I want to replace the baby mojos next year with teal decoys. I don’t want to mess with 4 aa battery packs however. To my knowledge, this is the only way they come. Is there enough room in the body of the teals to fit a rechargeable 6 volt battery, like the ones in the lucky ducks or baby mojos have? Lithium rechargeables would be another better power source altogether, I don’t know which one to order that would fit. The wire splicing in the conversion is easy, the challenge is finding the battery size small enough.
