wehey Posted September 12 Share Posted September 12 Hiya all. I am thinking about using my KS16X battery for another application. Whats the maximum output that these batteries are capable of? Thanks Quote Link to comment Share on other sites More sharing options...
mmk Posted September 12 Share Posted September 12 Max output could be quite extreme, depending on how flammable the surroundings are... sorry, hard to resist. Quote Link to comment Share on other sites More sharing options...
alcatraz Posted September 13 Share Posted September 13 These high capacity ~1600Wh 21700 packs use 10A cells in a 20S4P configuration. 84v full charge voltage and 40A continuous power draw. It can do more than 40A if it's a short time, up to whatever fuse is on the bms. There are two. Assuming that you intend to use the packs in room temperature. If you go into freezing or hot ambient, your max current draw diminishes. As for charging the packs off the wheel, that could require some thought as charging is sometimes controlled by the control board (absent). On gotway/begode wheels the charging is independent of the control board. 1 Quote Link to comment Share on other sites More sharing options...

There are two 777 Wh modules using 18650 cells (AFAIK initially LG MJ1 were used, later changed to Samsung 35E) configured as 20S3P each, which gives 1554 Wh 20S6P for entire battery. There's a 30A fuse in each module and it's best to not exceed 24 A cont discharge current per module. 1 Quote Link to comment Share on other sites More sharing options...

(Both 35E and MJ1 are 10A cells.) Quote Link to comment Share on other sites More sharing options...
