Im thinking to use two batteries in my 80" edge with separate switches and all. How about the cross-sharge... is it an issue?? or should I use something to prevent it?? I have read from giantscalerc.com and heard that its not an issue

I now use dual batteries in all my planes over .40 size. The reading that Ive done says that cross charge etc would take days and is therefore not an issue. I plug them both in, turn one on, check the voltage, turn it off, turn number 2 on, check the voltage, and fly with confidence that batt. failure will not be the demise of my plane. When I discovered it to be the death of 2 planes, it seems like a no brainer to use dual batts., esp. with NiMH

Jep thats what Im been thinking too. I made an little test. I connect an almost empty nicd4.8/400mah and full nicd4.8/900mah into futaba 5ch receiver with voltmeter. I connected the full batt. into batterys place and the almost empty one into 5th.ch. waited about an 30 min and nothing happened, no cross-sharging etc.

Ps. I just made a test with those equipment, they will not get even close to my edge

Match your voltages. I have even used different capacities with out problems, although I do shy away from that. Have a great weekend

Henry,
since you have this all set up, why dont you check the current on the discharged battery and see whats going on there.

You will not have enough charge in a full pack to charge a discharged pack. Think of it as a battery with a little resistor in it. With this said, you need a higher voltage to charge the cells. Different capacities is OK but make sure that you are using the same voltage packs.
