The plastic battery holder clip is very rigid, making it difficult to change batteries without the clip draging hard against the battery as it is remove or inserted, potentially damaging the battery. I ended up removing the original battery clip and reassembling with color coded plastic "washers" made from large zip ties. Just drill holes the correct distance apart in the zip ties and cut to desired length. Note that the front and back holes are not the same spacing. Then use the more traditional rubber bands and/or Velcro to hold the battery in place. I put a small piece of Velcro under the battery to prevent it from sliding while the rubber bands hold it firmly in place. This approach is lighter by a couple of grams and allows easier battery exchange and easy experimenting with alternate 1S batteries.
