Dc/dc 30Amp MPPT charge controller not accepting Victron IP-67 Smart Charger

I recently replaced my Noco 10Ah battery charger with a Blue Smart IP-67 12/25 Ah charger connected to a 50 & 140 Ah LiFepo4 battery wired in a parallel.
Since the new install my Renogy dc/dc Mppt 30Ah charge controller is giving me a red “battery overcharged” condition which I am not able to correct. My wiring is secure, and wondering if I need to change-out the charge controller or the IP-67. This is a new problem and my system was charging properly before I installed the Blue Smart charger, Any ideas appreciated.

  1. To help try and diagnose you could provide information on what voltage the Noco charged at and what you are now seeing and what the alarm setting is on the Renogy and what the battery manufacturer recommends.
  2. Did you choose the lithium mode on the IP67 when you set it up.

I will gather up that info and post on Fri, right now Im at my part time gig. I did choose the Li setting on the IP 67. Also didn’t know the Renogy had an alarm, defineitly will check into that one. Be real nice if it’s that simple. Thanks for the reply.
