Hi, I am looking to get a small electric park flier (like a slow stick -
6-8 cell, 400-1200mah ish batteries), and am wondering what to do about powering the battery charger. I could use my cars battery, but it is inconvenient, and it won't be around all the time. (I guess it wouldn't be safe to charge off the cigarette lighter, and put the charger and battery in the car unattended.)I could get a 12v power supply for my workbench, and charge at home. But around here, they are around $80-200 CAN. And then I couldn't take it to the field.
I could get a 12v battery to bring to the field - but I've heard that they give off a dangerous gas when charging them. And I was planning to charge indoors. One benefit is that I could charge off the battery while at home or at the field.
I don't know what to do. So, any suggestions? Is there a suitable type of battery that can safely be charged indoors? I may be using 6-8 amp hours of power out of it on a typical flying day. (How much power would be required for 2 hours at the field?)
Thanks, Colin
