About to pull the trigger on six 2kwh Samsung 8S modules for my 48V solar golf cart. Are 3.7V lithium NMC prismatic cells originally for a UPS. Will run two modules in series for 16S, then three pairs in parallel. Looks like they will comfortably fit under the seat.

Question #1: need to purchase three 50A 16S BMSs. Any recommendations for neophyte users? Daly seems to be a popular model. Bluethooth connectivity would be nice.

Question #2: My existing Delta-Q QuiQ will output around 58V in bulk mode, and my WZRELB inverter cannot handle over 60V. Not sure what the AC motor cart can handle. The Samsung 8S low voltage is 49.6V, and high voltage is 65.6V. Any downside to using my Delta-Q for charging? Understood will not be able to use the full module capacity.
