Got an older dna250 board that refuses to skip the production charging test, and also refuses to pull more than .7a from the computer's USB port, so it never passes. Original programming date sept 2016, while my other 2017 boards skip the charging test fine.
Also as part of testing I put in SP9, which causes dna250s to bump to 1.100+v bandgap and fail production. Reverts to 1.02ish when i revert to SP5.
People should not be punishing companies for complying with the regulations. They are doing the right thing whether you think the FDA is doing the right thing or not. That said, in the aforementioned example $10 seems excessive to comply with the letter of the law.
You can meter the cells directly to check them, but it is true that the board will not read all cells properly without the B+ and B- connected. It will do exactly what you are seeing. The charge symbol comes on even in that condition.
Hi there, the preorder listing was for the time before they were allowed to be shipped by Evolv. Now that they can be shipped, the linked listing applies.
