Same pack, same configuration, I rebuilt the modules so instead of 1p 16s they are 2P 8S with a connector on each module to Check them easily. 16 model S BMB’s onto a custom BMS to control them. The modules have 4 10k thermistors so comparable with the Tesla BMB’s but obviously only room for 2...

If the motor is anything like the EM-1 then you may find little increase in going to a slightly larger pack. The motor is saturated already and you just warm up the motor and see a little less voltage sag. The actual controller is okay, not the best but not the worst. The swapping the motor out...

Maybe you can look on the diyekectricar wedsite, they have a comprehensive classifieds abd there are a lot of used motors there.

Did you look any further into the conversion. i have teh P85 motor and inverter on its way along with the controller. The batterys I';'m going to worry about after I have the motor installed. I assume driven conservatively I should be able to go for short drives, not that its being built for...

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. Tesla have started implementing charges at their Superchargers if you are not...

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. The problem is the...

Why not the Luna mini and turn down the voltage to suit, I turned up my 48v to charge 52v pack. https://electricbike.com/forum/forum/knowledge-base/chargers/38871-how-to-adjust-the-luna-charger-mini-and-advanced

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...

80v is an actual reading or just indicated by the bars? you need to see what you are drawing by using a cheap meter https://www.aliexpress.com/item/Battery-Tester-TK15-High-Precision-LiFePO-Lithium-Lead-Acid-Battery-Testers-Coulomb-Counter-50A/32823138463.html?spm=a2g0s.8937460.0.0.m7wCsB...

I got a luna advanced charger about a week before I decided to go to 52v and dropped the money on a Satiator and I am glad i did, I have a 72v pack now along with 65v pack and its so convenient to use. And silent

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...

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. I'm hoping the collective...

That controller looks suspiciously like the daymak em1. i would go for a recognized controller rather than one of these. That just my personal opinion though

If you have the stock tires that are designed for e-bikes that will throw your balance out at those speeds. Fortnine.ca are pretty good at prices and delivery

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...
