Hi John,
You don't have to replace your battery.? Just break open the battery case and replace the cells inside.? Some soldering required.? There are notes on this forum about how some people (including me) did it.? Plenty of opinions here about advantages and disadvantages of Li-ion vs. NiMH.? Either route will get you back on the air, reliably.? If you purchase a battery pack, measure its capacity while you still have the option to return it to the seller if the seller lied.
Cheers,
