The new electrical hydraulic system option is the old A109 electrical hydraulic pack so you will have hydraulic pressure
Even so..
I know of a pilot of a corporate 109A who parked it overnight at the boss's house.
Next morning he diligently commenced his preflight. Starting at the front he opened the battery compartment and pressed the two red buttons on the accumulators to check the levels.
The helicopter started to roll backwards down the slight slope.
He had to connect the battery, unlock the pilot's door, turn the battery and the bus switches on and get the accumulators charged before the helicopter ended up in the swimming pool that was at the bottom of the slope.
The whole lot stopped with the entire tailboom overhanging the pool and the main wheels just short of the edge.
This would have been avoided, as mentioned before, by using probably the one of the least technical devices in aviation.
Chocks.
