    BMS Hook up for 14s 2P lipo - without smoke and fire!

    Cool - so seem that you can parallel the main leads and parallel the balance lead. Will do it outside just in case.Yes made the mistake of jointing two pack before in parallel with 20% voltage differences..i did not have a BMS in the lower one so it ran away....... See video of local fire...

    Bms to be replaces

    I have had success hooking up smart BMS's that you can connect to via bluetooth or a PC They cost little more but as you van see the voltage of each cell then you know if it is working or not or balancing or not Just get the right amp rating and cell series plus chemistry for your application...

    BMS Hook up for 14s 2P lipo - without smoke and fire!

    Looking to hook up a BMS to a 14s 2P pack. I am fine with the BMS side as I have done this before...on a 13s pack. The question someone might be able to help we with is around if it OK to hook up 2 X 14S Lipo pack in parallel and then hook up to a BMS. The 14s packs are multistars that are...

    Stealth FUTR owners builds and pics

    +1 to see a strengthened Beta swingarm with 150 drop outs. Surely this could just be an option once the guys get a chance to design and build it. At Shanghai airport right now coming home from the Shanghai bike/ebike show with a Mxus v3 - tempted to open the box to see axle width.Reading up...

    Strange Behaviours - could be hall sensors but ....

    thanks - yes that is what i was suspecting that the weight allow for this. Interestingly when the issue first arose, my wife could get the bike going with her weight and then turn the throttle gently and off see would go....then about 250km later this was no longer possible..i wonder if a...

    Adaptto Mini-E/Max-E Owner's Thread

    Just wondering if any Adaptto owners have had experience charging at around the 12V mark. I am looking to set up a solar charing system with some old but usable Headway batteries.I am looking to configure into 4s to suit my solar system giving a fully charged voltage of around 14.4V. I have...

    Electric Hang Glider

    Hey great videos and information - thanks for sharing Are they lipo batteries that are strapped to your back ? as a hang glider pilot this is the bit that would freak me out Yes unlikely- but a battery fire on climb out under load could never be fun ! Thought? Would be good to a system you...

    Charging via a parallel connection - not working anymore !

    The picture does not show it too well however it very much appears this was a shunt and looks broken. If I look at board there are other part of the board that are labelled KXXX and there are just stunts. (Solder wires bridging to areas) I am assuming areas labelled K on the board are...

    Charging via a parallel connection - not working anymore !

    So I have opened the damn thing (the emc1000 charger) and to my surprise and delight I may have located the source of the issue.....looks repairable. On the PCB there appears to be a component missing (blown up), or it may be a broken shunt.(not sure) Where do I find out what I need to repair...

    Charging via a parallel connection - not working anymore !

    too answer previous posts, charger has been working fine when connecting directly to the battery I worked a bit more on this and it appeared the issue why there was no response out of the charger was a bad connection between the special lead I made up to connect the charger to the parallel...

    Charging via a parallel connection - not working anymore !

    Hello hello. I thought I would throw this one out to the friendly Endless-sphere community...to help get some sanity around this ! :P I have a 20s lipo ebike that I am looking to set up so I can bulk charge in parallel. What I mean be that is to have a parallel connector running off the...

    Where to source a 72v lipo bulk charger ?

    Thanks all for the replies....my charger turned up in the post and is working fine....would have good if BMSBATTERY could answer basic emails. I have also looked at the GREENWELL chargers from this site... http://www.aliexpress.com/store/313864 They appear to have much cheaper shipping charges...

    Where to source a 72v lipo bulk charger ?

    Hi Guys, I am looking to source a bulk charger for my 20s lipo set up for my ebike. I have used BMSBATTERY.com before with success some years ago.( 2 batteries delivered) This time I have ordered and paid for a 72v charger and a few other bits with no response in over 3 weeks.(4 emails sent)...

    EMC-2000 charger from ecity (1500 to 2000W)

    Thanks Doctorbass and dnmun for your replies.... Well I opted for the option to short the relay to see if I could get the charger working this way, Took the board out and before I got there, i switched it on and puff....took out my house circuit..the board is shorted an we could not find out...

    EMC-2000 charger from ecity (1500 to 2000W)

    Managed to get the display changing when I adjusted the pots...but if the display pot can change the display to read what ever you want...what is the true voltage set too so how do you know what voltage the charger will output.....sticking a volt meter on the end of the output is only giving...

    EMC-2000 charger from ecity (1500 to 2000W)

    I am having a bit of a bad run at the moment with my electronics. I must be defying a few unwritten laws I have no idea about because in the last few days ..I may have blown up a controller (should have seen the spark and finger burns) , definitely caused my Cycle Analyst screen to stop...

    Jamming those lipos in !! advice needed

    Good Point - on the cannot get them out scenario. That could have been funny - In my case they would be stuck in the frame. DOl ! :oops: Having said that I guess the Lipo will only puff, or expand in one direction. I may be able to stack them to there is more room to expand in width and less...

    Jamming those lipos in !! advice needed

    Hi all, I am doing a new 5000w ebike build and sorting out my battery solution. I have purchase some discounted A spec 4Ah 10s lipo batteries to go inside my bike frame. :lol: I can pack them in a block of four with the top section of the frame with a further 2 lipo sticks down the bottom...

    BMS assumptions - have I got this right ?

    Really interesting reading. Some of my post outlined I am heading toward LIPO battery pack. Certainly the use ofmy BMS on a LIPO pack would not make sense. I think the point was it would be Ok in terms of Max cut off voltage (3.9v)however the cutover voltage on the discharge would be too low...
