And that's why I don't like spot-welding them in place. I use compression clips so I can easily remove any cell.

Hi Folks, I'm running solar in my home, and am tied to the grid to back-feed energy I don't use. This works great for balancing costs, but still a slave to the grid. If I lose power, I'm still out. What standards are available for high-efficiency low-voltage applications for wiring a home...

Like I said, I've had a lot of luck running my 18650 (recycled laptops) batteries, and at only 2p was very stable and no hot spots anywhere. Checked with infrared thermometer on each and every battery. Now, this is with springs holders too. The new compression clips will carry significantly...

Right, that's why I keep all 12s in a single bank, so there will never be enough current draw to cause that issue.

Here's a photo of what I've got so far... I'm looking to build-in a 12s charge socket and Anderson power pole adapter right off the end of the pcb. This will allow me to build a box that I can slider the pcb into, and easily remove for charging or maintenance.

I've had much success with 18650 batteries. I'm developing a new 12s 2p PCB based off the following: http://www.aliexpress.com/snapshot/315573261.html These compression clips are much better than the typical spring clips as the compression clips place more force and has a higher contact area...

Hi Folks, I've had my starter motor replaced, and asked to keep the original part. I found that the only thing wrong with the motor was the brushes wore out due to oil getting inside. I was going to drop by the parts store and get a new set of brushes for it. I don't have a lot of options...

This is exactly what I was looking for! Good point on the geared motor. Reason I went with DD is for regen braking, but from what I've read, regen doesn't offer u much, especially with my li-ion battery setup.

Hi folks, Not sure how to classify this thread as it's more of a versatility question. I have a front wheel drive wheel hub motor and wanted to make it easier to detach for days I want to go powerless. The motor adds a slight resistance and I don't want to bike to far with it attached and no...

So I'm a little confused, because 36v divided by 4 is 9. 36v pack would be 9s wouldn't it? 12 times 4 = 48 so 48v would be 12s. So fully charged my pack reads about 51v. I would think u would grossly undercharge a 12s pack for a 36v system.

My motor/controller is 48v rated and accepts 52v fully charged battery like most 48v systems do.

Hi folks, I've built a 48v 12s 6p battery out of 18650s and am extremely happy with the performance. Now I'm looking for a simple way to charge and scale up as I am intending on going 8p soon. So I'm thinking a 12s 2p PCB BMS would be ideal as I link the batteries in 2p banks. I'm having a...

And so incredibly bulky too in comparison. Wanted something a little more inconspicuous. I find the numbers on the LCD screens a bit too small too. This one i posted is no more than an inch tall, but the display of the numbers are still larger than the more expensive units.

I'm not sure what you mean by less desirable. For me, I find those hobbyist amp meters far less desirable as the LCD displays are far to dificult to read at a glance while riding the bike. Not to mention glare and backlight issues. This meter is the easiest to read. Accuracy is not as...
