Anything in particular you need? Or features you require?
Current Connected has my recommendation.

Bro you need to tell us the application of this 48V battery

Just home backup power to compliment what I already have. I currently have two 12v 200ah batteries and am moving to 48v. The batteries will be used to power up variety of stuff via inverter.

Just look at your electricity bill and you will know how large the battery you will need. If you just want a mid range battery, rack battery might be a good option. They are not of good looking but more cost effective. The smallest one in the market together with good looking is 51.2V 50ah 2.56kwh or 51.2V 100Ah 5.12kwh wall mounted one. If the design is not something you care about, then go to stack on or rack one. The capacity can go from 10kwh to 20kwh. Just choose whatever suitable for you.

There is kWh per day,
kW continuous load,
kW peak load starting motors.
The batteries will have similar specs, but in the form Ah, A continuous, A max for a limited time.
You will need some number of batteries to supply the kWh per day, but possibly a larger number for the starting surge of something like an A/C or pump.
When you connect a lithium battery to an inverter, especially a several kW inverter, for a moment the input capacitors look like a short circuit and it draws thousands of amps - way more than battery's BMS wants. This can cause battery to shut off, or for fuses to blow. To avoid that use a precharge resistor.
