The Venom Battery packs for the Xbox 360 controllers are the best I've seen on the market, especially for this price. After bitter disappointment with other BP - for example, of the brand Mad Catz, which were not tailored to the MS Xbox 360 Controller or did not fit properly let alone working properly - I was skeptical of this unknown British manufacturer. But the Venom packs perfectly in the Orig. Controller, they can be charged cable to the Xbox 360, both with a single (USB) and therefore offer very good gameplay. A star deduction there was because a load (several hours. Overnight) holds mostly for 3 days (with daily games of 3+ hours). However, the charge status can be checked at any time via the Xbox Guide button. The manufacturer recommends that the battery pack before recharging completely "empty play", so I recommend it to you as well. Therefore, empty games is the BPs as long to use the controller to shut down this by itself and the message "Please reconnect controller" appears on the screen.
Another tip: After playing take the Battery pack from the controller and set it aside, thus they are discharged less quickly. In order not to interfere with the reception, should no metallic Gegenst. (Eg game packages) are in the immediate reception area of the Xbox 360, they could interfere with the transmission of console controllers. I do not advise to connect the BPs via USB cable and play with "wired" Joypad, this can damage the BP quickly. Lieber (wireless) empty play and recharge overnight.
