“Batteries 51V / 105Ah ECO Lithium Battery”

Only Epic name the pack by voltage and capacity and not by part number, and Eco Battery publish two batteries at those figures. Both are shown because nothing Epic publish says which, and the two do not fit the same tray: one is a squat block, the other long and shallow. Measure the battery bay before ordering either. Epic's own data sheets, last revised 19 July 2023, give the battery as 48-volt sealed lead-acid instead — the shop page is the newer of the two and this row follows it. Check yours before buying.

Not established: Epic name the battery's figures and its maker but not which of that maker's two 51-volt 105 amp-hour cases goes in. One is a squat block and the other long and shallow, so which one a given cart takes depends on its battery bay — and the bay has to be measured before either is ordered. That is a fitting question rather than an electrical one: both packs are the same voltage, capacity and chemistry.

This is the Thru-Hole, a squat block at 13.14 x 12.24 x 10.15 inches and 98 lb. Epic do not name Eco Battery on their own pages — they write “ECO Lithium Battery” and leave it there. ICON name them outright and name Epic in the same sentence: “all ICON EV and EPIC Carts feature industry-leading Eco Battery lithium batteries”. Epic fit ICON's motor and ICON's charger, and the two firms publish the same telephone number.
