SpyderBatteries Black Widow 4S 4000mAh 30C LiPo
SpyderBatteries provide an unbeatable combination of price and performance; their low internal resistance and high cycle life ensure that you are getting maximum value from your battery.
While their C ratings may be 30-100% lower than other brands, you'll find that Spyder packs will regularly outperform their competitors' higher rated batteries. SpyderBatteries products are always advertised with their actual C ratings - compare their internal resistance values with other brands and you'll see the difference.
The 4S 4000mAh pack has a maximum discharge rate of 30C, while you can charge it at up to 5C to get back to action as fast as possible.
Note: Due to recent postal regulations, we are no longer able to ship lithium batteries internationally via USPS. For international orders containing batteries, please select UPS, FedEx or DHL as your shipping option.
