hi, I gather I can use the 980HZ original OSMO batteries in my OSMO+, but this comes with a higher capacity 1225hz battery which uses its own charger ... but can also be charged on the original battery charger ... but the original 980hz batteries cant be charged on the one that charges the 1225 battery.  I THINK this, can anyone confirm?

I also can't find a part number for the 1225hz battery.... and there are also some batteries for sale that offer 1120hz (not on DJI website though so don't know if they are 'genuine')

u can charger both high n low capacity batteries on the new battery charger...but if u charge ur high capacity battery on the original battery charger it wont charge full...i dont think u shld use non dji battery on dji product thou...since dji product is sooo 'sensitive' lol...
