REDODO 12.8V100Ah Mini Lithium Batteries Instruction Manual

REDODO 12.8V100Ah Mini Lithium Batteries

PRODUCT OVERVIEW

12. BV lOOAh Battery

Operating Voltage: 12.8V

Charging Voltage: 14.4±0.2V
Recommend Charge Current: 20A (0.2C)
Max Continuous Discharge Current: l00A
Max Continuous Load Power: 1280W

Additional Components

• MB- 35/64″ (14mm) Terminal Bolts
  The terminal bolts are used to secure multiple cable lugs to a single battery terminal. The bolts can be replaced with MB bolts of other lengths based on actual needs.

• Insulating Caps for Bolts

BATTERY-PACK MAIN PARAMETERS

HOW TO ESTIMATE THE BATTERY CAPACITY STATE OF CHARGE (SOC)

• The battery capacity could be roughly estimated by its resting voltage (not charging/discharging voltage)CD.
• Since the voltage of each battery is slightly different, and the voltage measurement is affected by the measuring instrument, ambient temperature, etc., the following parameters are for reference only. The actual SOC of the battery is based on the discharge capacity under load.
• Resting Voltage: The voltage is measured after the battery has been disconnected from the charger and loads with zero current, and left alone for 3 hours.

1. Based on the characteristics of LiFeP04 batteries, the voltage measured by all LiFeP04 batteries during charging/discharging is not the real voltage of the battery. Therefore, after charging/discharging and disconnecting the battery from the power source, the voltage of the battery will gradually drop/increase to its real voltage.

SERIES/ PARALLEL CONNECTION

THE PREMISE OF CONNECTION
To connect in series or /and parallel, batteries should meet the below conditions:

1. identical batteries with the same battery capacity (Ah) and BMS (A);
2. from the same brand (as lithium battery from different brands has their special BMS);
3. purchased in near time (within one month).

LIMITATION FOR SERIES/PARALLEL CONNECTION
Support connecting up to 16 identical batteries for up to:

• 4 in series as 48V (51.2V) battery system/
• 4 in parallel as 400Ah battery system.

WHAT TO DO WHEN THE BATTERY STOPS WORKING?

When the battery

It has an 85% chance that BMS has shut it off for protection, and you could try one of the below ways to activate the battery.

General Steps
If the BMS has cut off the battery for protection, follow the below steps to activate it.

1. Cut off all the connections from the battery
2. Leave the battery aside for 30mins
   Then the battery will automatically recover itself to normal voltage (>l0V) and can be used after fully charged.

If the battery is unable to recover itself after the above steps, please try activating by ONE OF BELOW TWO METHODS. After activated (voltage> l0V) and fully charged by the normal charging method, it can be used normally.

• Method 1
  Use a charger with a lithium battery activation function to fully charge the battery.

• Method 2
  Connect a controller that supports 12V LiFePO4 battery charging to charge the battery for 3~ 10s in sunny daytime.
