HI!
I am needing to replace the battery on a Michael Blast Greaser Classic e-bike and am having trouble finding a replacement. Currently it has a Turn Life Li-ion battery; TL-48v14Ah-S; 672Wh. I have tried getting a hold of the manufacturer and no luck, hoping someone knows of an after market battery that would work. Thanks.

The chance of finding a battery with exactly the same connector and mounting method is about zero.
If you can get into the bike wire harness and cut off the connector, some generic 48 v battery could be used. My lunabikes battery came with XT90 connectors, but I was unable to solder on a mating connector that would not melt or fall off. I cut the XT90 off and crimped on dorman insulated .250 flag terminals. Female for plus, male for minus. For sale at oreilly auto supply. Pull test after installation. I find generic crimp tools make **** crimps. I use a Klein or Ideal tool. 6 years later, no more connection problems.
I encased my battery in a cage of 3/4" aluminum angle, inside a bag of packing foam, with a pvc bag top. Wires point down coming out of the hole in the bag, to form a drip loop. Battery cage is supported by 6 mm holes in my frame for a front basket. So weird, wannebe thieves have loosened some screws as I was shopping, but never the right ones. I use elastic stop nuts from mcmaster.com, stainless ones.
 
It looks like pretty much a standard down tube mount battery, as such I would look for a similar sized battery in that voltage and capacity along with its mounting cradle. Mount and wire up the new cradle, install battery. Depending on how the battery sits on the bike that should work for a non proprietary electrical system.
 
I agree. It's a typical downtube battery. If you had provided a detail picture of the cradle, a match could be found.

If the cradle doesn't contain the controller, and you no longer need to use the original battery, then gromike's suggestion of replacing both is the easy solution.
