    Splitting up a 14s pack to balance

    Been out riding and enjoying the bike so not been posting. Turns out my other charger the 52v 2a one outputs exactly 57.4v which perfectly takes me up to 4.1 per cell with zero messing about. The cells are Samsung pink 35e all brand new from nkon in the Netherlands. I bought 70. I used 56...

    Splitting up a 14s pack to balance

    Got all my charge leads soldiered on today. Im going to use an old 48v 2 amp charger to get the pack most of the way to 4.1 and then use balance charger to top off.

    Splitting up a 14s pack to balance

    My amp discharge rate is set at 10 i may up that to 11. My pack is only 4p so 4 amp charging is as high as id ever want to go. Id rather have a slower charge and longer pack cycle life.

    Splitting up a 14s pack to balance

    Ok cheers. I would probably have tried if you hadn't had said :shock: as stated above once the pack is balanced it shouldnt need to much keeping on top of with the cells being new. Err. Not sure why i mentioned no bms. I didnt think it was that obvious. I was going to use a bluetooth bms so...

    Splitting up a 14s pack to balance

    That option has gone as the pack is built. Plus my charger is dual 6s. My bulk 52v charger is ok i guess. But i wont be using a bms. The cells are brand new Samsung 35E's Im only charging up to 4.1 and discharging down to 2.8 for cell life extension

    Splitting up a 14s pack to balance

    Cheers for the prompt reply. Would charging the two 5 packs at each end together be ok leaving the 4s in the middle to charge on its own after? My charger is the ..HTRC C240 rc charger LiPo DUO AC/150W DC/240W Dual Channel 10A Balance Discharger. Not had it long but it does seem that the 2...

    Splitting up a 14s pack to balance

    Hi. Just got my first ever battery welded together. Went very easy with my diy car battery welder. Ive added 3 balance leads 5s 4s and 5s to make the 14s. Is there any technical reason why i cant and 4 charge leads at cell 1 negative, the join between 5 and 6, the join between 9 and 10 and...

    New "TSDZ2 Torque Sensor Central Motor"

    I have the narrow wide because i do a lot of off road rough stuff. And the 36 because its very hilly where i am. If you dont do to much rough stuff or you have a clutch rear mech you will be fine with a standard pattern chain ring, you could also try one of those plastic chain devices that screw...

    New "TSDZ2 Torque Sensor Central Motor"

    yes it will fit i swapped mine out for a 36 chain ring as well, on 26 inch wheels and a fairly standard mountain bike casset i find the gearing to be perfect with the assist. i would try to find a narrow wide style chain ring though, i splashed out on a hope one but raceface and others make...

    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    If you go here https://www.eco-ebike.com/blogs/eco-cycles-instructionals/tsdz2programmingfromscratch You can re configure your motor controler fimware to change the battery voltage and max amps. Its very simple to do. I used this method to use a 48v battery on a 36v motor. Then i moved on...

    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    ive been wondering about this for a while now and still no closer to finding the answer. given that i can select watts and amps limit in the settings and i know my battery voltage lets say its a freshly charged 48v battery putting out around 52v if i set the watts limit to 600 and the amps...

    building my first battery

    Hi 999zip999 Yes ive been looking into how im going to charge this and charge all the cells before the build. I was recommended a power supply type charger, but ive gone for an rc charger. An htrc c240 duo. On the back of that if reworked my pack design from a 5p14s to a 6p12s my motor is...

    building my first battery

    When it comes to the actual matching up of the 5p packs. Ive been dreading having to fully charge all 70 cells 2 at a time on my nightcore 18650 charger. Just a thought i had this morning. Ill already have a 14s bms, can i make a 14 cell battery holder and create a temporary 1p14s pack to...

    building my first battery

    Fechter I love the simplicity of your build p+s out of single nickle sheet. Would the fiberglass tape not stop my pack from fitting together neatly given that its not going to be in straight lines as yours is but rather the hexagonal pattern? Point taken about the paper positive end insulator...

    New batt for TSDZ2 /cold climate/BMS compatibility questions

    Hi Cant coment on the other batteries but im looking at building a pack from Samsung 35e cells. They do look good. Another member on here told me that unless you charge them at 1amp your recharging cycles will take a big hit. Can charge at 2 amps but very bad for the life of the cells. Hope...

    building my first battery

    About the HLG The thing i found was a power source for led lighting fixed at 5.something amps and said nothing about possible adjustments. I did see the luna charger and a post somewhere from a guy complaining they were hard to get hold of. The reply was to use a 60v 5amp lab power supply...

    building my first battery

    :thumb: Ok cheers for that flippy. Looking at the data sheet it seems to agree with what you are saying. The bike is purley a leisure bike, no big daily commutes so i could probably live with a poor duty life but i would need a charger that i have more control over. Given my needs could you...
