Handle Bar Mount for NightPro HID or Halogen Bike lights

I purchased an "11.1V 4000mAh Li-Ion Battery Pack + Smart Charger for Portable DVD" to be used as a replacement battery for my bicycle HID light. The specs of the replacement battery are the same as those of the original except that it provided more mAH’s, but was priced at less than half that of a replacement from my light manufacturer.

I called customer service, and was sent the missing part in a couple of days. So, while I was not happy about the mess-up, BatterySpace corrected it with no problems. The only problem with the project is that the universal plugs did not include one that fit my light. This meant I had to make the decision to cut and attach a different connector. Not a hard task and a complaint that I really can't attribute to BatterySpace.

Some I found, but were available only as kits including charger etc. which I now have. I would like to be able to buy without charger for a reduced price. A really nice feature would be to be able to custom order a battery set given a set of specific
