I purchased two trays for my 150ah 12v group 31 batteries. I had a tight fit, but I really like the quality of these trays. Make sure you have room to square up the top and bottoms. The batteries are a perfect fit.
Love these products. I got a renogy 200ah, a Litime 300ah, and 3 Litime 100ah for front trolling position. As it turns out, the group 31 battery frame holds those 3 100ah batteries perfectly! So now I'm going to buy another battery frame for my 200ah!
This 36v battery is the best I've seen. Has Bluetooth connectivity to monitor. I ran the troll about 11 hrs my last trip and still had more than 70% life left. Highly recommend you make the switch!!!
The Abyss Battery trays are easy to mount and securely hold the battery in place. Best option I've seen for securing batteries in a fishing boat.
This review is for an abyss 36 V 72 amp hour lithium battery. Installation was a breeze very secure, clean and allows the battery. Plenty of airflow for cooling highly recommend!
