Heyya! More product specifications are live : )

The moment has come!!!!!! Check out the top of the page : )

Completely agree with Toms - this was genuinely a great nudge in the right direction. A well-designed battery helper could save newcomers (and honestly, plenty of experienced pilots too) from a lot of uncertainty.

We’ll make sure the tool covers the points you mentioned: recommended charge/storage rates, IR expectations by cell type, and safe ranges for aging packs.
Additional things we’ve already thought about including:

  * Nominal, storage, minimum, and maximum voltages per cell

  * Safe discharge current estimates (C-rate calculation)

  * Puffing indicators and when a pack should be retired

  * How temperature affects charging and performance

  * Charging safety tips (Lipo bags, fireproof surfaces, what not to do)

  * Cycle tracking (rough life expectancy for different chemistries — LiPo, HV, LiIon)

  * Balance lead & main lead health checks

  * Signs of internal damage after a crash

  * Charging warnings (e.g., never charge above X voltage per cell, avoid fast-charging if IR is high)

  * Expected flight times for different quad sizes with that battery

  * Storage tips (humidity, temperature, how long they can sit at 100% safely)

  * How IR changes with temperature and age

  * Safe disposal guidelines

Basically, something that takes away the “am I doing this right?” feeling we all had at the start - and sometimes still do.

I’d start by re-flashing the SD card with a fresh OS. If that doesn’t help, switch to a different card - SD cards can get flaky with long-term use, and this one might just be a dud.

Ideally, you should keep your batteries in a LiPo safety bag/pouch - both during charging and during storage. These bags are inexpensive, usually around 10–15 “freedom dollars,” and they significantly reduce risk.

Over 95% of spontaneous LiPo fires occur during charging or after a hard crash where the pack has visible damage or deformation. Because of that, you should inspect each battery before every flight, right before plugging it into the drone, after every flight, and before and after every recharge to check for puffing or other abnormalities.

For extra safety, regularly measure the internal resistance (IR) of each cell using a charger or multimeter capable of IR testing. As a rule of thumb:

10–15 mΩ - healthy

15–20 mΩ - aging

20+ mΩ - danger zone (faster voltage sag, excess heat, higher puffing risk)

If a pack or a specific cell shows elevated IR or visible damage, retire it immediately or clearly mark it as “not for drone use.”
