    bluetooth BMS?

    Agniusm, I can confirm JBD-type boards do work for LiIon as well as for LiFe. Not only I am using two of them, one for 14s LiIon and the other with 17s LiFe. But when getting the 14s board by mistake I bought the LiFe version. It's only the default parameter values which are different: you just...

    bluetooth BMS?

    There is a post back in this very thread where schematics for every number of series connections are drawn (pictures too, if memory serves). Simple soldering job if you know what to connect and where to desolder. I did something similar to modify 16s in 17s. What is not that evident is that, if...

    CAv3 and legal gas: silly me!

    My bike uses since years a thumb throttle enabled through a 6-poles PAS. This was done via CAv3: pedaling is sensed but serves the only purpose to enable the throttle, thus keeping the bike legal (Europe): when pedaling stops the motor stops. Super-satisfied! Some time ago I updated the CAv3...

    bluetooth BMS?

    Same problem as serious_sam here: newest app version does not work on Android 9, older does. Is there an authoritative place to look at for app updates?

    bluetooth BMS?

    I am almost through this process, which I hoped would be smoother. After finding the right spots to desolder (informative pictures at p.37 of this thread), I had to (re)discover the fact that the new cells need recalibration, otherwise each cell is seen with a 25V voltage... This needs to be...

    bluetooth BMS?

    Yes, they do. Once you have a reliable source for good measurement, you can easily calibrate each cell (parallel string) individually via the PC software. AFAICT, this is not yet doable via the phone app.

    bluetooth BMS?

    Newsky256: yes, it's android app, link provided by eee perhaps one page back, it was a post on Dec 10

    bluetooth BMS?

    A little question for those using recent v.3.1.1013 of the xiaoxiang app. I find this new version very important, as it provides access to all the functions, including those which required the UART box (kinda impractical once the BMS is stashed away). But... I do not find anymore choice...

    source for 14s balance harness

    Hi folks, I'd appreciate a tip as to where to get a reasonably-priced 14s cable harness of decent quality for a smart JBD BMS: I am transforming one from 12s. I have ordered already from China but I'd like something that arrives here without too much of a wait. I am in Italy. Thanks for the...

    The Cycle Satiator, universal charger for the enthusiasts

    Reporting my success and full satisfaction story with the satiator. After 10+ years of cheap chargers (that never failed but were noisy, difficult to regulate, slow, plasticky, etc) I have now a couple weeks experience with the satiator. It's a different world. The thing is indeed expensive...

    bluetooth BMS?

    A quick update on my little problem above: solved super-easily by controlling everything through the new app version (3.1.1013), works like a charm and allows to modify all the parameters which were only accessible via the PC program before. Many thanks to eee291 for pointing me in the right...
  13. Q

    bluetooth BMS?

    I kinda remember it was possible via PC, but this requires to reopen the pack. Can you be so kind as to show me how it can be done via app? All I can find is an option to switch from one sensor to the other on the dashboard... Under "Params setting" my app shows nothing related to temperature...

    bluetooth BMS?

    I am about to connect everything after installing battery pack on the bike, cabling etc. When I fire up anc connect the xiaoxiang app, by tapping on the lock on the dashboard, I see it switch from the "Lock" red circle status, which I set time ago while working on the board, to another state...

    The Cycle Satiator, universal charger for the enthusiasts

    I am about to order a standard Cycle Satiator. Would some kind soul confirm to me that the programmer cable I already own for the Cycle Analyst is also good for the Satiator? Thanks in advance

    bluetooth BMS?

    Thanks, relieving news. It's quite difficult to understand from "documentation"... Cell count is OK, I was sleepy when ordering but not too drunk :-)

    bluetooth BMS?

    Hi there, I have ordered one such BMS from lithiumbatteriespcb.com, and it just showed up. In the meantime, I realized that I mistakenly (stupidly) ordered the LiFePo4 version instead of the LiIon version. While I wait for my cells to arrive, my question to you expert folks is: will I be able...

    opening a Bafang CST... and putting it back!

    Thank you fecther, this is a thoughtful suggestion, I will take it apart once more with your words in mind.

    opening a Bafang CST... and putting it back!

    Number of teeth is OK: I believe it's 42, anyway everything runs very smoothly once the motor is disassembled, or until the cap not not tightened. Opening it up again... it's obviously what I have to do, and I did it already. However, there is not much to misplace that I don't know what to...

    opening a Bafang CST... and putting it back!

    Hi there, I need help with a Bafang CST which I just opened to substitute the nylon gears. After opening, and learning that the motor was in perfect condition but for one split gear and another one with a damaged teeth, I ordered replacement gears, swapped them, mounted everything back, and...

    Charging 16s using 2x 8s chargers - what have I done wrong?

    I have in mind a similar approach for my 16s packs. Do you guys think that charging with 2 chargers fed by two distinct power supplies is safe?

    is A123 8s2p 4.6Ah enough for 500W bike?

    I'm throwing in my 2c of experience. I have a similar commute, short and steep, perhaps a bit longer than yours, and I am doing it happily since more than 2 years with A123 32113 cells (with threaded tabs). Nominal 4.4Ah, measured about 4.0Ah new, they were gray market at best. I am more than...

    Tesla Powerwall $350 / kwh Retail

    Hillhater: yes, I am positive of the 3kW max power limit. In detail: the limit is 3.0kW but the meter actually breaks at 3.3kW (10% tolerance); ii) there are grace periods, like 20% excess allowed for 1', the slightest excess of 0.x% will cut the power after 15'; iii) it is of course possible to...

    Tesla Powerwall $350 / kwh Retail

    Same here (Italy). AFAIK, the 7kWh model is meant to maximize the percentage of solar energy that you use locally, and to avoid putting most of it back to the grid. There are many financial models for solar panels at work, and I guess some are (and will be) such that self-consumption becomes...
