I have just finished putting together two 12V x 280AH LifeP04 battery packs using JBD-SP04S020 BMS's and the charge and discharge currents are way off. Paid the $10 for the Xiaxiang BMS app and run the idle, charge and discharge calibrations. Measurements changed but are way off. They are in parallel and at the moment my Victron shunt shows 48a going in but the BMS app is showing 5.8a on each battery. Saw pretty much the same when I checked it while discharging. Any suggestions and what the issue might be.
