With only 1 lithium charger, a small inverter, and old 250 watt restive load cycling 4 new batteries is time intensive.
The according to the BMS's the load is 212 watts, could be it's over 50 years old. The battery charger is a Schumacher SC1654. Higest voltage seen is 14.02 near end of charge cycle. Highest amps 28. Thats the background info. Current and voltage measurement verified with a Klein clamp on and Southwire DVM.
The AOLITHIUM app, not the best. App has to be closed and restarted to see a different battery. It only shows Ah, watts, temperature in C, and high, low, and average cell voltage. The high and low has to be interpreted from a graph.
Liontron app gives better information, but is confused by 4 batteries with the same device name.
Overkill Solar app displays the best info on 1 screen, allows changing the device name and other information. Be careful with this one. It is the easiest app to change which battery you want to look at.
Once the device name is changed Liontron now shows 4 unlabeled batteries. The AOLITHIUM app nows device new device name and as before shows the Bluetooth id for that battery.
The batteries were at 27 to 30% soc and with the charger take about 6+ hours to charge.
The load I have takes about the same time to discharge to 30%.
Customer service is great through Amazon, usually 12 hour turn around. Initially I was unable to connect to any battery Bluetooth, that was fixed by deleting the app and doing a hard shut down. That was also Customer service suggestion and it that didn't fix pull the battery cover and for the blue light on the Bluetooth.
Charge/discharge cycles continue at this time and cell balance is under 10 mV. 1 cell in one of the batteries went into high alarm and shut down charging. Nice to know that works.
Batteries came individually packaged and arrived in good shape. 1 box showed indication of being dropped on the corner but the internal closed packaging did its job.
At the present time when I get done with the cycles I may leave fully charged until they are put in service in April. Not sure why one would store at 50% when my Jackery power station instructions say keep it fully charged and recharge every 6 months.
