Manufacturer documentation explicitly identifies this as compatible.
“Fits but will require upgraded controller and/or motor”
Only an Express that left the factory with lead-acid batteries — check yours before buying.
Fits only if the cart is modified. Eco say this pack fits but needs an upgraded controller and/or motor; the chart does not say which. The pack is 70.4 volts and these carts leave the factory at 36 or 48 volts, so fitting it raises the cart's system voltage — a conversion, not a replacement.
Not established: whether the pack fits this cart's battery bay without trimming, and what the charger must be. The chart gives a verdict per cart and no dimensions.
Eco Battery's own compatibility chart: under “EXPRESS” Eco mark the 70V 105Ah yellow: “Fits but will require upgraded controller and/or motor”. Eco's chart is for carts that left the factory with lead-acid batteries.
