With this style battery holder,

If I attach a charger to it, can I charge the batteries while in the holder. I ask as I would like to keep the batteries inside the D5 Bruder conversion, rather then have to remove them to charge them. OR, if you guys have a better suggestion, I'm all ears. I already know I'll be placing a charge port on this thing. It's easier to open than stock, but will still be a PITA to open JUST to change/charge batteries.
