Lithionics Battery Firmware Update

[Snackchaser]

If you have Lithionics batteries, you should check their Firmware.  Mine was three versions outdated!  The latest version of Firmware includes upgrades and corrections to the Battery Management System (BMS) and State Of Charge (SOC) accuracy.

The Firmware can be checked and updated with the Lithionics Application.  Go to settings and pick “Firmware Update.”  Then press the “Flash Firmware” button if you don't have the latest version.  Be sure to up-date each battery.

These Lithionics batteries are really top drawer, and priced to boot 😅I happened to come across a video yesterday showing why

Generic Brand X: Typical cylindrical cell. Lots of plastic, zip tied and a BMS bolted on. 

Problem: Many weld points, many cells which need to be leveled, plastic construction can have heat issues and doesn't conduct heat. Glued tinker toy construction possibly more prone to issues in a trailer. 

Lithionics

Large pouch cells for higher energy density, fewer welds and leveling. Aluminum for head conduction, integrated BMS which per OP has an app and firmware updates. Also they test and there's a lower internal battery impedance. Not to mention extra features like built in heating pad and on/off/status switch

I like the Lithionics. Just updated mine. I do wish the app provided a change log to tell you what the version changes are.

Here are the release notes for the current version, didn't see anything about earlier versions.  Probably only meaningful to techies:

Wow that’s a changelog! 

• Technical 
• Confusing user information, Neverdie cuts off at 10% so have remaining discharge time match, even though it still has reserve
  • After a week of rain and some vampires I left on I found my inverter off and the battery at 10%, but the lights and 12V still work. That’s NeverDie in action I believe saving the last 10% for emergency. If I’d check the remaining discharge it would have said 10% when due to this it’s zero (except the 12V appliances still work, so not sure the thinking here
• Algorithm calibration improvement
• Automatically recalibrate the usable power based on a calibration of actual performance - nice!
• Edge case if battery is powered off for a long time how some things are calculated 

previous releases are here

This one is from 2024 so looks like now they’re not updating too often
