Re: ordering bag from additives bike for uk

Anyone know where else to get one.

Thanks

Re: A123 18650 for sale

I think these cells have a capacity of around 900mah to 1100mah, depending on rate of D. I wouldn't pay much for them to be honest. The only reason I would have any interest in them is because I already have two large capacity 36v {12s} builds made from old 18650 cells which might need repairing ove...

Looks brilliant. I can attest to Luis painstaking attention to detail as I bought his old bike.

Re: Best donor frame to build an electric bike & getting started

My motor never seems to get warm. Ok the last time I took it out there was snow on the road. But it didn't get warm after 4Ah up some good hills. What I worry about is the effect of 4000w, in bursts. But there is no heat yet. The frame was an off-ebay, steel frame. I welded on some torque arms with ...

Re: Best donor frame to build an electric bike & getting started

I have a 12t MAC running in a 24" wheel and on a 6 fet controller of 16s Lipo hitting peaks of 60Amps and it doesn't get warm and the controller gets tepid after some hard ripping. The TRP brakes are great. I have them. I have a steel frame and I welded on my own torque arms too. Even with my Mac in...

Re: 6pence Resistance Spot Welder

In order to keep the welder simple, the amps are adjusted by changing the amount of the battery amps. So would the CCA of the battery be a better indicator of "weld power" than Ah? Most of the car batteries I have seen don't even have Ah ratings. Car batteries provide more wallop for far less time,...

Re: HK LiPo wiring harnesses

Is that photo with the 4mm bullets a series harness for two banks of LiPo or a parallel harness for two banks :?:

I am interested as I don't have time to solder and order wires connectors etc.

Thanks.

Hi,just a question about the lighting in your garage, I myself have the same problem, no lights in an underground garage.

Re: Can I Charge A Lead Acid Battery Using A Powerbank.....

Why are you so insistent on running everything through the lead acid packs instead of using your other packs directly to provide power for almost everything you need to do? Because big lead acid packs, when charged up, means I can get 3, 4, charges without having to worry about any other aspect of ...

There are people out there in so-called 3rd World countries who have solutions to these things.

I understand that energy can neither be created nor destroyed, and that this is an inefficient method of working.

Re: Can I Charge A Lead Acid Battery Using A Powerbank.....

I think you're going to have a bad time. A 16000mah Powerbank (16AH) will run at 3.7v. So that's 60WH, near as makes no difference. A deep cycle lead acid battery is typically 75+AH at 12v, or 900WH. So you'll need 15 Powerbanks to charge one of those, assuming full efficiency (which you won't get)...

Re: Can I Charge A Lead Acid Battery Using A Powerbank.....

Car jump starter/booster packs usually contain a cheap sealed lead acid battery of <18Ah. Connecting a charged LA battery to a discharged one will cause the latter to be partially charged at a slow rate. Trying to charge a large battery with a small one will mean you won't get much charging done be...

Hi folks. This is more of a prepper question than an Ebike question but its all interconnected.
