Broken / Melted Battery Terminal
02 DS IQ 48V Sepex cart
Went for a ride through the neighborhood today, and the cart just shut down and quit. Upon inspection I discovered the main pack positive battery terminal basically got so hot, the lead on the terminal melted and the positive bolt came out of it. The main positive wire to/from the solenoid was very hot, but otherwise, ok. See attached pics. Any ideas what may have caused this, and is there anyway to salvage the battery ? I really hate to buy 6 new batteries because of one losing its terminal bolt. The pack is still in good shape. Thanks for any help   Sent from my SM-N910V using Tapatalk |

Jdavila99999, you da man. Good video. Quick and simple repair and I'm 10-8 again. I'm just concerned about how hot the terminal got. I'll monitor the pack for awhile each time I go out

Re: Broken / Melted Battery Terminal
To me it looks like the battery terminal was over-tightened. That broke the bolt loose from its lead seat which caused a bad connection with produced the heat. Only tighten the lugs to 100 in/lbs of torque max.
