-Use the //VE.Can to CAN-bus BMS type B Cable//, part number ASS030720018. Plug the side which is labeled Battery BMS into the Pylontech CAN port. Plug the side labeled Victron VE.Can into the [[venus-os:start|Venus-device]].
+You can connect multiple battery modules together to form a single large battery by connecting the RJ-45 cable supplied by Pylontech using the link ports on the battery. This is shown in more detail in the  [[https://www.victronenergy.com/live/drafts:pylontest#example_wiring_diagram|example wiring diagram]] and Pylontech manual.
+The batteries will automatically detect and link to each other, no adjustment of dip switches or software changes are necessary on the batteries.
+The battery with the empty link port 0 is the master battery. Using the //VE.Can to CAN-bus BMS type B Cable//, part number ASS030720018, Plug the side which is labeled Battery BMS into the Pylontech CAN port of the master battery. Plug the side labeled Victron VE.Can into the [[venus-os:start|Venus-device]].
 Then, plug a [[https://www.victronenergy.com/accessories/ve-can-rj45-terminator|VE.Can terminator]] in the other VE.Can socket on the [[venus-os:start|Venus-device]]. Two VE.Can terminators are included with the package of the [[venus-os:start|Venus-device]] as an accessory, only one is used. Keep the other one as a spare.

+Without properly connecting this cable, the battery will not show up on the display of the [[venus-os:start|Venus-device]]. The battery will also turn itself off.
 It is important to ensure this connection and display of the battery on the [[venus-os:start|Venus-device]] display before attempting firmware updates or settings changes on other devices if they depend on the power supply from the battery. Without this connection, the battery may turn off unexpectedly.

 Check the Max Charge Voltage parameter. This voltage parameter is sent, together with the other three parameters,  by the Pylontech system via the CAN-bus cable. They are visible on the [[venus-os:start|Venus-device]]: Device List -> Pylontech battery -> Parameters menu.
+===== 9. FAQ =====
+**The maximum charge and discharge current is limited to 25A, but the data sheet tells me the maximum is 100A.**
+The maximum current is limited to keep the battery healthy and reach the 10 year guarantee. In off-grid, the inverter can draw more than the 25A limit to run the loads, make sure you have sufficient batteries installed to keep the load per battery around this limit.
+**After charging the battery the charge current often changes between 0A and 25A.**
+This is caused by cell balancing inside the battery. This happens with new batteries and after a deep discharge.
