Re: Splicing/ connecting charge wires to battery

thanks. I am looking for the Andersons locally, will look for the others as well. I kinda doubt you'll find them locally (at least for a decent price). I get mine from Mouser . I can get the connectors below (or any more suitable on their website) with 1 day delivery. With items from the USA, I can...

Re: Splicing/ connecting charge wires to battery

How have these wires survived 5 years? Also, I was intending to get a 24F Nucular when available, to have no stress on the controller. This uses 8AWG wire - but yet 300A battery max? Because unlike connectors, wire doesn't fail until it fuses -- it just gets increasingly hot and lossy. Wire current...

Re: Splicing/ connecting charge wires to battery

I have ( a few of) the same controller but it is 96v, 55A, and the wires are much larger.... 10mm^2? Somewhere round there.. Just like the gauge of a QS205V3... SAme gauge as my Lyen 24FEt, or maybe a tiny bit less. Aside from that, looks identical to your 48v 70A. I have opened it and it has big s...

did you consider the specs are bullshit?
Do you mean the ZL controller? It's possible, but it has been running at 60a max with no issues?

and... I have no idea about the Nucular

Re: Splicing/ connecting charge wires to battery

the plot thickens... the controller I am using has wires to the battery much less than 10AWG (3.4mm2). It is rated at 70A (I have been running at 60A max via the CA). The wires have no "AWG" markings I can see. This controller was used with my previous 22S5P 30Q battery. How have these wir...

what do people use to run 80 amps plus - XT150s, or it there an alternative?
Anderson SB connectors, or QiangShui QS8-S if you need anti-spark

compare an SB50 with a XT90 and tell me the first thing you notice.

bear in mind that the SB50 is rated 35 amps (aka: basically half!) LOWER then the XT90....
I guess the sheer size and quality of the SB50....

Re: Splicing/ connecting charge wires to battery

you bolt connections with pressed on (so no solder!) ring lugs. if you have to takr them out often you use a single xt60 or whatever that only does the precharging resistor and then real (so no chinese) SB75 or bigger anderson connectors so you dont damage the connector or kill the controller with ...

Re: Splicing/ connecting charge wires to battery

"It is 8 mm by 0.2mm makes it 1.5 mm^2. I tested with 25A through it and the temperature raised from abut 20degC to 35degC in 15 minutes. Something tells me he didn't test it in a closed box. Closed case means less heat rejection and higher operating temperature. Which means higher resistance ...

Re: Splicing/ connecting charge wires to battery

The reason for the parallel wires is so I can run maximum 100A from the battery (80A max continuous)

Splicing/ connecting charge wires to battery

I have had a new battery made, 22S5P Samsung INR21700-40T. battery 0.jpg The guy that made it didn't include charge wires. The wires are 2 sets of 10AWG wire. However, I would like to have an external chargepoint, as the battery is in an enclosed frame (i.e. not have to unplug one XT90 set to charge...

I have installed a CYC X1 Pro on s Surly Moonlander. However, the controller and wiring is very exposed. Has anyone come up with an easy way to make a cover? I could try and do a 3d print, but there are zipties in the way. I had an idea of using a polyester casting (as in used for a broken arm cast)...

What's the peak amps of your controller? you're very likely hitting LVC from voltage sag.. the 30Q isn't the strongest cell. Like, a realistic continuous current for your pack would be 36A ( 2C ) or less.
the controller is 70 amps, the bms 90 amps, CA sets max amps at 65

Re: why did battery cut out?

went for a ride over the weekend. The battery is a 18S6P 30Q. Battery was fully charged at around 74v at the start. The ride was very hilly, and I wasn't pedaling along (torn achilles at the moment). Regen also wasn't working - I am normally very reliant on that for braking and some regen. At about...

Re: E-S Stealth Electric Bike Owners

Those are same grips I put on my wife’s specialized which I built with a Bafang BBS02 motor. I just thought since it’s twist throttle you wouldn’t want that shape for twist. Very comfortable grip. Especially downhill I use a half twist throttle (not a full twist) so the relative motion is very smal...
