You smashed it here Andy. As someone who's used a Bafang BBSHD for the past 2 years, you're really tempting me to upgrade. Even to a Hub Motor. That torque you showed is something I've wanted for ages, when I saw it was in the second highest gear I was blown away.

Loving the bike chap, excellent work. May I ask how you deal with brakes? You seem to be running hydraulics, for whatever reason, my hydraulic system just boiled fluid when riding aggressively. I'm not sure what power I'm producing, it's 72v - peak battery output 50A (standard 20) the bike will top out at 47mph with a rear hub motor. But I'm a little confused how you produce so much power from such little batteries too. I have 2 36v batteries 10s5p connected in series. What kind of speeds are you getting?

Unless i'm understanding the kits wrong and just need to add the motor and electrics to what i already have and dont need to widen the back?

Aloha from Hawaii. I love your videos. I did similar with my bbshd but I have the sondors rockstar on the way and I’m interested in juicing the ultra it has to your specs. I generate a lot of heat maxing out the phaserunner on the bbshd and with the larger ultra I’m sure you’re getting more effective utilization of the power versus more heat. Keep posting brudda!

Also what's the biggest sprocket gear on your'e rear? Thank's allot for the vids, hope you see this

@andykirby 4 жыл бұрын

Voilmart is a hub motor isn’t it? Yes you can increase the power and increase speed by using a better controller like this but your battery needs to be able to provide the power, on hub motors 52V or higher battery gives you a better top speed.

@BuildProne 2 жыл бұрын

The cutoff was the same issue I was having. Your motor is drawing more current than your battery can provide so it is shutting off to keep from killing itself. Thats why when you turned the current up it shut off. For instance my motor draws 30amps max where as my old battery didnt provide 30 so if I revved too high it shut off

@andykirby 2 жыл бұрын

It's not a battery cutoff it was instantaneous phase current error on the phaserunner, they are known for this problem.

@chrisrathjan1501 4 жыл бұрын

Looks like each balance wire is actually connected to two cells. So the measured voltage of one cell is actually an average of two single battery cells in parallel. One of those cells could be really high internal resistance. So it is possible to overcharge one and not completely charge the other but appear to be ok as averaged. Ideally you should measure each single cell. It will probably be fine though.

I got an idea that it would be cool to get one of those phase runner controllers and the display so I could have a way to switch on the fly from my 48v pack to a small 72v pack in order to have a sort of electrical TURBO switch. I already have 39 Samsung 30q left over from my last battery build so, it wouldn't cost me much! .... Any suggestions as to whether this will work?

@andykirby 4 жыл бұрын

The best way would probably be to just use the 72V pack and then set the cycle analyst with two power profiles, one for low power (commuting etc) and another that unleashes the full power. A 72V setup tuned down will be better for the batteries than a 48v setup run at higher power (less amps, heat and no need for field weakening to reach decent speeds as 72v creates a High RPM anyway). Keep it simple 😁
