Not sure if anyone here will know the answer to this question. But I have an old chonry. It's the fold up shooting chory beta modem. Picture below. It uses 9v battery to power it. The battery runs out all the time and i always get the low battery warning. I'm tired of getting 9v battery for it since they cost like $8-9 for only 2 battery. I was thinking of cutting off the wire and attach an dean plug so I can use an lipo battery. The lipo battery will last way longer and I can always charge it. Then I won't have to buy those stupid 9v battery. But lipo comes in 2 cell (7.4v) and 3 cell (11.1v). The 2 cell is probably too low for it. The 3 cell when fully charge is about 12.6v. I am worried the 3 cell lipo will fried the chonry. So my question is, does anyone know if it's safe to use an 3 cell lipo battery for these type of chorny?
