Why is my Charger Disconnecting on Connection/ at Beginning of Charge?

Problem

CV charger surpasses its current limit and stops charging during charge cycle.

Possible Cause

Chargers designed for constant voltage charging lead acid batteries were designed for a specific range of battery impedances. LFP cells have a much lower impedance than lead acid batteries, which can result in an inrush of current.

Solution

Reset the charger and try again.
