Caution About lithium battery

military batteries for sale
  • Lithium ion battery are very sensitive to charging characteristics and may explode if mishandled.
  • Make sure user has enough knowledge on Li-ion rechargeable batteries in Charging, discharging and assembly before use.
  • We are not responsible for any damage caused by misuse or mishandling of these Li-ion batteries.
  • Strongly suggest that you use our smart Li-ion battery charger to recharge The battery pack.
  • Never use conventional DC adapter to charge the battery module.

Thanks to its higher voltage per cell and higher energy density, rechargeable lithium ion batteries are becoming popular for 12v li ion battery packs for applications where dimension, weight and run-time are important.

Make a 12 volt rechargeable lithium battery pack

Rechargeable lithium batteries produce 3.7 or 3.2 volts, depending on the type of battery and the chemicals it uses. To make batteries with higher voltages, manufacturers link identical batteries in a series circuit. In this way the voltages of the individual batteries are added together, so three 3.7-volt battery cells become one 12-volt battery (3.7x 3 = 11.1 volt). You can use the same electrical technique to create your own battery packs at home. Doing so requires basic math and no electronic skills.

Select the type of batteries from which to create a 12 volt rechargeable lithium battery pack. You might consider their size, shape or amp/hour capacity to be important, or you may just choose the batteries readily available where you live. It is important to use identical batteries in your pack. They must all have the same voltage and current characteristics.

Calculate how many batteries you need by dividing 12 by the voltage of the batteries.

Link together the batteries, connecting the positive terminal of the first battery to the negative terminal of the second. Link all the batteries in the same way, always joining opposite polarity terminals. You can stack cylindrical batteries, such as the A, C and D series batteries, on top of each other in a plastic or cardboard tube, or wrap them together in sticking tape. When using larger batteries with spring terminals, such as rectangular 6-volt batteries, join them with short lengths of wire.

Run a wire from the unused terminals at each end of the line of batteries. The voltage between the two wires is 12 volts.

First check what kind of lithium battery you have. There are major 2 type of lithium battery in the market. 3.7v cell and 3.2v cell. And find out the full charge voltage. If the cell is 3.7v. Nomally full charge voltage is 12.6v( 3S lithium ion battery. when fully charged, each cell 4.2 volt). While if it is 3.2v cell. When it fully charged, the voltage is 3.65 volt. 12 volt lithium battery pack fully charged is 14.6 volt.( 4S 3.2 v cell). Make sure your charger voltage is compatable with the 12v lithium battery.

Please note that not all Li-ion batteries charge to the voltage threshold of 4.20V/cell. Lithium iron phosphate typically charges to the cut-off voltage of 3.65V/cell and lithium-titanate to 2.85V/cell. Some Energy Cells may accept 4.30V/cell and higher. It is important to observe these voltage limits.

Important to Lithium battery chargers

Lithium cells (18650, lipos, LiFePo4 etc.) which require the charging cycle CC-CV (constant current, constant voltage). The battery system may work for other types for batteries as well, as long as they wants to be charged with CCCV.

CC-CV varies the voltage to constantly deliver the current set by you. When the voltage reaches the battery’s maximum charge voltage, the current is gradually decreased so that the voltage does not exceed the set value.
