In any event, I'm glad you posted this thread... gets me thinking about a DIY HID project. For anyone who has used the Trailtech HID, what did you use for a bar mount on your bike?
I looked at the battery you mentioned, but it wasn't exactly what I was looking for. It has the same Ah rating as the battery I bought, however it's 13.2v verses the 12v battery I bought. This means the light will be brighter, but the battery will run down faster due to higher current. Another reason was cost. Had I bought that battery, I would have had to spend another $35 on a smart charger. That battery comes with a dumb charger which means it will take much longer to charge and you run the risk of ruining the battery by overcharging (although given the slow charge rate this risk is low). For about the same price, I bought a battery that better suits my needs that comes with a smart charger. I have plenty of old water bottles I can use.
