Description
Twice the M24 in a pack that still weighs 11.68 lb. It stores 640 Wh (our math: 12.8 V x 50 Ah).
Pro-Guide lists it for fish finders, kayaks, small marine electronics and light RV or solar setups. Max continuous draw is 50 A.
Charge it to 14.6 V (plus or minus 0.2 V), 10 A standard, 25 A max. The case is IP65 rated. Pro-Guide’s rating is 3,000 full (100%) discharge cycles, with 5 years of free replacement under warranty.
Good fit if: Your kayak or fish finder setup needs more than the M24 but has to stay light: 50 Ah at 11.68 lb.
Not the pick if: Your load pulls more than 50 A continuous: step up to the 24M100.
