Unable to cast value to Object?

im not good with remote events but i do know on :FireClient() the first parameter is always the player but if i leave it blank it says missing or nil and if i define the player it says unable to cast value to object any help?

--script
script.Parent.Touched:Connect(function(hit)
game.ReplicatedStorage.Battery:FireClient(hit.Parent.Name)
end)

--localscript
game.ReplicatedStorage.Battery.OnClientEvent:Connect(function(hit)
	hit.Backpack.Battery.Value = true
	print(hit.Name.."Has Picked Up Battery")
end)
