My watter bottle battery life is not what it used to be. So I'd like to replace it. The one from Jet Lights seems to be out of stock:
13v 3800mah NiMH Battery - JET Lites
Would it be possible to get another similar 13.2V battery like this one:
Water Bottle Nimh Battery: 13.2 V 5Ah (66 Wh) with Trail-Tech Female plug for HID / Halogen Bikelight
and modify the connector worse case? Would probably take the entire wire from the existing battery and solder and wrap the wires to the new one. Has anyone done this?
