7 months ago I purchased this battery.
I have not yet put it under a load.
1) Is the Bluetooth module available to install on the battery I purchased?
2) When I received my battery the voltage was 13.07 V
For long term storage of 6-12 months with little use what voltage should I try to start the battery out at and keep it at?
3) I purchased the IP22 Victron Energy charger.
Using the Lion setting it switches from Bulk to ABS at 13.1 volts and the battery never goes above 13.2 V even after hours of charging.
is this normal?
4) Can we get any idea of state of charge from the voltage reading?
I found this chart. Are these voltage readings an approximate indication of SOC?
