RXV losing power with new batteries

Brand new batteries in RXV and cant get 18 holes in before cart dies. Batteries have been tested and all good there. Anyone else with similar problems/solutions?

How were the batteries tested?

What exact batteries? Not "they are 12v" or "they are 8v", more specific.

Crown 12 volt CR-GC150

You're sure they are all getting charged evenly?

Lack of range (Not travelling 18 holes on a single charge) indicates low storage capacity.

New batteries only have about 75% of their rated storage capacity until they are broken in, which takes a couple dozen charge cycles.

It is winter and for every 15°F below 80°F (Temperature batteries are rated at), the storage capacity is reduced by 10%.

Batteries have a huge thermal mass, so battery temperature is closer to the overnight low temperature than the daytime temperature on the course.

I suspect your 150AH battery pack has the performance equivalency of a 100AH battery pack, or less.
