Dear Sir or Madam,
We have found a bug in the firmware in the LiFePO4-Smart batteries. Due to this error they may stop working at some point. VictronConnect will show ‘Error: communication error’ in red.
The problem is solved with a firmware update, Smart Lithium v1.06.
All Smart Lithium batteries
First install VictronConnect, or when you already have it installed, make sure it is updated to v3.0. See the VictronConnect manual for details.
Then open VictronConnect and connect to the battery. It will then automatically install the firmware update in the battery.
Questions and answers
Q: Do all batteries, both shipped and in store need to be updated?
Q: What happens when the error arises?
A: All connected equipment (Multis, Solar chargers, Battery protects, etcetera) will switch off.
Q: Can a battery that already shows the failure be updated?
