Since I started using meanwell led drivers as chargers I've not looked back to the bad old days of chinesium . Controllable current and voltage, waterproof, no fans and very well engineered. Normally 10v varience but I've seen them adjustable from 12v to 60v. There are too many different...

I have these (clarks m2). They always brake well but they annoy me a lot. The disks always touch a bit somewhere, despite following all the youtube adjustment tutorials I can't stop them touching, I think I sometimes bend the disks when taking the rear wheel off and on and can't get them...

>So, if there is differing resistance then this can't be a good thing once a >heavier load is put on. Checking I guess for voltage is one thing, but current >and resistance is another. I'm pretty sure one cell isn't making contact at all in each of those 3 parallel groups. That's why the...

the groups at 4.12v all have a cell that isn't contacting properly. Take those groups apart and fit them pack together ensuring good contact. The cells should discharge into the lower voltage cell. leaving all cells in the pack at 3.95v. When you reach this point. Put them on the charger...

Great photos. Perhaps dialectic grease would be useful on spade terminal like it is on car batteries. It's counter intuitive because grease is an insulator, with car batteries it works fine because the metal on metal contact pushes the grease out of the way giving a good connection, whilst...

Cutting up one of these and connecting one end to the Satiator could do the trick. https://www.e-bikeshop.co.uk/eBike-Spare-Parts/Bosch-Charger-Adaptor-Classic-Performance If don't need the high charge rates of the Satiator and wanted a cheaper option you could use a meanwell led driver power...

Thanks for the generous offer. I've sent you a PM

Ping will build you a battery to fit an existing case http://www.pingbattery.com/ or here https://em3ev.com/

https://cdn.shopify.com/s/files/1/0674/3651/files/LG18650_HE4.PDF?828 Nice high power cells. I don't have a spot welder or lots of chargers to catalogue the capacities so I wouldn't be much use to you. I think the next I'm going to be building I'll might try these clip together battery...

What kind of lg cells do you have?

After a long break from e-biking I recently got hold of a second hand Kalkhoff Pro-Connect with a 24v Panasonic drive. The bike has so far been working well and I've been making lots of modifications and repairs. I've taken off the motor/housing to reroute some of the brake/gear cables and...

I find any disc brakes give you more control, but perhaps that because I was not in the habit of adjusting my pads all the time. Disk brakes are definitely better in the wet.

I have hydraulic brakes, I don't think the breaking is any better than mech disks but the modulation is better and they feel nicer to use. At routine speeds of 25+ mph suspension will save a lot of bike wear joint wear.and also might save you from coming off the bike. It's quite a different...

Hi Flecc, haha yes its been a while. Nice to see the forum growing and doing well. I been away from ebikes for a good while now living in the city centre with everything really close and also somehow learned to love pedalling up the hills :eek: Still I know I'm going to build a new ebike...

Astroflight 112D 40 cell charger. Will charge any nimh pack from 1 cell up to 48 volt or 40 cells. It terminates on Delta peak, and so bypasses the need to use the pack thermistor. For more complex specs see the link to the manual below. It runs of a 12 volt PSU or off a car battery...

check the ratings of the main components in the controller, it will give you some idea.. Don't exceed the the capacitor ratings by more than a few volts. Run the bike with the controller exposed indoors and check for anything heating up or behaving oddly. For example I've found the powabyke...

No advantage over standard sealed lead acid batteries (they're not any lighter). There only advantage is their power output. 900 amps each, so if you used two in series you could have 24 volts * 900 amps = 21600 watts. which is 86 times the UK road legal limit:eek: So you could go very...

Hi Paul, Just to add. You might find soldering to the xlr connectors or ntc connector pins a little tricky (i did:D ) In which case I'd recommend getting an xlr or ntc extesnsion cable and then soldering the wires from the pack to the extension cable. Microphone cable XLR plug - XLR...

Basically its not necessary to this, unless you for some reason suspect your 3 batteries to be unbalanced for some particular reason. The advantage of charging each 12 volt battery with an individual charger is that each battery is always charged correctly. Over time if the individual...

no it's not. Interestingly though, I've heard of many people either smart chargers or 3 individual 12 volt chargers in order to extend cycle life.
