Just got a Team Orion 90C 5500mAh Saddle pack in the mail today. Instructions are limited. This is to be hooked up in series hey ? I've noticed a few photos of buggies with there wiring soldered directly from battery to esc, how do these guys charge. If I was to put pins on the wires already connected to the esc and wire it directly this would eliminate the Deans plug and balancing harness from being in the car when racing ! Then use the supplied harness to charge with deans plug and balancing harness. One of the precautions stated in the instructions is to remove the battery from the car when charging, Is this a good idea or not nessacery.
