We are moving component from a (RIP) trainer to another plane and considering upgrading the battery pack for more flights in a day without recharging. The current battery pack is 4 NiCad’s and I’m considering 8 NiMH (4x2) in parallel, so we have the same voltage, but more current. NiMH are lighter for the same current, but we will have 8 instead of 4. The new plane is lighter, so we are offsetting some of the weight gain. I'm just about ready to balance the plane, so I need to select and buy the battery pack, so it can be located correctly.

Any concerns, issues? What should I be looking for or be aware of?

Thanks in advance,

Jack
