I have other hobbies that use Lithium Polymer 3s batteries both 250 size drones & rc trucks ,...My understanding, with Lithium Polymer batteries is that is unhealthy for them to be stored , or remain for a period of time in either a fully charged , or fully discharged state , a "storage charge" of around 40% is recommended , I only charge them when I intend to use them ,.& then only discharge them down to a safe level (as determined by cell count ,mAH etc) & use balance charge to ensure cells are even ,..I charge these in a fire resistant ammo can & monitor the charge cycle , I store them in a fridge at storage charge when not in use , to keep them " dormant" Now I dont know if Lithium Ion is the same thing or not ,Not sure what the SDS uses or how many cells ,..but if it is LiPo I hope the smart charger firmware can accurately determine cell count ,..mAh , voltage & charge at a rate that will not damage the battery or reduce its lifespan or capacity & that during running, the Low Voltage Cutoff can be set or detected correctly , Lipo batteries can be a potential fire hazard if you do not understand how to charge & store them ,..I always try to charge my rc batteries at the slowest rate ,.unless in some sort of emergency rush , I dont wish to put the wear of excessive heat on the battery from the fast charging
