see if an Earth-X is available in smallest size that fits your battery tray. cooling space is not necessary unless there's some special reason it's needed.
most applications require enough AH to support a starter... an 8 cell 26650 A123 battery would be 4.6AH actual and weight 24oz or closer to your original 2lb 8oz PB battery.
