should be no problem! 100 amps enough unless your golf car oversized or overpowered or something. (100amp @ 48V = ~5000 watts power!) Fully charge all of them to 14.4V then wire in series and you'll charge the whole golf cart at 4x that so 57.6 volts. Congrats you have 16 cell lifepo4 battery with built in BMS in each bat. You'll need to find suitable chargers but they are available in these common voltage.

Extra credit: each battery has 4 lifepo4 cells. that charge to max 3.6 Volts. 3.6*16 = 57.6 V. Thats the same voltsge the BMS's stops charging at!

90 amp- hour * 4 * 12.8 volt = 4608 Watt-hr or 4.6 Kilowatt hours energy storage. thats good! for Reference a tesla has 65 KWhr capacity.

these are probably 100 ah cells that couldn't pass the capacity test. I wouldn't be surprise if they test very close to 100ah

They don't like the heat, they don't like the cold, and cannot provide the surge.

Stick to batteries intended for cars.
