Default Battery hook up help

Hey guys,
I just got my Delta Ray today and the battery hook up looks to be just like the lipos I use in my off road trucks. I want to use the same charger that I use in my trucks, where I use a balancing board then connect the main red & black to a different harness. What is throwing me for a loop is the car charger that came with the plane only connects to the balancing lead. I need some advise on charging this battery. 2S, 7.4V, 1300 mAh.

Yup
Even my Cellpro Powerlab 8 chargers have the option of charging a battery ONLY through the balance cables. And, obviously the '8 chargers can also charge though both the balance and power connectors.

No problem here, just about any Lithium chemistry battery can be charged only through the balance cables with an appropriate charger. The restriction is the limited current value those balance wires can handle. That would be on the order of an ampere or two.

So, charging a 5000 Mah battery pack through the balance cable only could take four or five hours, again, due to the current limits of the balance wires.

So, if you've got an existing charger that can charge your 1300 Mah LiPo at about 1300 milliamperes (1.3 Amps) through the power and balance cables, just go for it.

is it a balancing charger? I it is, you can build/buy am adapter t use your balance board with, or buy a new balance board to match your new battery.

my larger has a bannana plug with a tamiya plug so I can alternate leads. you'll also want to match your esc to the battery.

slow stock prop reversal. it flies! easily! 543 watt dual motor bipe slow stick. push-me-pull-you. 242 watt 3 channel slow stick. 365 watt mini ultra stick. 415 watt mini contender. 810 watt ultra stick .25e. 220 watt alpha 450 sport (retired).

I think every plane that comes with a charger comes with cheap ones like that. Like Dennis said, it's a lipo, you can charge it like your car lipos.

Thanks guys. I changed the battery jack to a Traxxas jack. I charged the battery at 1.5A and it's ready to go. Hopefully today will be the maiden voyage.
