TL:DR nerf power draw please.
On my ZH Mobility frame, idling with temp set to 50, and liquid cooling, I use up half my charge in about 15 minutes. Moving only changes it to about 13 minutes.
Sprinting, with temp set to 20, took me about 3 minutes to drain half my charge.
Or, to put it another way, it would take me about 26-30 minutes to drain my battery from full to zero at my most conservative activity (ie no running around). Sprinting will basically drain my battery in minutes.
Additionally, the cooling system can't keep up with the suit cooler in the rescue suit. Either the suit cooler itself is just not powerful enough, because the void suit worked fine, or the internal cooling can't compensate for the increased temperature rate of increase.
The default power draw seems a too high for me, and the cooling system might not be strong enough.
