  • I'm planning to use this LiPo cell with a Solar Buddy board for charging. I'm trying to find out whether there is an NTC thermistor installed or not, the data sheet for the protection circuit i quite hard to read and only states XXX on the NTC spec. My application will be outdoors all year, i.e. the temperature will be well below freezing during winter and if I understood it correctly you really should avoid charging at subzero temperatures.

  • +1. I would also like to see the NTC pin connected to a header.

No public wish lists :(
