Parallel vs Multistring WatchMonPlus

WatchMonPlus (WM5) allows connection to OEM batteries with balancing wires.  

Below is an example for a Tesla battery

When you have more than two modules it is possible to parallel the individual wires, hence modules.  

Caution should be exercised in doing this and get help if unsure what you are doing.

Our preferred method is wiring without paralleling but know that it can be done and has been done successfully although with the balancing power of the WatchMonPlus and extra complexity putting too many in parallel is definitely not recommended.

To solve this issue and allow multii-string with WatchMonPlus we are building a slave module multimon to add extra cell monitoring at a reasonable price.

See the typical wiring diagrams in related articles.
