Since batteries and the RMC have different cooldown durations, while in combat I'll use a weapons battery, then quickly open the inventory and swap in the RMC and then I only have to wait about 40 seconds instead of 2 minutes until I can boost power levels again. Then swap back to weapons battery after using the RMC.
I checked it a few days ago, and in addition to boosting power levels for a short time, it also removes any debuffs that you may have been hit with, so in that case, i think it works better than the ship batteries or the eps transfer ability.
1. You get the activation code from your box.
2. You log into your sto account on the website here. Not logging in to the game at all yet.
3. You go to support section of this site and click redeem key or better yet here is a direct link to it after you have logged into your account.
4. Once it is confirmed you then log into the game itself. Click on the c store icon on your minimap then under the legacy unlocks section you will find this op awesome device under all your toons.
The starship batteries skill at tier one allows you to spec the duration of it. It's cheap to spec at tier 1
0 points = it's standard 20 seconds
3 points = 25 seconds
6 points = 28 seconds (I chose this one)
9 points = 30 seconds
On a side note the enhanced plasma manifold which effects shields and aux power only operates the same way. The drawback to this device is it actually uses a console spot whereas the red matter capacitor goes in a device slot. I no longer purchase batteries anymore even with the 3 minute cooldown on this device.
