@Todd I’m a bit concerned with all the places in the battery module case where the lithium battery bags are exposed. I’ve found little rocks and other large things in my battery compartment which would probably eventually puncture a battery bag over time.
I also see one of your battery modules which doesn’t look good and for some reason there’s a different sized space next to that module and the next.
I’m also wondering what you used for end caps to keep the modules from bulging/expanding when charging?
The one module was damaged in shipping, I’ve never got any debris in the front battery compartment. I used the factory Leaf end caps with 4 drill rods threaded at each end for the nuts that retain the steel end caps.
The bms outputs 60v on the charge port to operate a relay. You can use a 60v relay or a dc to dc converter to change voltage.
I also make an open collector interface that connects to white wire of DQ charger.
This will open the white wire circuit disabling charger.
Todd , those are way too high . Max voltage is 4.2v , but that will shorten their life span quickly . you should max charge to 4.0v .Those at at 4.4v are already stressed . you have to get your max voltages down or you will lose capacity . I went thru this with leaf cells and ruined a pack charging to 4.12v per cell .
So to use your open collector interface, the jumper is removed from the DQ plug and the lead from the collector is inserted into the wht wire’s terminal.
Do you want me to PP $25 to your account, or is there shipping on top of that? Is it a problem if I add 4 or 5’ to the wht it wire? My BMS is under the hood and the DQ is under the seat.
