Dejay Posted July 19, 2015 Report Share Posted July 19, 2015 The datasheet mentions such a board:http://www.evolvapor.com/DNA200/DNA%20200%20data%20sheet.pdfIf you are manufacturing a device that is designed to be used with three individual replaceable 18650 cells, an accessory board is available from Evolv to adapt from three individual cells to a pack and tap connector pinout, as well as provide cell-by-cell protection against incorrectly installed or reversed cells.

miskol Posted July 19, 2015 Author Report Share Posted July 19, 2015 Hi Dejay,noted with thanks, i'm aware of that but my question still stands... other than the fact that it is mentioned in the datasheet, has it actually been made available ? pics? more details?thanks.

Brandon Posted July 19, 2015 Report Share Posted July 19, 2015 Miskol, the board is not available yet. We hope to have it available soon. Link to comment Share on other sites More sharing options...
phoenikas Posted August 4, 2015 Report Share Posted August 4, 2015 Could you please let us know when can we expect the"accessory board" to be available for purchase ? Thanks Link to comment Share on other sites More sharing options...
blueridgedog Posted August 4, 2015 Report Share Posted August 4, 2015 I assume the triple 18650 mod that is on the market has a hand build balance connector that you should be able to work up yourself and use the on-chip connector. If you can solder the rest of the mod, make a triple sled and put the batteries in series, then you should be able to simply add a charge tap at each + and the - and be ready to go. Perhaps evolv can comment as to if this actually works. Link to comment Share on other sites More sharing options...
VapingBad Posted August 4, 2015 Report Share Posted August 4, 2015 It will work BRD, but the board Evolv plan has reverse battery protection. Link to comment Share on other sites More sharing options...

You could as a short term approach use diodes at each + tap. Link to comment Share on other sites More sharing options...

They also interfere with charging. You do need some fancy FET array for proper reverse battery protection. Link to comment Share on other sites More sharing options...
blueridgedog Posted August 4, 2015 Report Share Posted August 4, 2015 A single Mosfet on the negative...I guess we will have to wait as it would be so ugly as a homebrew. Personally I can't imagine wanting something other than a lipo though. Link to comment Share on other sites More sharing options...

Personally I can't imagine wanting something other than a lipo though.I was thinking a dual mosfet setup:#1 P channel w/ both the gate and the source is on the main (+)#2 N channel in the main(+) / gate#1 circuit with its gate (#2 ) wired to main (-) or last battery (-)In that case, any current coming from a wrong way (regardless of its voltage) trigger #2 closing #1 circuit where Vgate will be V source which is needed for complete shut down if I read it right.Pos: It is an always on thing w/o any consumption unless reverse polarity when it shutsCon: It doesn't necessarily save the batteries.In theory, it should (no closed circuit but the right one) but I have concerns.Any misbehaviour on the board side should do funny things. And I start to think, that some leakage current from the USB killed my fuse.P.S.:Thanks for the thread and thanks Brandon for the info.I was naiveAs it is stated available in the doc I opened a ticket asking for detailed info for design purpose (dimensions, datasheet, price etc.)That is what I got:HI GabeYou can find all DNA 200 info at http://www.evolvapor.com/dna200.phpThank You,SteveHope it doesn't mean that we are back to the good old days...

metroid Posted November 9, 2015 Report Share Posted November 9, 2015 I am really looking forward to this accessory board. Any news? I've been waiting for months Link to comment Share on other sites More sharing options...
