    Building a 2S battery for helmet mount?

    Looking for some information on building a 2 cell (2S) battery to mount to my helmet so im not carrying around a 2nd 4S pack in my backpack to run the helmet light.

    Anyone have any good info/DIY instructions to help a guy out?

    Using Ituo WIZ XP3 lights on both bars and helmet.

    Thanks!

    Easier to just buy this...

    http://kaidomain.com/bike-lights-and...ith-10cm-Cable

    Been reviewed here and pretty favorably...

    There is also a version with a longer cable if the 10cm is too short for your setup.....

    I use the linked battery. Works well enough. Just be prepared for slow shipment from Kaidomain. It may be better these days, but in the past, I've forgotten all about a KD order after a month or so, then had a nice surprise when it finally showed up.

    I placed an order for a few things from KD 4 days ago. We'll see how long it takes...

    I ordered a KD-2 light back in Oct 2018 and it was only $15.88 with free shipping. Maybe they need a particular shipping method for lithium batteries?

    However, I go to checkout and there is still a free shipping option when purchasing the 2-cell 18650 pack.

    Weird. I ordered 2 lights, 1 battery, and a couple small things totaling about $83. They sent an email stating they had to ship via DHL due to the battery, and they asked if that was ok. I said sure, no problem. Everything arrived fine via DHL. I checked and there was no additional charge...

    I prefer lipo batteries because they are lighter and have a higher capacity
