SpyderBatteries Black Widow 12S 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.
This 12S 4000mAh stick-pack is made from two of Spyder's 6S 4000mAh packs shrink wrapped together into one stiff brick. As is, the batteries are not wired together, but all you have to do is connect the two EC5 connectors to our Series EC5 Adapter to wire them in series and create a 12S pack. And for charging, simply remove the series adapter and charge them like you would any other 6S pack. It's as easy as that. Just like the 6S 4000s, these packs have a maximum discharge rate of 30C, while you can charge 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.
