I just realized that I could have bought the cheaper unprotected batteries as the Vamo V3 has a protection circuit built in. I've read the protected ones are also a bit longer. Will the protected ones still work in Vamo V3 but is overkill or will they not work at all. Panasonic CGR18650CG 18650 2200mAh Protected Rechargeable Lithium Batteries (2-Pack) That's what I purchased. I've only used the batteries that came with vamo v3 so far...I hope those ones I linked will still work.
