I know beauty is in the eye of the beholder, but those..........! Anyway, putting my personal prejudice to one side, those long stems on the ebay mirrors will likely lead to a lot of 'mirror shake' as you go down our less than perfect roads. The bar end mirrors are the thing to go for and Cat...

Hi Neal, I looked back to the discharge curves for the LG M50LT (care off Mooch) and I agree with your comment that capacity should be around the 8Ah So I popped down to the bike shed to look at my record sheet and durgh........ I'd recorded/measured 8.6Ah capacity NOT 6.8Ah as I initially...

OK @Nealh , thanks for that very useful backstory to your BMS experiences. I had spotted the BeMuchSafer Balance BMS and as you say it is slightly larger and needs a separate charging port. I was happy with both those aspects as it'd fit my battery pack and running out a charge port connection...

Hi Neal, ...has no balance feature... that caught me by suprise as I didn't know that but on looking further... well well! As said, I've just used that particular BMS in my first battery build but now I'm thinking I should look for a BMS that does balance - I like the common port...

I entirely understand your feelings towards cheap BMS and the problems they might cause - I had a BMS failure on my 10Ah bottle battery - it was a PITA in that I'd be out riding and .... no power. Sometimes a power off/on would work and sometimes not. The one I linked to was one recommend by...

There's Gumtree to consider but of course you still get people saying can I come and see it and then don't show, but from my own experiences, you get less people mucking you about than on Facebook Marketplace

'The instructions' - what were this instructions from - your tester/charger or something else? Seeing as you're building a battery pack with cells from a variety of sources (so the cells will have different discharge characteristics), using a BMS to prevent any one of your '4P' pack's from...

Have you contacted Cytronex Customer Services for advice yet? It might be a common problem easily resolved? I don't particularly follow postings about Cytronic kit as much as I might, but iirc I've seen postings of folks having connection problems of some sort that resulted in a 2nd...

Can't help you on that but I'd be pleased to hear what Cytronex customer service say / offer to do to help. In the past, Cytronex CS haven't exactly shone - maybe there's been an improvement?

Thanks for clarifying that point @matthewslack - I will indeed take care - I've worked on many high voltage systems (RADAR) and I'm here to tell the tale although the high energy density of lithium cells and what causes them to go wrong is something not to be complacent about. The chemistry and...

@matthewslack - thanks for your posts and all very useful in expanding my understanding of ebike batteries. I've only been into ebikes for around 18 months (but have an old skool background in electronics so hopefully not a complete numpty :rolleyes:) , and the BMS for the 36v 10Ah bottle...

Well remember on the reclaimed cell bit - as it happened I ended up with LG MG50LT from Fogstar wholesale at a great price of £2.99 each. (£4.14 at Cellsupply for new or £3.48 for reclaimed Sam 40T so Fogstar was a no-brainer).

Good to see a new kid on the block - let's hope there are some honest reviews coming along. They boast to be the best mid drive - best in what I wonder: weight, price, reliability, performance, availability of spares? - they've a lot to do to move the large fan based away from Bafang and TSDZ2.

The length of that pole is definitely in the "cyclist are getting to pi55 me off" bracket which might be OK for you but not the majority of us. If you need that much clearance to feel safe, maybe another mode of transport is better for you?

Well well, same age and history of AF as me and I'm just getting over the first ablation as I write and can't wait to get back on the bike - now where's my battery charger........ @Zlatan - I know that sometimes a 2nd ablation is needed - how long after your first ablation did it become...

This is not a question about the whys and wherefores of cell balancing as I'm well versed in the necessity of this. What I am looking for is in two parts: 1. I've got a bunch of new cells ready for my first 10s 2p build and will be measuring the voltage of each cell and 'pairing up' the cells...

My AF is triggered by strenuous cycling so I avoid doing that via my 250w TSDZ2 - best thing I ever did for my cycling.

It is very difficult to get much data on what is the likelihood of such an incident. If the number of incidents does increase and the problem is identified as being down to the charger (rather than the battery, wiring or controller) then that's when you'll see at least from reputable...

Yes, possibly a spoof video maybe set up by the 'wearing a helmet saved my life' brigade. Mind you, if it's a genuine incident, the rider probably was pleased to have his skid lid on. Yes Andy, Magura HS33 - they're on our tandem and we've toured a fair bit with full camping kit and the Maguras...

Andy, what are we looking at here? It just looks like the rider hit something and went over the handlebars. I use v-brakes on my bike - more than edquate power to stop (as in I have to watch out to not lock the wheels if I apply too much squeeze). I have had hydraulic disc brakes and they are...
