"Some have mentioned installing an XT-60 connector & balance connector and charging with a typical LiPo HV charger. The problem with this is that the BMS doesn't know the battery is fully charged. What happens is you can't take off because the Anafi, FF6 & the BMS all see zero, (0) percent. How do I know, been there done that! "
So how is it possible to charge with that 3-socket charger?
In the picture, you are also charging with an external charger via the drone connector.
If I think correctly, do you think that bypassing the BMS, the cells cannot be filled directly because then it will not take off due to 0%?
But it makes sense for someone to install a balance connector on the original battery, but the charging current has to go through the BMS.
You haven’t tested that if you plug it into an external charger after a normal USB charge, what does it show and compare that to when you charge with an external charger?
