Hi All-
I've searched the previous posts for this and can't seem to find any information on building a true parallel battery charging rig. Does anyone know what kind of connector DJI uses for their batteries? It doesn't look like any other I've seen used in RC. My intent is to solder up some adapters to connect the batteries to a parallel charging board like this one http://www.hobbyking.com/hobbyking/...ging_Board_for_6_packs_2_6S_T_Connector_.html and apply 17v DC with the amperage appropriate for however many batteries I'll be charging at once. That should get me multiple batteries charged during the same time it takes to do one.
It seems pretty clear that the DJI batteries themselves have the balancer and LiPO charging logic built in them instead of in the charger itself. The label describes it as an AC power adapter and nothing else.
If there are no pre-made connector form factors, I can just build some but it would be ideal if some existed that were polarity protected due to their shape.
Thanks!
P.S. Not doing anything crazy here. I've flown collective pitch RC helicopters for years and am very familiar with doing this for other LiPO batteries. Totally get the precautions and necessary steps to be safe doing this. Those parallel boards all over eBay are kind of pointless since you have to split up the current across all the batteries you are charging so it just takes longer. And I'm not interested in dropping the $500 on the pre-built charger that one company has. This is completely doable with gear I already have except the connectors.
