Apologies for leaving out two references from my PDF on adding a LiPo to the DIY calculator (see 3 November post).

Here they are:
3. https://www.stcmicro.com/rjxz.html
4. https://www.amazon.co.uk/Emergencies-Por...BFDTQGIH4U
Similar versions on Ali Express for even sillier prices.

regards, Chris.
