    2 cell Magicshine battery w/ Magicshine tail light?

    I dislike using the Y cable to connect my tail light to the same battery as my headlight. I was wondering if I could use the 2 cell battery (8.4v or 7.4v I'm not sure) to the tail light (3v) by itself and stash the battery under the seat?
    I know these batteries are all different because when I switched by Magicshine battery with an Amazon clone one night it just shut off within a half hour of using it.

    Yes, sure you can use 2-cell battery for your rear light. As for the run time - cheap unbranded copies are mostly junk nowadays, so I'd suggest buying genuine MagicShine one...

    Thanks, It's a loaner that was too cheap to pass up but you live and you learn. I'll get the 2 cell w/ charger for under the seat cause I hate all the wiring around my bike.

    After sitting for a while not being used, I brought my Amazon clone of a clone battery out of retirement. If you don't tape the connectors together tight the tiniest wiggle will shut the light off causing me to constantly press the button on again. They look exactly like the Magicshine connectors but aren't nearly as nice of a fit. I might use my Y connector to replace the inferior connectors.
