    Mod the baterry pack of ks-14b

    Hi @Snoopy63 I have the battery and all the tool to do it, but I have not done it yet. I am sure will fit, the reasons I have not done yet are lack of time, and that some people on the Russian forum have told me that I need to connect the gates of the mofest (transistor) of both batteries, so that if one battery is in overcharge both can shutdown at the same time.

    KS16S Serial Number Issue

    You can find it here: http://t.me/kingsong14m I have not tried, and don't know it works or not. If it is for the ks-14M make sure that you really need to change the serial number first. There is alot of info on the Russian forum. I am not responsible for any demage to your wheel or anything else cause by this change.

    I have done already on mine. But I have the first version of Ks-14M. I just did it because I intent to add a second batery. I bought one 1 month ago but still havent had any time to install it. On my, I limit the top speed to 25km/h a é rarely go above 20km/h

    I can not understand what you mean. What wheel do you have, and what happen?

    You need to flash the firmware of 14D on ks14m. With just one battery and the 14D firmware I can barely get 25km/h. You need to use 14Dv1.07 or before, on v1.08 and later kingsong start to check for the serial number on the wheel. There is a tool to change the serial number, but if you change the serial number I believe the wheel gets recognise has ks14D by the app, and I am not sure if you need or not to change the firmware manually. Note, that there are 2 version of the KS-14M wheel, and the way to update are different. I was able to get a cheap battery for my KS, just need to solder the right connector to it. I am just giving some information that I found on the internet, I am not the creator neither responsibility for nothing that happens to you. Instructions at: https://electrotransport.ru/ussr/index.php?topic=51391.180#topmsg you can use the translator for that Check first if you have the KS-14M or KS-14SMD. The instruction are for the first one, if you have the second version it will (may) brick the wheel.

    Mod the baterry pack of ks-14b

    This is not considered chassis wiring as it is not on free air, but I understand your point. I don't know how much is the power drain from the motor, I am considering that can be 20A for a very few seconds, and 5A for normal load. Maybe I am going overboard with the thicknesses of the cables, but I don't like to mess with li-on batteries. As the battery as been sitting in a shelf for 2years and half, I would like to do a complete charge and discharge to measure the capacity of the battery, but I don't have a load capable of 100W, just 5W ?

    Mod the baterry pack of ks-14b

    Today I have open the batery pack and one of my assumptions was right, although never used it is a old pack from December of 2015. I like the fact that there is a fuse on the positive discharge cable but I will probably remove when I transfer the pack to my wheel. The cables used are only 16AWG, I was expecting something more like 12AWG, I don't know if I should change but I would prefer to not remove the heat shrink of the battery pack

    Mod the baterry pack of ks-14b

    It is the same model as KS-14D, but with just one battery pack and without the led and speakers. I am following the site ecodrift.ru for some information but I doubt they will help, I will try anyway

    Mod the baterry pack of ks-14b

    Three cables connect to the battery. See on my second post. Once I open the wheel I will be sure, but looks like most times the BMS are common positive , something like the image attached. So in the battery pack of KS-14b has the charge leads (C+ and C-) and the discharge leads(L+ and L-). IF my KS-14M in its first battery uses a bms with common positive, and the pack I am trying to mod is also common positive, I can: join together C+ and L+, this will be the red cable; and L- will be the discharge cable that connect to the board, black cable; and C- the charge negative that goes to the negative of the charger, purple colour. (the colours can be seen on the second picture) So I agree with you, if the configuration on the wheel is common positive. Probably to discovery if this is the current configuration I will use a multimeter for it, disconnecting the first battery and see if the red cable that goes to the battery is directly connected to the positive of the charger. On the wheel I don't have any marks of what colour means. Thanks, I was just brainstorming and is always good to talk about it with some one
