12V 400Ah Lithium LiFePO4 Batteries are an alternative replacement (AR) for most applications currently using a deep cycle Gel, AGM or Flooded Lead Acid battery. The maximum continuous discharge current is 175A and peak discharge current 320A for 5 seconds.

12V 400AH Lifepo4 Battery-Deep Cycle Lithium ion Battery

  • 12v 400ah lithium battery has a Built-in Battery Management Systems (BMS) with power terminal cut-off and recovery. lifepo4 battery 12v 400ah is a high-performing deep cycle battery designed as a "drop-in replacement", this is a plug-and-play option for any application that currently uses a lead-acid, gel, or AGM battery. This lithium iron phosphate (LiFePO4) battery is ready to replace your heavy lead-acid battery bank in your sailboat, RV, or solar energy system. The highest quality lithium chemistry from lithium battery company. The 12V 400Ah LiFePO4 Battery from is a safer, more lightweight alternative to lead-acid in various marine applications.

  • 12V 400Ah battery comes with the Battery Management System (BMS), which protects the battery from unwanted events like an over-charging, over-discharging, over-current, short circuit, and over-temp.

  • The allowed temperature range for charging is from 0°C to +50°C and for discharging -20°C to +60°C - for short, 12v 400ah lithium ion battery should be kept at the room temperature, perhaps a little bit lower - around 20°C is probably the best temperature for both charging and discharging.

  • 12V 400Ah LiFePO4 battery with built-in 250A BMS provides max 5.12kWh energy, and supports max 250A continuous charge & discharge current and max 3.2kW continuous load power. 1*12V 400Ah battery capacity is twice larger than regular 200Ah battery and you could build your battery system with easier operation and no worry about batteries connection. It meets your higher power and longer battery runtime at one time.

  • We adopt Automotive Grade LiFePO4 Cells with higher energy density, more stable performance & greater power, and insist on providing customer with environmentally friendly green power solution. All Ampere Time battery meets UL Testing, CE, FCC, ROHS, PSE, IP65 certifications. Highest grade of battery cell and authoritative accreditation enable Ampere Time battery growing as LiFePO4 battery leader.

  • LiFePO4 battery set you free from battery security issue. It equipped with battery management system (BMS), which protects the battery pack from over charging & discharging, over current, short circuit, and over temp. It is perfect in many off-grid applications, like solar or energy storage system, backup power, RV, security or surveillance systems and more capability of lithium iron phosphate battery is under exploration.

  • LiFePO4 battery provides 4000+ cycles with 10-year lifetime, which is twice times to LiFePO4 battery in market with 2000+ cycles and more than 10 times lifetime of lead-acid battery. Further, Our LiFePO4 battery weighs only 39.12kg / 86.2lbs for one module, only 1/3* the weight of lead acid batteries, more portable and easier in outdoor application.

Safety and economical

Each battery has built in PCM protection board from Over-discharge, Over-charge, Short Circuit etc….

LiFePO4 battery is Environmentally friendly, which will not destroy the ecological environment, also have no memory effects.

Excellent discharge characteristics

Have low internal resistance and high flat voltage characteristics during strong current discharge, which ensures a wider application field.

Long cycle life

Provide long storage life with few limiting conditions. It offers problem-free charge after long storage, permitting to use in a wide range of applications.

Heavy Duty - Built in Battery Protection System

Lithium batteries have a built-in Battery Protection System (BPS) designed to prevent damage to the cells from almost any external accidental occurrence that would normally cause damage. The internal BPS will automatically disconnect to prevent damage to the cells if the battery drains below 10 volts. It will automatically reconnect when the charger is turned on. This protects the battery from over-discharging and damaging the cells. This technology also protects the battery from overcharge, short circuit and reverse polarity.

Internal Features:

  • Low Voltage Protection Switch - Automatically disconnects around 10V

  • Over Voltage Protection Switch - Automatically disconnects around 14.8V

  • Short Circuit Protection Switch - Automatically disconnects

  • Reverse Polarity Protection Switch - Automatically disconnects

  • Internal cell balancing - Automatically balances cells

  • Charge Balancing - Independent balancing for multiple batteries connected in parallel or in series.

  • This Battery Protection System is designed to last throughout the life of the battery and provide reliable power for thousands of cycles.

Compatible with 20+ Inverter Brands
