Phone Guy Posted October 1, 2022 Report Share Posted October 1, 2022 I'm retrofitting a DNA 250c board into a 2 cell enclosure. Will a 250c charge the 2 18650 batteries without the jst connected? (The jst that connects to the individual cells) If the jst is needed, I'm not sure how to wire them correctly? This mod (dovpo Riva something) has the bottom flap shorting the 2 cells to complete the circuit. So the + and - are connected on that flap.

Wayneo Posted October 1, 2022 Report Share Posted October 1, 2022 YES! You need either the JST or individual wires connected to the board. There's a 2S diagram in the datasheet. https://downloads.evolvapor.com/dna250color.pdf 2 Link to comment Share on other sites More sharing options...
awsum140a Posted October 1, 2022 Report Share Posted October 1, 2022 You also need to set the number of cells, using eScribe, in the configuration for the mod and save that to the mod. 2 Link to comment Share on other sites More sharing options...
dwcraig1 Posted October 1, 2022 Report Share Posted October 1, 2022 I did my 250C 2 cell like this. I solder bridged to the batt + and batt -. Could use small wire I suppose. 2 Link to comment Share on other sites More sharing options...
