Question about the Delta-Q charger

[Kingfish]

I have done a LiPo4 battery upgrade on my E1.  I have reprogrammed the charge profile to #386.  With the onboard BMS the controller cuts off all charge from the IC1200 when the battery reaches 100% to prevent overcharge.  When this happens the charger begins flashing the yellow light and displays the error code 013 which is telling me the battery is no longer accepting a charge input which is as it should be.  I hear a relay switching in and out every few seconds as the charger continues to try to reach the shutoff charge profile voltage.  My question is will it cause any harm to the IC1200 to stay in this state for hours or maybe even days if I don't get out to unplug it?  I used to leave the E1 plugged in all the time with the old Discover batteries.

In case anyone is interested, I heard back from CS.

Apologies for the confusion. Understood about your choice of algorithm. Just wanted to be sure that it is the BMS expected behavior to shut off charge input when it reaches 100% and not the overvoltage protection getting tripped. 
 
Some errors will completely disable the charger outputs and will only clear after an AC reset or a corrective action. However, with error E013, it seems that the DC output relay keeps switching in an attempt to push current to the batteries. Continuous relay switching can over time shorten its lifespan. While we don’t have specific data on how long the relay would last under these conditions, generally, reducing the number of this switching transitions would extend the relay’s lifespan. So, it's better to prevent this error condition in the first place.

Don't know if you resolved this, but when I did my conversion with ReLion batteries, they actually had a custom profile for the Delta-Q charger they sent me to upload into the charger. I don't know what brand you used, but maybe check with the battery maker technical support?

The battery manufacturer of mine say they have never heard of the Delta-Q charger.  I am no longer concerned about the charger going into E013.  DQ customer support said it will do no harm to the charger to sit that way for a while.  The onboard BMS stops all charge to the batteries so there is no danger of overcharge.  At some point I may try changing the algorithm to #133 and see what % the the batteries charge up to.  This would allow the charger to perform as before with the Discover batts. and stop the charging on its own.

There is a short to stop option that can be loaded , in the same was as adding an algorithm. This then uses the two Temp senor pins and when shorted starts the charger and when open, stops it. No power switching, no removal of load.
