To my mind, the most logical way to go for those using a Shorai lithium battery is to use Shorai’s own battery management system; the battery and charger were designed to operate together - no brainer really (if you can stomach the cost).
On ‘store‘ battery voltage is dropped to 80% and returned to that level If it drops to 60% over time - apparently the best way to manage lithium batteries. Hit ‘charge’ before a ride and ‘store’ afterwards - rinse and repeat. The front of the charger describes the parasitic loss situation the 961 suffers from. Not saying that this is the only way to go, just that it has proven very successful for me.
That said, this suits the way that I use the bike. 200-250km Sunday morning thrashes around the hinterland near my home. This may not suit others that are touring depending on the extent of the parasitic loss, although the unit is not too large and is very lightweight so could be carried easily enough. My thoughts only.
