 TAB has undertaken full Victron BMS-Can specification compliance testing and has successfully passed.
-Testing was completed with TAB e.module L5.1 running BMS firmware version 0.3.4-8
+Testing was completed with TAB e.module L5.1 running BMS firmware version 0.3.5 and Cerbo GX running VenusOS v3.63

 It is essential to use the BMS-Can (or CAN-bus) connection of a [[venus-os:start|GX device]] with these batteries for communication of charge and discharge limits, error codes and state of charge.  This is set to 500 kbit/s.
-It is recommended to use the latest firmware version on new installations and when trouble shooting issues.

 Victron BMS cable type A or B can be used to connect between the TAB COM port and the GX device.

 Once the communication is established: If the battery doesn’t receive any communications from the GX device for 30 minutes it will shut down.
-At 3.60V cell voltage battery will trigger a warning, at 3.70V battery will disable charging. If the battery is overcharged, only the module with overcharged cells will isolate charging mosfets and stop charging, other modules can still charge, but CCL will be 0. The system can normally discharge.

 Some of our Solar Chargers feature a VE.Direct communication port, some feature a VE.Can communication port, and some feature both. Both of these types of communication ports can be used to connect the Solar charger to the GX Device. Such connection is mandatory, because it is used to regulate charge currents and voltages.
-When planning to use the VE.Can communications port to connect the Solar Charger(s), make sure to select a GX Device that has sufficient CAN-Bus ports. The Color Control GX has only one such port, its VE.Can port, and is therefor not suitable. All other GX Devices can be used, since they have two ports. One can then be used to connect the BMS-Can battery, and the other to connect the VE.Can Solar Charger.
