Thank you for contacting us. I am sorry for not getting back to you sooner. I am sure you have solved this already but I will try and provide some insight. Those links no longer work but from looking on the battery packs provided currently on their website it looks like they use a Deans Ultra Plug. Any of our hobby grade chargers other than our Hitec X4 Micro would work to charge this style of battery pack. If you still have any questions I would be happy to help. Or give us a call toll free at 888 654 4450.
