quick over view of my system.
2 packs each contains 2p16s 280a LFP. Total of 62 cells.
Each set has brand new JBD JBD-AP21S002 7-21S 300A BMS. Individually they work like a charm.
I have two bus bars way too oversized for this but when I parallel these BMS one doesn’t get charged only one does. Eg. If I turn the first one off the second starts to get charged fine. Turn the first one back on. It senses the other BMS and it won’t get charged. It shows everything fine but won’t charge or discharge as long as the other BMS is doing something.
I can’t comprehend what is going on here. I am trying to balance and match the packs voltage one pack is 56.7 and the other is 56.8. Can that be the issue ?
Got these BMS from batteryhookup.
thank you so much for all the awesome things you guys do.
