Question about the Delta-Q charger

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.

      Hisun Sector e1 Battery replacement: any tips?
      By didgeridoo
      Hello, All!  I've decided to replace the traction batteries in my 2018 Sector E1 with a 48V Lithium set. They may be expensive, but I figure the Discovery Dry Cell are, too. I am not looking for the max driving range, as I have never received near the brochured range to begin with, but a good mix of charge/ get work done/ charge is what I am expecting.
      I have settled on the 48V EAGL kit from bigbattery dot com. Each battery pack provides 30Ah. The kit ships with a charger, as well. The packs would be physically connected in parallel (using a busbar) to one another, maintaining the 48V voltage, but together would be able to provide the amp draw the buggy pulls when going up hill or towing a rake (rated 320 max continuous Amps). This is in comparison to the serial connection the eight 6V lead batteries. Each of the EAGL batteries looks to have its own BMS; am I correct in thinking I will have to use their included charger rather than (simply) changing the onboard charger to lithium mode? The chemistry of the pack is LiFe PO4, for what it's worth.  I haven't torn anything apart yet (to diagram), so  I am not sure how the dash will interpret the AMP draw, but the kit I am looking at includes a dash mounted charge indicator.
      If anyone has completed a similar conversion, do you have any tips? Specifically, how did you remove the original batteries, and how did you secure the new ones? I am guessing that almost any change from the stock batteries would involve at least some modifications. Any tips would be appreciated, especially things I may have failed to consider. Thanks!

      Battery Life
      By Gorj
      I am into five years of ownership of my electric side by side and I am noticing some deterioration of power. Although I measured the voltage at over 49 volts, I believe the batteries are beginning to fail. I charge them about twice a week. Last year the charger went out and I replaced it with a 48 volt golf cart charger.  What has been your experience with the batteries?

      BMS UTV sluggish acceleration issues/ final gear oil maintenance concerns
      By bms stallion owner
      hello, my BMS Stallion 600 is having accleration issues. the manual fails to show final gear oil diagrams very well... I have the owners manual and suspect issue is associated to transmission , I want to check the level of the gearoil. I located a drain plug (but not the fill plug nor dipstick). It will run - but wont exceede 2mph. Troubleshooting suggestions or comprehensive manual suggestions? Thanks

      Is there a better performing higher volume injector than what they come with or what is the best replacement for the original?

      I’m need a couple parts. Diff. Lock Actuator mainly. But I would like to find a donor that maybe has bad motor or something along those lines. 
      if anyone has or knows of anything please holler at me 
      thanks Randy
