+==== charge-and-stop ====
+Charge-and-stop usually charges to 14.2v or 14.4v then stops until nank voltage drops to 13.2v before restarting Bulk charging. This occurs because charge-and-stop does not use a Float setpoint.((Li doesn't need Floating in the lead-acid sense, but [[opinion:frater_secessus:electrical:12v:drop-in_lifepo4#mythyou_shouldn_t_float_lithium|it can still be useful]].))
+Under very light loads this would result in cycling between 90% and 100% state of charge.  Because of [[electrical:12v:voltage_sag|voltage sag]] heavy loads might result in cycling between 95% - 100%.
+If this is undesirable behavior you can set up a USER profile with whatever setpoints you wish ([[electrical:12v:drop-in_lifepo4#mythyou_can_t_charge_li_with_a_lead_battery_charger|suggested settings]]).
