backup loops. Pair with a MPPT charge controller set for LiFePO4.

Application of 12.8v 100Ah RV battery

RV & Campervan

Replace lead-acid house batteries to gain more usable energy between charges on road trips and longer stays.

Application of 12.8v 100Ah marine battery

Marine / Boat

Use as a house bank or auxiliary bank where low maintenance and phone monitoring are helpful.

Application of 12.8v 100Ah backup power battery

UPS / Backup Power

For 12V backup and small UPS setups that need longer service life than traditional sealed lead-acid packs.

Bluetooth monitoring · standard

Bluetooth monitoring (standard) — built for commissioning and service checks

Yes, Bluetooth is standard. It is there to help installers and service teams read real battery status quickly during commissioning, troubleshooting, and routine checks.

What the app is used for

Read live values from the BMS on site. Useful for verifying charge settings, diagnosing low runtime, and checking status without opening cabinets or adding extra meters.

Dimensions & compatibility

Dimensions & compatibility — confirm fit before you replace

For lead-acid replacement projects, fit and charging profile decide success. Use this section to confirm the mechanical and electrical checks installers care about.

Dimensions & terminals

Use the current dimension drawing and terminal spec to confirm compartment fit and cable hardware before ordering.

Installer / procurement checklist

Fast checks that prevent rework in retrofits and new builds.

  • Battery compartment fit: inner dimensions, airflow, and hold-down points.
  • Terminal compatibility: confirm lug size, polarity layout, and wrench access.
  • Cable sizing: match to the battery’s allowed charge and discharge current.
  • System voltage window: confirm inverter, charger, and controller accept LiFePO4 voltages.
  • Low-temperature charging: if your site sees freezing temperatures, confirm charging behaviour with us.
Protection & charging

Protection and charging — how to integrate it correctly

Built-in BMS protection helps the battery operate safely, but correct charging profile matters just as much. Use the guidance below to match your charger/controller and avoid common retrofit issues.

  • Overcharge protection Cuts charging when a cell voltage is too high, protecting the pack.
  • Over-discharge protection Disconnects loads before cells drop below safe voltage.
  • Overcurrent protection Limits excessive current from loads or wiring faults.
  • Short-circuit protection Fast response to short-circuit events on the output side.
  • Temperature protection Operating window enforced on both charge and discharge.
  • Cell balancing Keeps cell voltages aligned for more consistent cycle performance.

Three charging ways

Any method works if the charge profile matches LiFePO4. If you share your charger/controller model, we can confirm recommended settings.

Charging time depends on charger size, temperature, and starting SOC. We avoid publishing one fixed “X hours” number because it can mislead in real installations.

FAQ

Common questions before inquiry

Direct answers from a practical, project-support perspective — replacement fit, charging profile, monitoring, and documents.

Yes. It is designed as a drop-in style replacement for 12V lead-acid batteries in deep-cycle applications such as solar, RV, marine, and UPS. Before replacing, confirm battery compartment size, terminal fit, charger compatibility (LiFePO4 profile recommended), and system current/power limits.

Yes. Bluetooth monitoring is included as standard on every unit. You can view real-time voltage, current, temperature, and state of charge (SOC) from a mobile app.

Yes. It supports up to 4S4P configurations — up to four batteries in series and four strings in parallel. This allows higher voltage or larger capacity banks for off-grid solar and backup projects.

Yes. Solar energy storage is one of the main applications. Use it with a PWM/MPPT charge controller configured for a LiFePO4 profile for repeated daily cycling.

Yes. Common use cases include RV house batteries, marine house/auxiliary banks, and 12V UPS/backup cabinets. Confirm physical fit, terminal orientation, and charge/discharge current limits for your system.

Use a charger with a LiFePO4 profile, or a solar charge controller configured for LiFePO4. A standard lead-acid charger may not fully charge the battery or may terminate early.

Available documents include UN38.3, MSDS, CE, and IEC. Additional documents can be discussed based on your destination market and project needs.
