We also use ICT and have been running them with both ISP Supplies and Power Storage Solutions LFP packs without any problems. The only downside is that the ICT shelf can't read the state of charge or give your an estimated runtime remaining with lithium batteries. I understand they won't have a super accurate reading on those parameters without communicating with the BMS, but I wish they could at least calculate AH in and out vs set AH capacity to give a rough estimate.
