Re: Cycle Analyst V3 preview and first beta release

Thanks for the kind words - glad you find the posts helpful :D The values you report for the halls suggest all three are toast. But - this may instead be a matter of test technique. If you search ES or go to the ebikes.ca site under 'Learn'/'Troubleshooting' you will find some help on proper proced...

Re: Cycle Analyst V3 preview and first beta release

... the speed sensor stopped working.... Any updates? I you have a viable alternating hi/lo signal on the Speed input and are getting no speed reading, I afraid you may have shot phase voltage into the CA and smoked something. There's only a diode (D2) between the SPD input and the processor. The d...

Re: Cycle Analyst V3 preview and first beta release

The speedometer output reading has stopped working on my Cycle Analyst, and I'm trying to track down how to fix it. This is actually a CA 2.4, but it's relatively new, so I suspect the board layout is similar to a CA3. Recently I had an issue where the side plate rubbed the housing off of a phase w...

If you take the money out of your lottery tickets budget, I’d say chances are better.

Re: Help setting up Sabvoton and QS-205

I’m 99% certain it’s due to your ignition wire. If you don’t power cycle via the ignition wire, the parameters won’t save (stupid, I know). I learned this the hard way also. Makes sense in hindsight. If power is not connected to controller, how is it going to power the save on the logic side? We ne...

Re: So confused, please help (24s 99.6V battery charging/safety)

My two cents. Nothing really wrong with the existing charging methods, provided the meanwells are set to the right voltage. (not overcharging) You might consider tuning them to very slightly undercharge the pack, if your needs don't require the entire capacity very often. Using those 4s balance plu...

I’m pretty certain I’ll be using the cross-platform Mono framework to send/receive bytes through serial. This will ensure multi-platform functionality and should provide a rock solid assisted command line base for the beta version.

Re: So confused, please help (24s 99.6V battery charging/safety)

You can also charge/balance with rc chargers. Very easy and safe. I thought about that, but the way the 24s pack is set up, I’d have to plug the entire 24 cells into the RC charger since many (or all of them?) require the +/- of the pack plus the balance JST. Wouldn’t I blow most chargers up by doi...
