This product includes 2 LiPoly batteries for the Ergodox Wireless keyboard. Each battery is approximately 400mAh.
Due to shipping restrictions, international buyers cannot purchase extra batteries. For each keyboard PCB, international buyers may add one pair of batteries ($12). Buyers within the continental United States may purchase extra batteries.
In rare cases, we may be unable to ship LiPoly batteries to certain international destinations since shipping restrictions are subject to change. If such an issue arises, we will refund the cost of the battery and provide guidance for sourcing the battery through another channel.
