JTAS 3 is quite clear: it says “energy storage system” – so I’ve presumed a stonking battery. Although perhaps “one” under the floor plates of

the ATV and spread out (a bit like HMS Alliance, a WWII submarine you can visit about five miles from my home).

Well, you'd still want it to be easily replaceable. But having individual cells scattered around the lower chassis could make sense. It would help keep weight distribution on different wheels more even (batteries are heavy) and it would help keep weight on the low side (less rollover risk) and it would make them potentially accessible from the outside (may have to remove a wheel & rim or something). Separate cells might fail out at differing rates which means you could do piece-wise replacement rather than replacing one expensive battery (Ford Escape Hybrid - $7K US for a replacement battery, lifespan 7 years about).
