is this 2S 4000mAh 35C battery selling for $12.85 any good?

Here is the link to the actual 2S 4000mAh 35C LiPo battery being sold on eBay: 35C 4000mAh 7.4V 2S Lipo Rechargeable Battery for RC Helicopter/Car/Truck/Boat | eBay


What type of balance connector does it have? There is a picture of the balance connector, but not mentioned in the description.


Will this battery be a good buy, or should I look somewhere else?

JST-XH balance conector (pretty standard), i've had a few BGY lipos in the past and they are awesome for the money.

Seems like a hell of a deal, the only thing I don't like is it's shipping from Hong Kong.

not sure how good it is as ive never heard of that brand but it does appear to have an align style balance tap, if you want a cheap decent lipo go to hobbypartz.com and look at their gen aces or sky lipo brands.

Continuous discharge rate: 35C
Burst rate : 40C
Seems kind of odd that the burst is only 5C higher than the continuous discharge, but I guess that's because its intended for aircraft.
Compared to a lot of other 35c 4000mah 2s batteries in a ground vehicle that requires high amps, I'd bet it would disappoint, but for the price and in a lower amp ride, it should be fine.

4000mah 35c is LOTS for a crawler and more then enough for a go fast, my hobbyparts gens ace 4000mah are 25c (and claim to have a 50c burst), never had an issue in any of my go fasts with them, (they now lug my e-maxx around with no issues)

4000mah 35c will support a 140amp draw

+1.

A 350mah @ 35C is a poor high power pack....but....it's a combination of "C" & mah that determines power draw. Thus, a 35C 4000mah pack has decent punch.
