Simple installation, easy to use battery protector
July 24, 2016
no reason not to add balancing and over current protection. This module is low cost , pre set and works well.
Documentation is light, but adequate. only bug was no alert that if you connect battery , unit does not turn on until charging current applied(even for a couple of seconds)
  • Works well, easy install
  • documentation
