LiFePo4 Batteries Discharging Unevenly? 0 ▲ Marine How To 6 hours ago · Tech · hide In this video I go over a “feature” called OCP/FCP. This “feature” I first discovered on Epoch 460Ah V1 batteries.

In this video I explain what it is and how you can work around it. OCP = Over Charge Protection FCP = Full Charge Protection PLEASE HELP! This site is 100% reader supported. My wife is urging me to shut it down as it just keeps costing us money. My stroke-recovery, PT & OT is very costly & not covered by insurance as is authoring this site and keeping it secure.
