I suspect that more information regarding the length of overhang between the rear wheels and the proposed location, the overall size and weight of the bus, whether it is rear, front or mid engine, etc. is required.
All of these parameters regarding weight distribution would influence such a decision.

I plan to use 4 AGM's with a total weight of about 140kg..

would I be putting to much weight towards the back of the bus, or should I have them closer to the Rear Wheels..?

So Tail of the bus..?

close to the Rear Axle..?

or between both axles..?

 As would the dimensions of the batteries and the space available to put them..
We mostly mount stuff in the only suitable place for it ..

Ok Planed bus is a Coaster.. LWB [B50 model]

Kerb weight of 3.1 to 3.5t
Wheel base of 3.9m
Rear over hang unknown..

Battery dimensions

- Term H - 272mm
- Length - 262mm
- width - 181mm

Most likely configuration at this stage is 2x2
so 262 +262 [Plus Gap] = 524mm+ for length
181+181[Plus Gap] = 362mm+ for width..

Hope this helps you..

 So when you have the bus you will be able to look at all the locations available to you to put them and all the other things you want to have on or in it..

I think you are trying to cross too many bridges before you come to them..

Maybe with all the things you are looking at having you need to buy a 12mtr double decker bus and get a licence to drive it..
