Thanks for your reply. The voltage isn't dropping faster than normal. Once I am depleted below 51 volts, I risk my setup shutting down if I draw too many amps. By the time I deplete to 47 volts, that risk is much higher. And by "risk drawing too many amps," I mean that drawing 20amps is safe...

Hey everyone, I'm looking for some advice. I have a 14s, 15ah li-ion pack, and within the last week my setup has been cutting out. My CA2 will show the voltage dropping quickly, when I release the throttle my regen breaking kicks in and it will power back up. This has never happened in the...

Thanks for all the input. I'll open it up and post a pictures just for the sake of learning a thing or two, but chances are I will go ahead and cut the connectors so I can solder up this other charger. I'll try and run the bike at lower amps in the hope that the cells don't get too unbalanced...

I mean zero volts. Here is a pic of the charger. It came with my em3ev battery. It's the LT250-14m-3s.

Hello Forum, My 58.8v charger just blew. My guess is the fan stopped working and the unit overheated because the garage smells of burned electronics. I did check it with my voltmeter and the charger is definitely fried....reading all zeros. Another thread suggests checking the fuse, which I...

Hmmmm. Never knew that. I got this controller from em3ev when I bought the battery. Here are the specs... Specification: • 12pcs of Genuine IRFB4110 Mosfets. Just about the best 100V TO-220 Mosfet available • 100V Caps, Max input voltage is limited to 90V • 36-72V operation, 90V max • 40A...

Well I found the problem. It was extremely obvious after I took apart the bike. In my excitement of setting up my new system, my dumbass forgot to remove the water bottle cage mounting bolts. There is not much padding on my triangle bag down the seat post area and everytime I hit a bump those...

I'm more confused than ever. After my post here last night I went outside to disconnect the battery so I could take voltages and post pictures. I decided to give it one more shot at a charge....and it worked. I didn't knowingly move any connectors or anything. Just plugged 'er in. I tried at...

Ok. I'm going to take some pictures in the morning of my battery and the charger to post. Here are some answers to the questions asked. Thank you for helping. As an fyi....I did send an email to Paul (Cellman) at em3ev.com...just waiting to hear back from him. Amberwolf, I'm embarrassed to...

Well I'm having another problem. I let the kid run the bike pretty hard over at the park today...which means bumpy terrain and definitely involves a lot of stopping and then full throttle...ie a lot of high wattage running. More continuous high wattage than I ever do riding on the road. All of...

Well, I'm back up and running. It was a phase wire....almost completely severed. Not sure how it even happened because everything is very secure in my triangle bag. Does soldering wire make it more brittle? My soldering technique still needs work. Haha. I was close to missing the problem...

Glad I asked first. Will do. Thanks.

Thanks everyone. I found a phase wire almost severed off at the gold bullet connection on a phase wire. I just ordered new connectors, but I picked up these at radio shack for now. I doubt they will carry amps well. Are the OK to use for a week or so and can they somehow do damage??

I'll have to take a good look at the connections later this week. I'm really hoping I don't have to order new hall sensors. For some reason I never seem to get online orders in a very timely manner. Wesnewell, you don't happen to know what hall sensors our 1000w yescomusa motors use do you...

Much thanks. I did read up on similar symptoms and a few people did diagnose hall sensor wires and were able to fix the problem. Fingers are crossed that its just in the connectors and not a bad hall sensor itself.
