Sure, if you planning on splitting the axle and running 2 motors ?
If not, you will experience some impressive understeer.
It wont matter if you are not worried about ultimate performance, but i can assure you it will handle poorly.
...... but with one 17kg pack on the left side of it, the steering is scary. It rails right handers nicely but pushes straight ahead in left handers. I
....that alone should give you a heads up as to what to expect.
The reason it pushes (understeers) in left handers, is because it cannot "jack" the weight off the left rear due to the extra pack weight out on that side pannier.
Vice versa on the RH corners where the pack weight is increasing the jacking effect.
Running both packs will improve the LH corners somewhat, but it will not be a balanced handling set up.
Ideally, any exta weight should be centrally located to minimise its effect on handling.
Remember , chassis flex depends largely on the all up weight it is carrying.
I was simply suggesting you may have to stiffen the chassis to compensate for the extra weight those batteries out on the panniers.
There are many kart classes that run twin motors, high power motors (100+ hp), and they all manage quite successfully with a solid axle and "weight jacking" to compensate, and chassis set up to suit the weight and power.
The "art" in kart set up is a fine balance between chassis stiffness (adjustable) , king pin inclination,(adjustable), front and rear track width adjustments ( adjustable) etc etc
Even seat position and location points are changed to suit track conditions.
OR.... Maybe this would be simpler....
