Interesting. Didn't know there was a 3 mode version. The one I got from Geoman is the 5 mode version. I am taking the light off of my handlebars and putting my old blinky walmart light back on. I ordered the headstrap from Geoman and extra long cord so I can plug into my power supply. I love the...

I am currently using a 60V 10A autoranging power supply built by HP/Agilent, model 6038A. I got it for a song on Ebay, but the original price was a couple grand. For the specs you are wanting be prepared to shell out some big bucks. If you find something for less than $500 let me know too! They...

After my first real night ride with a Walmart special headlight, I cleaned out my underwear and found the reviews for the Magicshine. I just installed the lighthead that I got from Geoman, and was wondering if there are any lurkers out there that have come up with a clever way of mounting it...

Yep, bad cell. Hits cutoff after 12.3AH (even at around .5C). Tore apart pack and verified on terminals. Dumbass..could you still post those pics? They would still add to the thickness of my pack but would be a few mm thinner than the 40AH and I think I could work with them.

Appreciate everybody's help. Here is where I am at the moment. I still may have a bad cell but doesn't seem to have anything to do with my original problem. I have had BMS cutout problems with my cells around 12AH discharge since I have built the bike. I have installed BM6s on my cells which are...

Hiya Methods, Do you have any info on the cutter and spoke supply you mention? I have been thinking about going back to my lbs to have them relace my wheel into a 1x cross pattern. When they originally laced my motor up for me they used a 2x pattern with no dishing. Getting close to 800 miles...

Russell, Thanks, that is what I was looking for. Had found another that looked just like that (forget where now) but the spec sheet said lifepo4 with a max working voltage of 4.25V. Maybe a translation error on the battery type or voltage, either way I kept looking. Dumbass, don't want to put...

Ahh, wow, no can't REALLY use a 4 pack, but I sure as heck would buy the pack just to tear apart and use one inside for that price. Any idea of the cells measurements inside?

Got a cell that is apparently weak (either that or discharging through my BMS). Anybody got any recommendations for where to get a single 20ah prismatic (rectangular box) cell?

I have been using the washers with tabs (the tabs rest inside the dropouts) and they seem to work fine (about 135 miles/week) have close to a 1000 on them now, but the problem is I am starting to get some axle creep. Long story short, I saw your posting and it got me to thinking about buying...

Writing up my experiences with getting this baby going but here it is in the beginning: and after 1000W GM with 48V BLDC Regen Controller +48V20AH 16S prismatic pack. Custom built an aluminum frame with plastic battery holders in the rear panniers that actually are holding the weight.

I won the first auction of Mr. Chan's where he had switched to prismatic cells (before I found this forum) and was nervous when his account was suspended on Ebay. The reviews here made me even more nervous but just crossed my fingers and hoped for the best. I received the battery (48V20AH 16s...

Greetings E-bike Masters, Very much an E-bike noob here on his first build, but hoping to contribute in the future. (Have pretty much read a good chunk of this whole forum, following the design of the controllers with mucho interest.) Can anyone with a rear GM tell me whether there is a...
