Replacment 24V Lithium LiFePo4 Battery for the X-Treme™ XB-310Li Mountain Electric Bicycle.
If you bicycle was manufactured in 2011 and later this is the battery you will need. It is higher quality and able to substain climate changes far better than the LiMn battery packs used in 2010 and earlier. We no longer offer the LiMn pack, but this advanced LiFePo4 is offered at the same price. You can upgrade your battery easily, however, you must also purchase the compatible charger. Search our site for part #XB310-250-2 and add to your cart also if your bike did not come with the LiFePo4 system.
