Re: Votol EM-100 & EM-150 controllers

Help needed please i received my votol em200/2, I hooked up the throttle and battery the first day the motor spun up, the next day i get into the programming with the USB plug provided and start messing with the 3 speed switch and changing a few settings, and i changed a few port settings now my th...

Re: Max charge current to have balance on?

Again nothing I'm telling you relates to the ANT. So you came to a thread asking about ANT BMS settings which you know nothing about, basic accused me of lying about the allowed setting range, all to “help” us? Lol Many of your cells there are just showing excess "surface charge" Let them...

Re: Max charge current to have balance on?

Recent studies show that batteries kept between 40-60% for a kong time can lose capacity and to regain it you drain to 2.0v and hold it for a day, charge to 3.65v and hold it for a day. If you have any link to those studies handy, please share https://iopscience.iop.org/article/10.1149/1945-7111/ab...

Re: Max charge current to have balance on?

Am testing the new version of the ANT BMS. Basically, if you aren't aware ANT has been amazing so far (to me at least) and then since the chip shortage their main chip went up x10 in price so they have changed it to a slower one and then have to redesign the whole app (which to begin with was probl...

Re: Max charge current to have balance on?

LFP is best charge terminated at 3.45V for longevity, if it settles back to 3.33V that is 100% Full You assume all LiFePO4 batteries have rhe same chemistry. They don’t. I have 4 batches that all settle out at differently voltages. Also charging to 3.65v/cell doesn't hurt them. With a small load th...

Re: Max charge current to have balance on?

My question is, why is it bad to have balance on when charging at say 20A? Why wouldn't it balance at any charge speed? I cant charge at 20a but ill see if it allows me to set it below my 2a charger and see if that stops all balance or only “charge balance”. My BMS allows me to set 0-50a in the “Ba...

Also im wondering if you know what method is used in SOC Methods 1, 2 and 3? I haven’t been able to figure it out.

So I just got my bike running with a qs138 v3, em-150-2, and 300a capable 20s lipo. In short, it’s massively underwhelming. It takes off from a stop so slowly. I was expecting a lot more power, even with stock settings. I can’t feel any difference when sport mode is on or off. I’ve installed a swit...

Re: I started a upgrade on a razor drifter.

So with these batteries I will only have 15 to 20 minutes of run time Yes, at full throttle, 1000 watts, 20a, you might get 15-20 minutes till it hits low voltage protection. And thats if you want to go below 50% depth of discharge, which decreases cycle life exponentially. I’m making a LiFePO4 bat...

Re: Votol EM-100 & EM-150 controllers

The specs are a bit unclear but the 55a is the busbar limit and the 190a is the peak phase wire current. Thats why you won’t find a time for peak as you would in a motor which has mass and takes time to heat up. If you exceed busbar current limit you risk letting thw magic smoke out of the Votol an...

It's not that easy to change the layout..... Because firmware 2.32 behaves completely differently than 2.33! Unfortunately, there are probably many more variants.....
