Re: bluetooth BMS?

As you didn't include a circuit diagram on how you wired everything it's hard to make assumptions. For rhe wireing its just wired like two separate batts. The only connection between the batts is the main output plus and minus. The reason i have it liue this is that sometimes i use the batts at 36v...

Re: bluetooth BMS?

I have the xiaoxing bluetooth bms. But i have two 10s bms wired in series for 84v peak. Everything has been working fine for a while... but today on the way home... right at the end one batt cutout on low voltage... but i continued on for a little bit at low power i.e 30v and got the dreaded burning...

Justin 470 uf across ca input wire fixed it ! Like u said maybe low caps on controller was causing interference??? I put a 800ohm resist inline and problem came back ! So just left the cap and problem solved thanks !

Re: Cycle Analyst V3 preview and first beta release

Hi just tried the light plugged into ca and see video attached light doesnt blink ! https://vimeo.com/299527346 Also i dont think its the throttle wire that runs through ca as i ran an auxiliary battery pack to run ca and that is the only time ca didnt trip. For wireing its standard from the shunt. ...

Re: Cycle Analyst V3 preview and first beta release

Here is a video... whats wrong with this ca ? Voltage sags only to 22v from 24v and throttle doesnt even go yellow under load or cut out. Only the ca restarts ? If i throttle gradually it gets to full power 650w.. only when i do it fast it cuts out https://vimeo.com/299172587?utm_source=email&utm_me...

Re: Cycle Analyst V3 preview and first beta release

The thing is on the cav3 display voltage is not sagging below 22v. Also in the throttle that doesnt shut down it doesnt go red or show lvc cut out as it can. Its only the cav3 that cuts out and restarts when connected to main pack. If i run ca to a dummy 20v pack it stops this problem... it happens ...

Re: Cycle Analyst V3 preview and first beta release

But does low volts cause CA to shut down and reboot ? It has a throttle plugged in and that does not cut out hence i thought its the cav3 ? Do bms cut out so quick ? The thing is i also tried to run the main pack input of a 2nd battery with higher amp cutout and it still did it ? Hence why i was thi...

Re: Cycle Analyst V3 preview and first beta release

I have a cav3 running it on a 24v 500w motor and it has a strange problem the screen cutsout and resets and restarts and high load around 8-900w only. its not the battery BMS cutting out because I added an auxiliary battery in parallel to run the cav3 and it would not cut out when run like that. aws...

Re: bluetooth BMS?

Hi I have this BMS, but I am not sure if I have set the BMS values right as it seems to cut off early when one cell hits 4.2v but them immediately the pack stops charging and seems to end up under 41v. This is a 10S Lion pack so should charge to 41.5 to 42v . Is their something I need to change on t...

Is their anything newer or better than the 30Q 15amp cell or LGmj1 10amp cells

these cells are getting quite old and am wondering what better is comeing ? or are all the new cells 21700 format ?

I am struggling to find how to climb them with this kit. If I leave the power open to 5kw I find climbing super steep complex rough terrain uncontrollable. So I kept trialling setting on the CA to limit power but nothing seemed doable. The trottle is too twitchy. When you are on an incline maybe 20...

Re: Dave's 80:1 RC mid drive kit build log

Being clueless on the subject, how many "moving parts" are inside the gearbox that can wear down with time? Thats a good point, how do you repair or rebuild the gearbox and what life does it have ? i have seen the AFT kit gears last over 5000 km and then its a cheap $30 USD set of planetary gears. ...

Re: Help with mid drive selection and expectations

The square spindle is the weak point & will bend or break. I have no experience with the regular GNG kits but I do have an AFT 1680w, which I think is a modified heavy duty version of the GNG. I can tell you it was a big undertaking for me to get it right on the bike I chose to use, but now it's a ...

Thanks for the update. Awesome build ! also that's an impressive top speed 65kmh ! What is the peak current and power you see on the CA ? is the shunt calibrated correctly?

Re: Cycle Analyst V3 preview and first beta release

For a mid drive is it possible to hook up a hall signal wire to the PASS input wire from the CA to read motor RPM on a middrive on the CAV3 ?

Will the voltage and rpm values match ok to read direct of a hall sensor?
