Babaji_on_wheels Posted October 7, 2019 Share Posted October 7, 2019 Hello All , I am from India and have recently purchased a King Song 14D . After riding for 4-5 Days I have become real addicted to it . Only drawback is the wheels doesn't acclerate fully after battery drops down to less than 50 % . I am now willing to upgrade my Battery or make a new one myself . I want to know if the KS14D battery have a built in BMS controller . Has anyone tried to Teardown a King Song Battery? Please share your reviews on it . Thankyou 1 Quote Link to comment Share on other sites More sharing options...
The Fat Unicyclist Posted October 7, 2019 Share Posted October 7, 2019 Hi @Babaji_on_wheels - Welcome to our forum. Yes, there is BMS wrapped up inside the King Song batteries. The 14D does have different battery size options though. What Wh do you have? Quote Link to comment Share on other sites More sharing options...
Babaji_on_wheels Posted October 8, 2019 Author Share Posted October 8, 2019 Hi , I have 340 Whr Battery . Seems to get over very soon after a few min of 25 + kmph runs . I was thinking maybe I can make a custom Pack with Sanyo 3500 , 18650 . 1 Quote Link to comment Share on other sites More sharing options...
The Fat Unicyclist Posted October 9, 2019 Share Posted October 9, 2019 There is a 420Wh option available for the 14D... It should give you a bit more performance (and would be easier than building your own pack. Quote Link to comment Share on other sites More sharing options...
FlyboyEUC Posted October 9, 2019 Share Posted October 9, 2019 If budget is not an option, get the 14S. Thats what I did and I love it! I had the 14D for about 4 months before I upgraded to the 14S. I still ride it to this day amidst my 18XL and MSX 2 Quote Link to comment Share on other sites More sharing options...

I still ride it to this day amidst my 18XL and MSX @Flyboy10 makes a really good point... the inner working of the 14D and 14S are the same... By swapping just the batteries, outer shells (and pads on them) you could transform your 340Wh KS-14D into an 840Wh KS-14S. Which would give you so much more range before any speed throttling! 1 Quote Link to comment Share on other sites More sharing options...

If you like to work with your hands and want to save a couple hundred bucks then you can do that. Or you can sell your wheel and buy a new or used 14S. 1 Quote Link to comment Share on other sites More sharing options...
Babaji_on_wheels Posted October 10, 2019 Author Share Posted October 10, 2019 Thankyou @Flyboy10 and @The Fat Unicyclist for helping me out here . I will save up some money and get the Batteries of 14S . Regarding the outer shell , I will make a Resin Infused one with Composites , as I have access to Carbon Fibre . I hope King Song doesn't feel bad about me modifying the wheel !! 1 Quote Link to comment Share on other sites More sharing options...

The creativity there is simply amazing. Quote Link to comment Share on other sites More sharing options...
