What is the full voltage of a 11.1V lithium battery pack?

The full voltage of the 11.1V lithium battery pack is 12.6V, the nominal voltage of all 11.1V lithium battery packs on the market is 3.7V, the full charge voltage of a single cell is 4.2V, and the battery structure is all 3 strings connection, the calculation method of the fully charged voltage of the 11.1V lithium battery pack is as follows:

Nominal voltage: 3.7V * 3 =  11.1V

Full-charge voltage: 4.2V * 3 = 14.6V

How to make a lipo battery 11.1V?

  1. Cell preparation. We will evaluate the cell model including size, capacity, and voltage based on customer requests.
  2. Cell match. We shall check the voltage range, capacity range and resistance range. Must keep them at the minimal difference.
  3. Assembly. After soldering PCM protection board, we should keep it at specific size.
  4. Aging Test. Before deliver out, all batteries must do charge & discharge at 0.5C rate.

FAQ

How long do lipo batteries last?

The theoretical life of lithium iron phosphate battery is 500 charge-discharge cycles, that is, once a day, it can also last for more than 1 year.

Can you fully discharge a lipo battery?

Deep discharge and deep charge and shallow discharge and shallow charge have little difference in the impact of lithium battery life. In fact, shallow discharge and shallow charge are more beneficial for lithium polymer battery.

Is lipo battery better?

It supports to custom different size, shape, capacity. No smoking and fire case.

What's your main product line?

We mainly produce 3.7V, 7.4V, 11.1V, 14.8V lipo battery pack for different applicants. You can also get other custom lipo battery based on customer demand.

What's leadtime for lipo batteries?

We will deliver out withou 7~10 days. Within these days, we will do at least 1 cycle of charge & discharge. It will take 30 days or more for general order. We suggest that please allow give us a little more time for aging and cycle test. It benefits a lot.

How do I maintain my lithium polymer battery?

Less than 1 month: -20℃~+45℃; Less than 6 months:-10℃~+35℃

What They Say

We are happy to say that after our hard work and persistence, we have received praise from our customers, thank you for their support, and we will continue to work hard.

DB Technology works with some of the top brands around the world such as Bose, ZAGG, Victrola etc. We came to HLC with a very specific set of requirements needed to replace a defective battery from another “low cost” supplier. Henglichi not only met or exceeded all the specifications, including safety tests, they actually beat the previous vendors price!

DJ David
David B. James CEO

With this company, we’ve had no issues with quality, no issues with lead times and the engineering support has been excellent in designing and producing the needed battery solution for our customer’s needs. Even better, all testing services have worked perfectly to accommodate international sales with the required certifications.

Saili Development and Quality Manager

Just what I needed to replace my old batteries, these are good quality batteries with a high power rating. The batteries are working really well as none have yet run out of charge for what they are being used for. I bought over 30x batteries of this company for kids toys and hand held home items. Cheaper then branded batteries and works the same.
