7 months ago I purchased this battery. I have not yet put it under a load. https://www.us.sokbattery.com/product-page/12v-206ah-lifepo4-lithium-iron-phosphate-battery-pack 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? 13.6 100% 13.4 99% 13.3 90% 13.2 70% 13.1 40% 13.0 30% 12.9 20% 12.0 9% Thank you.

Can anyone show me the ideal settings for charging the SK12V206 using a Victron IP22 120 Also is this one of the best chargers to use or at least an OK charger to use? tx
