The idea behind this suggestion is to make Heltec’s marketing efforts more efficient and easier for adoption by new members
You guys already have a tab called Accessories for each product that you manufacture and sell. So what is going to happen is that you could list these tested and works items under that tab.
Heltec needs to be very careful in what item you put under the Accessories tab. It appears you misunderstood the battery example I gave. This is what I meant: (ignore for now the issue about shipping restrictions on LiPo batteries), if you choose to list a resource Accessory, please make sure that you are listing the right resource.
Under CubeCell capsule, one of the the Accessories you listed is the 3.7v 1000mAH battery which could be an 802540 or 852540 battery. This battery is 25mm in width and 40mm in length! 8.5mm or 8.0mm thickness is practically the same and acceptable!
3.7v 1000mAH LiPo -could work with the CubeCell board and not the CubeCell capsule
For an 802540 battery, please note in battery specifications this means thickness 8.0mm (in x.x format), width 25mm ( in xx format) and length 40mm (in xx format)
An 802540 battery cannot fit into the capsule. Instead the say 701418 roughly fits
One of the batteries which meets the specifications that fits in the capsule is this
LiPo that works correctly with the CubeCell capsule
Heltec needs mention the right resource and add the correct comments as you have done.
BTW the capsule battery is originally designed for RC model airplanes. There is a trick for shipping these types of items
For forum members please feel free to continue sending in proven components (hardware and software) I will continue to volunteer to track those and make things easier for later adoptees of the CubeCell platform. My inspiration is from @rsmedia
