I am not familiar with the k350 battery set up, but are there two<br clear="none">
battery pods with 3 x 12V batteries in each pod?<br clear="none">
What are the other k350 owners doing? Do they run the 3 thrusters<br clear="none">
off the 2 battery pods similtaneously i.e. connect both pods in parallel.<br clear="none">
If you did this then you would only be drawing half the amps off each<br clear="none">
battery pod, than you would be if you were using one.<br clear="none">
I wonder what traction batteries mobility scooters use?<br clear="none">

Now most of the time I will be using the thrusters at minimal draw and not all 3 at the same time and the 6 lights will probably never all be on at the same time.<br clear="none">
> If everything was wide open, I would be pulling about 155 amps from a bank that has a reserve capacity of 125 so it would deplete the bank rather fast and may even damage the batteries due to a quick drain? So,,, first question...would 2 OTT wire be sufficient from battery source to bus bar as long as I am not running full tilt on everythig and second... since I have to stick with a lead acid system due to design, can I get a group 27 battery that can deliver much more than the 125 amps I have on my boat?<br clear="none">
