CellBoss Get told when it’s out

For JBD boards

A clean app for JBD boards, instead of Xiaoxiang

JBD boards are inside many drop-in 12 V lithium batteries: the ones that replace a lead-acid battery in a caravan, a boat or a bakkie’s canopy. Their usual app is Xiaoxiang. CellBoss reads the same board and shows what matters on one screen, in plain words.

What CellBoss shows from a JBD board

  • The charge, the voltage, the current and the power, with the time to full or empty.
  • Every cell with its voltage, the lowest and highest marked, and how far apart they are.
  • Temperatures from the battery’s sensors.
  • The board’s protections in plain words, such as a cell too high or too cold to charge.
  • The charge and discharge switches, shown and never changed.
  • Charge left and cycles, from the board’s own count.

Why people look for a Xiaoxiang alternative

Xiaoxiang is built for setting a board up as much as for reading it. CellBoss is built for the everyday look: open it, see the battery, done.

  • Read-only: no settings, so nothing gets changed by accident.
  • No location permission: CellBoss pairs through Android’s own pairing screen.
  • No internet: it works at a campsite with no signal.
  • No ads, no account.

How to connect CellBoss to a JBD battery

  1. Close the Xiaoxiang app, or the battery maker’s own app. A board talks to one phone at a time.
  2. Open CellBoss near the battery and tap Pair a battery.
  3. Pick the battery in Android’s list. JBD boards often show the battery maker’s name rather than JBD.
  4. Name the battery and give its capacity.

Two batteries in the caravan?

With Pro, CellBoss adds batteries in parallel together in the bank view, and shows each one’s cells with a tap.

JBD BMS app questions

Is CellBoss made by JBD?

No. CellBoss is made by Kindly Made and isn’t affiliated with JBD or the Xiaoxiang app. It reads JBD boards over Bluetooth and never changes them.

My battery has its own brand’s app. Will CellBoss read it?

If there’s a JBD board inside with Bluetooth, usually yes. Many brands put a JBD board in their batteries and give the app their own name.

Can CellBoss change my JBD settings?

No. CellBoss is read-only. Use the board’s own app if you need to change a setting.

Does it need internet?

No. It reads the battery over Bluetooth and never goes online.
