Btw. it works great with this NI
1.6v rechargable batteries
I'f your LiPo charger can do storage charge, just load 2 in series (3.8v) and you don't need a special charger for them.
i bought four of these batteries along with this battery holder: https://hobbyking.com/en_us/4-x-aa-battery-holder-rx-pack.html
but how to hook up two of them in series to the charger in order to charge them (with your method of using the LiPo storage function). i could place two of them in the battery holder and short the two free slots of the holder in order to get the series connection. but connecting the servo plug of the battery holder to the balance connector of the charger won't work. do i need to make an adapter from the servo connector of the battery holder to the charger connector (in my case XT60), in order to charge the two batteries? (but in this case, what has to be connected on the balance connector?)
my charger is a Turnigy Accucel (https://hobbyking.com/en_us/4-x-aa-battery-holder-rx-pack.html)
EDIT: dummy me was writing ESC all the time, instead of charger.
