5kWh Battery LiFePO4 48V 100Ah ESS Battery With RS485 And CAN Communication

Model: ESS48100. Dimension: 442*470*150mm.

Key Benefits

Cycle Life

The LiFePO4 Battery Packs range is published at more than 2000 cycles with 80% capacity remaining at 100% DOD.

Stated Electrical Data

Nominal voltage 51.2V, typical capacity 100Ah (5KWH). The complete parameter table is published below, not summarised.

Built-in Protection

Automatic protection for over-charge, over-discharge, over-current and over-temperature, with internal cell balancing.

Working Range

Operating temperature is published per state. Charge: 0~45℃; Discharge: -20~60℃; Storage: -10~45℃.

Built To Order

Capacity, arrangement, case, terminal, cable, connector and custom logo are all specified by the customer. Dimensions are made according to the device's request.

Application Scenarios

Used across solar street light assemblers who buy a finished 12v or 24v pack, energy storage integrators needing 48v modules with rs485 or can.

Who It Is For

  • Solar street light assemblers who buy a finished 12V or 24V pack
  • Energy storage integrators needing 48V modules with RS485 or CAN
  • Equipment builders replacing a sealed lead acid block of a fixed size

Problems It Solves

  • Packs that fit the electrical spec but not the box
  • Systems with no cell balancing, where one weak cell ends the pack
  • Lead acid weight in a product that has to be carried or pole mounted

Customization Options

Sunder is an OEM and ODM manufacturer. The list below is what is decided by the customer rather than by us.

  • Series and parallel arrangement to reach the voltage and capacity you need
  • Case, terminal and cable length to match the equipment it replaces
  • Connector fitted to your mating part
  • Custom logo and label
  • Dimensions made according to the device's request
What we need from you. Voltage, capacity or run time, peak current, the space available, the connector on your board and the operating temperature range. A drawing or the pack you use now answers most of these at once.

Use Guide

  1. Charge with CC then CV

    Charge at constant current, normally 0.2C to 0.5C, until the cell reaches 3.65V, then hold that voltage until the current tails off. At pack level that is 55~56V.

  2. Respect the charge floor

    Charge between 0℃ and 45℃. Charging a frozen pack is the most common way an outdoor battery is damaged, and it is a controller setting.

  3. Do not rely on the protection board

    The board is a backstop against faults, not a charging strategy. Set the charger correctly first.

  4. Store around 20℃

    Store in the shipment state at roughly 20℃. The storage window per duration is published in the parameter table.

Questions About The 5kWh battery

What are the nominal voltage and capacity of the 5kWh battery?

Nominal voltage 51.2V and typical capacity 100Ah (5KWH). The full parameter table is published on this page.

How many cycles does it give?

The LiFePO4 Battery Packs range is published at more than 2000 cycles with 80% capacity remaining at 100% DOD.

What charge voltage should I use?
