User Reviews

Users praise Battery Pack Calculator as easy-to-use and clean with a practical focus on DIY battery packs. It provides quick, accurate calculations for size, amps, series/parallel arrangements, and watt-hours, and hosts a broad library of common Li-ion cells. Many users report it’s reliable and does exactly what they need. Common drawbacks center on an outdated database that lacks newer battery models, and requests for additional features such as charger-time estimates and LiFePO4/LiPo support. Overall, it's a handy, developer-friendly calculator that excels for basic designs but could be expanded with more chemistries and charging insights.

Pros

Easy to use and intuitive interface
Provides quick, accurate battery-pack calculations (size, amps, series/parallel, watt-hours)
Large library of common Li-ion cells for reference
Reliable and does exactly what users need
Very helpful for DIY battery pack design

Cons

Outdated database; newer battery models not included
Lacks charger-time estimates and charging calculations
Missing LiFePO4/LiPo (lithium phosphate) battery support
Could benefit from additional features and improvements

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!
