  • V1 batteries are not compatible with V3 batteries.
  • V3 batteries can be installed on existing V2 systems, but full functionality is only guaranteed when all batteries are the same generation.
  • Heating is only available when both the master and slave batteries are V3. Heating function will not operate in mixed V2/V3 systems.
  • If mixing V2 and V3 in a single battery stack, a V3 master battery is recommended. If a V2 master battery is used, a firmware update to the master will be required.
  • V2 and V3 batteries cannot be mixed when using the BMS Parallel Box. Each parallel battery string must contain identical battery versions and quantities.
