Though not affecting the charge any discharge is going to be unequal on the cell groups #1 & #10 as the final current discharge is converging/being directed to going thru one cell only. Once the battery charging issue is sorted I would try and alter the discharge connection. Ideally on the B-...

All I can think is either; 1. Charge fuse is blown on battery input line. 2. A bad dry solder joint. 3. The BMS is duff ?

Yes the soldering is quite messy, looks like you aren't using good 60/40 lead solder or enough iron heat to get nice fluid bright solder joints. The charge connector is the round one with thin wires, have you soldered the wires on correctly ? I assume so other wise it would have blown up. I...

The report indicates the women suffered minor injuries so I'm guessing the impact wasn't too bad initially but it is the after impact events, it is maybe where he has contacted something causing a fatal injury.

Hailong controllers are integrated in the battery base, they will be potted and use smaller solid state components so no extra wires to play with. If the the bike doesn't give a bit more speed with the display speed adjusted then the speed is programmed set in the controller. Afaik Hailong sell...

The finished item although a bit flimsy (has to be for lightness), is a quality looking finished item.

Rather then go thru the connection process of the BMS to the battery, it will be best if you show pics of how ; 1. You have connected the BMS , /B- & B+ to the battery. 2. The C- & C+ charge port/connector wire to the BMS and battery. 3. The P- & P+ discharge port/connector to the BMS...

Not looking hard enough, took me two seconds to find. https://www.pedelecs.co.uk/forum/threads/could-some-kindly-take-some-measurements-of-a-tongsheng-and-bafang-mid-drive.42860/#post-643551

Going back to the OP then generally the answer is yes, esp when it comes to the prices the mains stream brands charge for china/taiwanese made ebike as this is where most parts are manufactured. But as has been said if the market/buyer can stomach the prices and are willing to pay them then...

A bb93 is fine but the issue might be if the motor side casing of the chain ring fouls the rear stays. The bb93 is a uses std 34mm English thread. There are diagrams/drawings on the forum which have been posted so one will have to try the search section for them.

They are lithium - polymer pouch cells so no I doubt it. I bin them after I have dumped them in a bucket of water for a few days to kill them and make them safe.

I never throw stuff away until it is deemed no use, we can't ascertain any thing as the old connectors aren't viewable. We know the controller PAS B/R/W wire is Gnd/5V/Sig respectively so my gut feeling with the PAS is to go with Blk/Blk for Gnd , Red /Purple for 5v and White/Green for Sig. I...

Wow, one assumes he may have hit his head then or something quite dramatic.

Yes it is an uninsured moped, on three counts. 1. it is throttle powered and being used as so. 2. One is achieving well over the legal pedelec speed and twice the allowance. 3. The 48v BBS02 will be 500 or 750w rated and marked as so. You will find the first hurdle will be presenting it to a...

It was flynn who had a 10yo freego and he had no problem with the advice. Both of his threads, he was going to sell the bike as spares/repairs but the bike condition looked so good it was a no brainer to fit a new silver fish...

What is the motor rated at ? Is it limited to 25km/h ? 48v is legal.

You should be ok buying that battery and fitting it as I mentioned they come with the new fitting rail and base so if not a 100% match one simply swaps out the parts, it's not guaranteed the design remains 100% the same after 8 years or so. We had someone last year who had the same I think with...

When one looks at that so called prototype professional offering it looks pretty rubbish and harks back to the 80's and a kit car Dutton approach. This diy route has a far more satisfying look and appeal in a fully weathered velomobil shell. Ex foumite AK/Tony built this one...

It's a velomobil but still has to comply with pedelec laws or need registering if not. The market for them is a very niche one and only appeal to some cyclists who prefer the recumbent style. One needs to be quite dedicated and have very good riding ability to ride any type of velomobil on the...

A business will have a contract or regular courier they are on terms with and the issue of transporting battery's doesn't seem to be an issue, it is as a private individual they don't like dealing with even on returns. It's a one side deal where the businesses are there bread and butter...
