Hi all,
There are tons of multi-chargers available for P3's and P4's, but I haven't found anything decent for P2's. So I'm wondering if any of the enterprising souls here have made a home-made, custom-built charger to charge multiple OEM DJI batteries simultaneously.
(I am a Part 107 pilot and I go through a lot of battery power when I fly for work, and in order to avoid downtime I'm constantly charging 4-5 batteries simultaneously. Currently, using 4-5 separate DJI chargers, there are wires running everywhere and it's a mess.)
As far as I know, it should be very feasible to do such a thing:
I understand that the DJI batteries themselves include the necessary low- and high-voltage shutoff and charge-controlling circuitry, so the charger itself is no more than a simple 12V power supply (more like 13V in reality). If that's the case, electrically speaking all that's required is a 12V (13V in reality) power supply of sufficient capacity to be able to handle the current drawn by multiple batteries as they charge.
Then it's a simple matter of fabricating an enclosure of some sort and wiring the terminals.
(I'm envisioning a plywood box with slide-in slots for six batteries that can either by plugged into a 120VAC wall outlet or, as is more often the case for me, connected to my vehicle's 12V electrical system.)
Any thoughts?
