Lithium-ion batteries are considered one of the safest battery packs.

Still, there are some low-occurring hazards in 12v lithium-ion battery packs.

Significant failures in 12v lithium-ion battery packs are due to the operation of batteries at high temperatures.

This occurs mostly due to manufacturers’ negligence, and you should make sure that your battery packs are tested right according to the international standard of testing.

When there is a failure due to extreme temperatures, failing cells due to high heat can also circulate in the next cells, resulting in instability in the next cells.

This result in a chain reaction between the cells, and this can destroy the whole battery packs within very little time

In order to prevent a chain reaction, the dividers are used to save the unstable cells from the stable ones.

Your 12v lithium-ion battery packs can get damage due to improper usage, and your battery packs can be damaged due to improper storage place.

Unsuitable charging and the discharging rate will also limit the battery life and durability.

In order to operate battery packs in safe conditions, you must make sure that your battery is incorporated with the proper battery management system.

It should be checked that your supplier has followed all of the required testings for the battery packs.

You should keep track of battery parameters by BMS and should consult the battery manual for any guidance.

It is preferred that you store the battery in a safe and appropriate place.

You should avoid using the battery in extreme conditions.

Some damages to the battery don’t happen spontaneously, but it occurs over the long span.

These damages can be due to no proper charging, operation of batteries in extreme conditions and temperatures.

If you are charging batteries at a very low temperature, then it could lead to permanent metallic lithium buildup on the anode side of the battery.

This will eventually lead to the failure of the battery packs.

You should consider manual instructions while charging the battery packs; otherwise, it could cause damage to cells of 12V lithium-ion battery packs.

It is preferred to use the manufacturer’s charger for the battery charging because it is manufactured according to battery specifications; if you are using any other charger, then it might cause an improper charging rate.

15. What size of cable should we use in the system of a 12v lithium-ion battery pack?

It depends on the number of factors.

Most importantly, it relies on the size of the load you are operating with.

Secondly, it also depends on the distance of the battery pack from the load.

For this, you might need voltage drop calculations for every cable size.

Please refer to a reference chart for cable size.

Figure 8 12-Volt Lithium-ion battery packs Reference chart for cable size

Figure 8 Reference chart for cable size

There are some general guidelines for the cable size as compare to load.

If you have a DC load of a maximum of 157 amperes, then you should use 4 AWG wire.

If you have a DC load of a maximum of 291 amperes, then you should use 1/0 AWT wire.

If you have a DC load of a maximum of 157 amperes, then you should use 4/0 AWT wire.

16. How should I know that my device is compatible with your 12v lithium-ion battery pack?

You should check the manual of your device and should check the parameter of the following settings.

You should check the bulk/absorb capacity of your device.

You should check the float range of your device.

Also, consider checking absorption time as well as temperature compensation.

It is also useful if you can get in touch with our technical heads, they can design battery packs right according to your device requirement.

You can use a series or parallel combination of 12v lithium-ion battery packs to adjust the battery’s voltage and capacity according to your requirements.

17. What is the rate of discharge and depth of discharge, and how does it affects the performance of 12v lithium-ion battery packs?

The rate of discharge for your 12v lithium-ion battery packs implies the speed under which your device is absorbing Power from the battery packs.

Usually, every battery pack has a different discharge rate, and they are designed according to your need.

If you discharge the battery in lower time than the mentioned time, then you will get lower energy from the battery

TLH 12v Lithium-ion battery packs will deliver optimum battery power even under a high discharge rate.

Depth of discharge is also known as DOD, and this is the amount of energy-driven out from the battery when the battery is in fully discharge condition.

Now the question arises how one should figure this out?

For example, you have a battery of 50 amp-hour, and you have discharged 25 amp-hours; this implies that the depth of discharge is 50%.

If you discharge 20% for the same battery, then your depth of discharge will be 20%.

You can discharge the battery to 100%, and there will be no long-term effects on battery performance and durability.

18. Can 12v lithium-ion battery packs withstand vibrations?

TLH battery packs went through various tests before they are manufactured.

We follow internation standards of testing for the production of 12v lithium-ion battery packs.

Our 12V battery packs have passed all of the international lithium-ion tests, and these tests include the following tests;

  • ISO 9001:2015
  • UN 2054
  • CE
  • UN 38.3
  • IEC 62133

You also need to check the base and connections of 12v lithium-ion battery packs, and you should have regular preventive maintenance to avoid any such issues for the battery packs.

19. How should I decide the dimensions of 12v lithium-ion battery packs for my system/device?

This is one of the essential things to consider.

It would help if you had the right information and calculations in order to get optimum results.

Firstly, you need to figure out the max amps and watts draw of your device.

You can get this information from the nameplate or manual of the device.

Here are the simple calculations for you, which will help you understand.

Consider a system of 120 volts with ten amps and a run time of 3.5 hours.

For power calculation, apply the formula of P=VI.

This will get you the Power of 1200 watts.

For the calculations of watt-hours, apply the formula of Power*time.

This will get you the energy of 4200 watt-hours.

For getting DC amp-hours, we will divide energy with 12volt, and this will give us a Direct Current of 100 amps.

Finally, we have the number of 100 amp-hour, we will build the battery according to this Direct current.
