A rechargeable lithium ion custom battery manufacturer


The Lithium Battery Company Cell Model IFR26650 / IFR32650 LiFePO4 has a capacity of over 6AH with 3000-5000 Life Cycles. The ratio of weight against energy is 130Wh/Kg. The Life of the battery can reach up to 15 years. Each cell is bolted together for strength and efficient electrical conduction.


1. Upon high temperature, the diaphragm shuts down the inner ion cell.

2. If the cell casing senses high internal pressure, the positive and external current will cut off.

3. If the internal pressure is over 1.5 Mpa, the valve will safely discharge the pressure.


We match and group our cells together during assembly based on 10 Factors.

1. Self Discharge
2. Voltage
3. Inner Impedance
4. Capacity
5. Cycle Life
6. Platform
7. Constant Current Rate
8. Cell Power Control
9. Parallel Module Control
10. Finished Battery Control


Each battery cell is individually protected & monitored by our advanced BMS, ensuring the best performance possible. Each internal cell also has a built in fuse installed for extra safety protection. The fuse will disconnect if the system senses any malfunctions.

Coremax Battery Management System (BMS) will protect the battery from almost any external accidental occurrence that would normally cause damage to a lithium battery. The Coremax internal BMS will automatically disconnect 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. Coremax BMS protects the battery from over-charge, short circuit and reverse polarity.

The BMS is military grade for maximum strength and reliability in the world’s most demanding environments. Designed to handle high amp loads the Coremax BMS allows customers to use 100% of the rated capacity while maintaining maximum performance and life expectancy of the battery.

Every battery from Coremax includes internal protection that protects against the following:

Low Voltage Protection Switch
– Automatically Disconnects at 10V

Over Voltage Protection Switch
– Automatically Disconnects At 15.8V

Short Circuit Protection Switch
– Automatically Disconnects

Reverse Polarity Protection Switch
– Automatically Disconnects

Internal Cell Balancing
– Automatically Balances Cells During Charge And Discharge
