3 off 5s 5000mah 25c lipos and a charger will give 100 amps discharge capacity. charge each lipo separately to recharge them.
THESE ARE SERIOUS BATTERIES BUT STORE IN A DRY PLACE AND CHARGE IN A FIREPROOF BAG .
BTW A 4S 5AH ONE WILL START A CAR .

It's really great to receive replies, with useful, intelligent information.
But one wonders sometimes, just how do I use it. What does it mean?
Enter, the learning curve.
I'm taking
this suggestion, as it applies to the final battery purchase, not the temporary bats needed for testing.
The Nissan Leaf vs alternative choices. Am I right?
After a bit of checking this, and checking that, I have this question.
These batteries look so small. And much of their use seems to be for RC vehicles, not full grown vehicles..
As I understand the spec of the motors....each motor pulls 32 amps.
Two motors, and the load current stays at 32 amps?, .... or is it doubled?
The battery your suggesting, ( I did go looking for it ), has a discharge rate of 100 amps.
(100 - 32 = 68 amps in reserve ?) ( OR is it 100 - 64 = 37 amps in reserve?) ...Or D, none of the above
The answer could save me a ton of money.
Why not scrounge, purloin, steal (probably not a good idea), borrow, or otherwise obtain, get 4 a 12V car batteries and put them in series? That will give you 48V, near enough to 50V.They are used at well over 50 amps every time they start a car engine and they do that plenty of times during their life. The short term load kicking off your 2 x 1800W motors and ticking them over under light or nil load, shouldn't even make them blush. That should enable you to test your wiring, etc.
By the way, if you want to easily understand this secret electronics stuff, go to:

Yes the 4 x 12 volt batteries in series, is how this conversation started. But there is the issue of how high the amp hours need to be, for this particular, intermittent use.
