I have a 2000 Triton TR 20 I have converted from 24 volt to 36 and used group 24 batteries, its time for new ones and the type I want I can only find in group 27 which are too long for my battery tray, I read somewhere to cut the end of the tray and use ratchet straps to secure them. Where would I attach the ratchet straps? The battery space is really tight and hard to reach. Thanks for any advice.
