After charging my battery yesterday, when I came to go for a ride today the lcd display said the battery was half empty. When plugging the charger in again, it went straight to green. Checking the battery with a voltmeter it reads 36.9v so I guess the display was correct. What should I check next? Battery and charger are both only 6 weeks or so old and have been ok until now. Probably used about 10 times.

All you can do is check the charger voltage output reads 42v, being a soft pack it will have to go back to Enerpower.
Any thing else will invalidate warranty so you will have to speak/contact them.
If charger voltage is ok then the battery is at fault, could be a wiring issue, low cell group or bms issue.

Measure the voltage on the battery's charge socket too. It should be the same as the output voltage. Be careful not to short it when measuring.
