BASIC INFORMATION

Lifepo4 Battery 12v 400ah :

[Versatile installation options] – IP65 rating supports all weather conditions for both indoor or outdoor installations.
[1/3 Lightweight & 20-year Lifetime] - Our 12V RV battery can run over 8000 cycles, which is quite superior to lead acid battery with 200~500 cycles (3-year lifetime). Plus, the lifepo4 battery is only 1/3 the weight of a lead acid battery at the same capacity.
[High-Performance BMS] - Lifepo4 battery 12v 400ah has built-in BMS to protect it from overcharge, over-discharge, over-current, temp, and short circuits. Without memory effect, no matter what state the battery is, it can be used as soon as it is charged.

CALT BATTERY CELLS

Lifepo4 battery 12v 400ah has exceptional quality since they are assembled by Automotive Grade LiFePO4 Cells with UL Testing Certificated, which make them higher energy density, more stable performance, greater power, and excellent 1%-3% self-discharge rate.

BMS SYSTEM

  • Harveypower's BMS system monitors and regulates 12v rv battery charge and discharge status. The monitored battery characteristics include the detection of battery type, voltage, temperature, capacity, state of charge, power consumption, remaining operating time, charge cycles, and more.
  • It can process and monitor up to 16 lifepo4 battery 12v 400ah at the same time, provide a battery balancing function, manage different batteries with the same charge and discharge requirements, and ensure the optimal utilization of the remaining energy in the battery.

BATTERY WITH GRADE A CELLS

Our lithium battery for golf trolley used the KAT Lifepo4 battery cells (No.1 in world), over 6000 cycles, 20+ years lifespan.

INTELLIGENT  PRODUCTION

The production line adopts automatic equipment such as fully automatic welding to reduce more manual errors and speed up the production process.

FUNCTION CUSTOMIZATION

  • LED Display (Optional)

Build an LED display outside the product group to visualize the overall data and status of the battery pack. You can also DIY the operation functions of the display according to your needs.

  • Self-heated Function (Optional)
The BMS system can be set with a self-heating function to make the battery system suitable for lower temperatures. 
When the temperature is below 0°C, through self-heating, the temperature of the battery can rise to above 10°C within a few tens of seconds, thereby activating the normal application of the battery. 
Start heating temperature: ≤0℃. Stop heating temperature: ≥10℃.
  • Bluetooth Function (Optional)
Can communicate with BMS in wireless mode. Users can connect the battery pack via Bluetooth, which allows visualizing all-important battery information such as voltage, current, temperature, SOC, SOH, errors, etc. 
Some parameters and switch systems can also be controlled remotely, making everything easy to use and manage.
  • State of Health (Optional)
It can detect and reflect the battery capacity, health, and performance status with the accumulation of battery usage time and the impact of the environment, effectively guiding how to maintain the battery. 

Not only can we know whether the remaining available capacity of the battery can meet our demand for the total temporary power consumption, but also know when each single battery and battery pack needs to be replaced and repaired.
