Slower speed with low battery?

[leovampire]

Lust like a wind up toy as the spring unwind's the toy slow's down true to life and game effect you are experiencing.

The electirc engine's require a certain amount of base AMP's available to produce output. As the AMP's lower down so does speed. Voltage always remains constant it is the AMP's that produce power.

There are lead plate's inside of the plastic case of the battery with electro light acid inside of the battery. As the lead plate's start to sulfate due to lack of charge the AMP output of the battery start's to drop.

It was because of this sulfation that happens in the batteries that you ended up with a build up on the contact's and also fume's in the sub that could be ignited with a spark if you do not vent often enough on the surface. Also water had to be added when batteries are charging due to the acid being turned to gas so it would disapate.

Also batteries where usualy changed when you return to base seeing the lead plate's slowly degrade with them being drained down so far in charge and then recharged so much.
