I recommend enabling "CC" mode and playback a little faster. Source: I have three, significant LiON batteries: 44 kWh Tesla Model 3 - parked on unenclosed driveway, furtherest, 10 yards from the utility room 28 kWh BMW i3-REx - parked on unenclosed driveway about 4 ft from Tesla but about 2 yards from solar battery 13 kWh solar storage - mounted on shady side of exterior, brick kitchen wall near corner and 10 yards from utility room In addition to the utility room, there is a front and backyard exit from the house. IMHO, a reasonably safe layout. Battery placement needs careful attention and reasonable fire hazard judgements. Bob Wilson
