Okay, in the thread "Does anyone know how to make vehicles and robots for T20?" gentloser, I believe posted a design for a grav bike. I checked the design using the Vehicle Design Sequence and came up with a couple of questions.

On p. 236 of the THB in the text for Manned Control System the rule states that "If the operator is to ride on the outside of the vehicle, (e.g. on a motorcycle or grav bike) the control space size and cost is the same as for a remote-control system."

The first line for Remote-control systems states: "A vehicle that will be operated remotely requires only 10% of the chassis size and there is minimum size required."

How can the Remote-control systems require

**only**10% of chassis volume and have no minimum size rquirement?

My interpretation is that the 10% of chassis volume is the minimum size required for a remote-control system. I would like to suggest changing the sentence from:

"A vehicle that will be operated remotely requires only 10% of the chassis size and there is minimum size required."

to:

"A vehicle that will be operated remotely requires only 10% of the chassis size and is the minimum size required."

Next: How is battery cost and volume determined?

My interpretation of the rules are that 1 battery can store 1 EP that is discharged at a rate of 1 EP per hour. In the first text example a battery designed for to provide 1 EP every hour for 24 hours has a storage capacity of 24 EPs. If the battery is a TL 11 Modern battery cost is 24 x Cr0.30 = Cr7.2 and has a volume of 24 x0.04 vl = 0.96 vl.

In the grav bike example gentloser gives this information:

Battery - "I will fit a 5EP modern battery at a cost of 150cr and take up 0.2vl (you never know when you will want a few extra hours power)."

My understanding of the above is that gentloser selected a modern battery storing 5 EPs of power. Looking at the table on THB p. 241 1 EP x 5 x Cr0.30 = Cr1.5 and a volume of 5 x 0.04 vl = 0.2 vl. My cost is off by 150/1.5 = 100, while volume matches. If the cost is based on a 5 EP discharge rate every hour for 100 hours (5 x Cr0.30 x 100 = 1.5 x 100 = Cr150) then the volume would be 5 x 0.04 vl x 100 = 0.20 x 100 = 20 vl.

Could someone please clarify how Vehicle Batteries cost, volume, EP, and discharge rating actually work?

Very confused and in need of help.
