Re: Battery Clearing House

A few weeks ago, I bout a 100+ SPIM08HP from them. They came in two boxes with no bubble wrap and no protective shipping measures besides the 2 boxes they came in. I literally spent hours and hours trying to straighten the terminals out (click link below to see a video and some pictures that I prov...

Re: Battery Clearing House

Never buying from them again. https://drive.google.com/drive/folders/1E7bgGbxKzkBvIHm7e5A7g1guDpsVqqsP?usp=sharing I'm going to buy the 70 pack of SPIM08HP when it comes back in stock. For $2/cell as long as most of the cells are still around 0.8mo...

Re: Building A Ludicrous 14s2p SPIM08hp battery

I've been pretty busy with college for the past couple days and have finally finished categorizing my battery pack. I will be using 32 cells to make a (mostly) 2S14P pack, with 3 cells on 4 of the parallel groups because they have weaker cells. According to my measurements and calculations, the fin...

Re: US Malectrics Spot Welder Owners! Questions!

@thetailwind: I purchased mine just before the holiday's and it took ~1week to get to me. Let me tell you, this thing is awesome!!! I will never go back to soldering cells again.

Re: Regen current through BMS

The first thing to ask is: When you are regen braking and the battery is full, does the braking action cut off at all? If not, then for whatever reason the BMS is definitely not cutting off (whether it "should" or not might be another story, depending on design/hookup). As for whether it ...

Re: Controller shunt mods

how come when the bike accelerates from a stop it draws peak 40a but when you accelerate from say 15 mph it draws less? Is it because the phase current is lower than the battery current?

Re: new cyclone 3000 w mid-drive kit?

Anyone know how to fix the throttle? I have the stock non bluetooth 40a controller and the throttle response is terrible because it's speed controlled not current controlled. Do I need a new throttle or is there another solution? It's manageable on road but not for steeper technical trails. If you ...

What throttle are you using? Maybe give it some time to get used to?

nah I've had it for a couple months now. I had no trouble adjusting to other throttles. It jerks really hard on startup no matter how slow i go

Re: Phase current VS Battery current...

if input power (battery to ESC) is equal to the output power (ESC to motor), and the Phase Current=Wattage/(%PWM * Voltage), then wouldn't the phase current have to be infinite when the speed (%PWM) is 0?

Re: Cyclone 3000 un-smooth throttle response

get a current sensing speed controller. It's most likely not the throttle. The stock cyclone controller is speed controlled and has terrible throttle response

Re: GNG X1-pro 3000w

better to have somebody with a lathe. The axle and the thread have about 0,2 mm difference, which gets bigger and bigger with every acceleration. A thread is never that strong than a even metal. There are plenty of adapter for the BBSHD, you can use them. But the motor will be pressed to the adapte...
