ALUX LFP12-100 12.8V 100Ah LiFePO4 Deep Cycle Battery

ALUX LFP12-100 is a 12.8 V 100 Ah LiFePO4 deep-cycle battery with an integrated BMS, storing 1,280 Wh and rated for more than 5,000 cycles. Measuring 328 × 172 × 220 mm and weighing about 10.5 kg, it replaces a 12 V lead-acid battery of similar footprint in solar, RV, marine and off-grid systems.



Product Overview

The ALUX LFP12-100 is a 12.8 V 100 Ah lithium iron phosphate (LiFePO4) deep-cycle battery that stores 1,280 Wh in a 328 × 172 × 220 mm case weighing about 10.5 kg. An integrated BMS manages the pack internally, and the battery is rated for more than 5,000 cycles at 0.5C with 50% depth of discharge. It is built as a drop-in replacement for 12 V lead-acid batteries of a comparable footprint, so existing cabinets, cabling and chargers can usually stay in place while usable capacity and service life go up.

Key Features

  • Lighter weight — about 40% of the weight of a comparable lead-acid battery, so retrofits stay manageable and one person can lift it into place.
  • Higher power — up to twice the sustained power of an equivalent lead-acid block, with 100 A continuous and 300 A peak discharge for inverters and motor loads.
  • Longer cycle life — more than 5,000 cycles at 0.5C with 50% depth of discharge, and roughly five times the float and calendar life of lead-acid.
  • Superior safety — LiFePO4 chemistry removes the explosion and combustion risk that lead-acid and other lithium chemistries carry under impact, overcharge or short circuit.
  • Integrated BMS — battery management is built into the pack, so no external BMS hardware or configuration is required.
  • Series up to 4 units — four batteries in series give a 51.2 V 100 Ah bank for 48 V inverters and off-grid systems.
  • IP65 enclosure — sealed against dust and water jets for outdoor cabinets, boats and vehicles.
  • Low self-discharge — under 3% per month, so a charged battery survives storage and off-season parking without a maintenance charge.
