Re: (Toronto) Need ebike help, regen braking issue

What controller are you using, some of the cheaper items simply do not have regen (from experience very frustrating). Do you have a brake light or some type of activation for an input for the regeneration.

Tesla slave BMS

A quick ask around for all of the people breaking down tesla batteries to cells. Do you still have the slave BMS's, if so I'm interested in buying some for a project I'm working on

Re: Add your EV etiquette tips for the newbs

So if a car is fully charged and sitting in a parking spot your saying don't unplug, I have a sign on my car stating to go ahead if I'm charged, but my car also tells me when its fully charged so i simply move my car.

Re: 52V bms

your best bet is (choose the shortest delivery time from China here) and just make sure you do not undersize it otherwise it will cut out going up hills) trust me I thought matching to my controller was smart at one time, much better to match the output potential of your pack.

Why not the Luna mini and turn down the voltage to suit, I turned up my 48v to charge 52v pack.

Re: Ebike (lead acid) stored over winter in un heated garage question

If they were kept charged the freezing point is something like -60 c. I don’t believe it got that cold in Toronto this year. However batteries don’t like being cold hence the huge reduction in CCA in car batteries, even worse in the SLA batteries, try a few charge cycles and keep it plugged in if yo...

Re: Tesla PEM heat sink material required

The problem appears around 40,000 or 5 years. The answer is a remanufactured PEM at $10,000 that has a 3 year warranty. They simply replace the compound. The goal for them it seems is to get people to upgrade to the 3.0 battery pack with an upgraded PEM that uses better quality IGBT’s. If a solution...

Okay, I have a tesla roadster that has the well documented PEM failure The answer seems to be replacement of the thermal layer under the IGBT's https://teslamotorsclub.com/tmc/threads/roadster-pem-failure.88028/ But there is little conclusion as to what that may be.

Re: Unlock speed with lcd display

None of your links actually work so its a little hard to know exactly what you have. your guess is correct the controller will be the only way to unlock more speed (that and a lot more pedaling) but you are probably expecting a lot from a 36v 500w motor with an 8Ah battery. that will assist your ped...

Re: Mid drive vs Hub Motor for 10000 watt project

I’m with the controller to. Your battery is 3 times better than mine and I get easily equal your performance. The motor will do 75 km/h with 72v so any of the proven controllers (Kelly, power velocity, sabvoton) would probably do what you want. All should plug up to your CA. I wouldn’t go charging t...

Re: Mid drive vs Hub Motor for 10000 watt project

Something sounds wrong, Is the CA verifing your voltage/Amps because I would expect the increase in voltage to be pushing closer to 60km/hr. Its a super heavy bike but so are a lot of DUI scooters and they are going 60km/hr for 50km with pretty much an upgraded controller and good battery reserves a...
