Thanks for this info! Finally was able to spot weld A123 cans tonight! https://endless-sphere.com/forums/viewtopic.php?f=14&t=110637

May 2014, I bought 220 pcs of A123 cells straight from the factory for my second e-bike, the price was good, and I had some extra cash. Later, in 2015, I bought JP welder kit, serial number 2-1. After soldering 2 packs for my first e-bike, I knew there's got to be a better way. In 2017 I got...

What cost? I leased 2017 FFE 4 years ago, $250/month, after 57,000 km of city driving I had exactly 2 problems. Dead battery in the key fob, $1 to replace, and last winter, dead 12v battery. I didn't even bother with Ford warranty, because it happened on the weekend, just replaced it myself...

Apparently, he really liked idea of 2 wheeled electric vehicles. Few years ago, he got ebike. And recently, he got 27 hp Recon, which looks like cheap clone of Vector. Which he crashed few days ago, breaking his back in the process. His advise? RTFM...

I never watch anything more than 1 or 2 minutes long on youtube. Site became way too commercialized, with click baiting everywhere, and other crap. I can't stand it. As for the "girl", who's obviously "social media influencer", or whatever they are called nowadays, she's just trying to make...

I wouldn't hold my breath. Unreliable BMS's was exactly the reason why I avoided them in 2013, instead of using it, I ended making my own charger and balancer for my pack 7 years ago. Well, come 2020, not much has changed since then. Granted, BMS I got is def step in right direction...

3 years ago I bought new electric Ford Focus, and parked my ebike for good. But things were already getting sketchy in Toronto for ebikers. Too many idiots riding these stupid scooters all over the place. Sidewalks, drunk, no Dl, etc. Now I see guys on these things easily going 50 km/h in the...

Behold, completely solderless ghetto design! I somewhat screwed up my spot welder built, now waiting for the Pickit programmer to fix it, meanwhile my new BMS was already here. I've decided to make temp 24S1P pack to test it. Since A123 26650 are aluminum, I came up with the following idea...

I agree. However, I'd still prefer to use balancing charger or BMS during first few months of using new battery. I finished recently my 1 kW charger with built-in 100A BMS for my 24S6P A123 26650 battery.

Well, I'm glad to inform you guys, but James from lithiumbatterypcb.com came thru. He shipped my order on Monday, May 11th from HK by Fedex Express, today, May 13th I already had it in my hands by 10 AM in Toronto. 24S 100A BMS with BT and PC module, full box of plastic 26650 holders, I didnt...

Wow, 30 years, eh? I didnt have anyone to teach me, but thanks to the magic of the internet, now most of the info is available online. You just need to take your time to find it, read it, or watch it. My front 16" wheel for project #1 was somewhat easy to do, since there's more space between...

Bicycle wheels. In 2013 I was trying to avoid the whole D.I.Y. wheel building routine for my first project, and went to my fav local bike shop in Toronto, 5 mln. people. Staff there was always super helpful before. "- Ah, excuse me sir, I'm gonna need you to lace this front wheel bicycle hub...

Oh boy. At least Im not alone having this problem with lithiumbatterypcb.com. I've sent them RFQ on April 19th, and by 23rd everything was good to go. They were replying fast to my questions, between 24 and 48 hours. Ive paid their Paypal invoice on 23rd, and was told my order will ship out by...
