About this app

Do you build, repair / modernize toys, power tools or e-bikes, electric cars? You need stable power for your projects.
The application makes it easier (for DIY enthusiasts and electronics professionals) to calculate the parameters of lithium-ion or other battery packs.

App quickly calculate (for battery package):
- voltage [V]
- capacity [mAh]
- weight [kg]
- maximum continuous discharge current [A]
- Energy [Wh]
- qty
- battery pack price and price per 1 Wh (if you specify price per cell)

Calculator of the estimated working time of a device powered by a battery.

Built-in base 52 (popular, branded, mainly: 18650) batteries + possibility to enter parameters of your own (custom) battery.
You can modify existing and add new batteries in the database.

The database contains information about batteries, e.g.: LG (LG18650MJ1, LG18650HB6), Panasonic (NCR18650B, NCR18650PF), Samsung (INR18650-15Q, INR18650-25R), Sanyo (NCR18650BL, NCR20700B), Sony (US18650V3, US18650VTC5)

The application allows you to calculate battery packs up to 9999S 9999P - almost 100 millions batteries :) What will allow you to calculate packages for electric bikes and such large packages as for electric cars (EV).

Our battery (li-ion, li-po) calculator help you build battery pack as safe and efficient power source for your diy project such as RC modeling, flashlights and other hobbies.
You can calulate different battery sizes using custom defined parameters for battery cells.

Ratings and reviews

Great app! It has a lot of common cell types predefined. But you can also add new ones yourself, as custom cell types. Very handy! Kudos to the developer! I suggest to allow saving battery configurations that are built on the cell types. Also add saving the load configurations. You should also add fields for the cell dimensions, impedance, min&max Voltage, absolute min&max Voltage, etc.

Tried a few different battery apps this has got to be best one I have used. Needs more battery types and makes added like 26650s. Good thing is you can add batteries not in the list. Only downfall is that you can not save battery information that you enter and it be a great idea if there was some form of data base or updates were people share battery information because there are 1000s of batteries. Custom battery data can't be saved

The app itself is brilliant very well sort out extremely handy and easy-to-use and not bombarded with hundreds of ads. I give 100% for everything else honestly I do. but if I had to be a Critic I would say it would be great to see some more battery types, example car batteries, scooter, 6 volt ,12 volt up to possibly 24volt, deep-cycle, AMG. It would come in extremely handy for some people especially myself right now😁. Thanks for all your hard work. keep it up, it's appreciated.
