I have a new load tester since the CHINS batteries. After I was done with 31A load, I swapped with my old load tester @ 15A to test the BMS. With my multimeter connected, it tripped at 10.7V. Ampere Time's specs are 10.8V. The battery is now charging again with the PowerMaxx charger. I didn't really want to post everything like I did with the first two batteries. I though that if anything went wrong, I would post that. Just don't want to repeat and bore everyone.
Also, I like to end my load tests with 11V and see what the capacity is. After 11V, the voltage drops so fast, it will not make a significant difference. My batteries surpassed their capacity with 11V, that makes me happy. I have read in many places that doing a complete 100% discharge will shorten the cycle life as opposed to an 80% discharge. So, 11V is my personal limit. Not 100%, but close. I have relays installed on all my builds with 100A to cut power at 11V. The relays are limited to 100A. I use the together with Thronwave's smart shunt. Unfortunately they will not work with these Ampere TIme batteries which are capable of 200A. But that is OK. No need, my Growatt will allow me to set all of these parameters anyway.
Very cool, appreciate the tests, info and clarification.
