Description
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)

Comments on Battery Pack Calculator - DIY for Android
★★★★★Stephen Burger· May 5, 2026
It's truly the best app ever created it does every bit of math for you in seconds watts amps voltage and how long a battery would run for using what ever motor wattage you can input! The really cool thing is you can slide on a scale from literally 1 to infinity on both parallel and in serious and input your voltage draw and in seconds figure out the best combo for the e bike, scooter jumper box, car, truck, semi truck, boat plane or solar battery you want to build!

Does exactly what I need to calculate a custom 48v ebike battery with 5600 mAH 21700 cells. Easy and intuitive to navigate.
