“BATTERY: ECO 51.2 Volt 105Ah Lithium Battery Pack”
Only one of Eco Battery's two 51.2V 105Ah packs — Advanced EV do not say which — check yours before buying.
Fits as it is.
Advanced EV name the pack maker, the voltage and the capacity in this model's own panel, and Eco Battery make TWO packs answering to it — a Thru-Hole and a Skinny. Advanced EV do not say which case, so both are recorded, neither is presented as the one fitted, and the case in the bay is worth checking before ordering. Source: https://www.advancedev.com/advent
