    Also, AliBaba claim they have LG Chem E63 Cells: https://www.alibaba.com/product-detail/new-rechargeable-battery-chem-e63-for_62426011491.html 60AH Packs. These would be great, but no idea on authenticity. I asked them, they said they're genuine, no surprise there. But I can't find any direct...

    Building Electric Moped. Battery Questions

    Very interesting suggestions thanks Chalo. From the looks of things, I can fit 200 x 21700 @ 4850 7.3A Cells in the case so the options I have are: 48V: 13S 15P = 73AH & 110A 72V: 20S 10P = 49AH & 73A I'm leaning towards the 48V Build for simplicity and convenience. Here in the UK, there are...

    Building Electric Moped. Battery Questions

    Enduro frame. https://imgur.com/a/ljLWAGv It says it has a drop out of 155mm. So I'm thinking the maximum I will ever need to go as a registered motorcycle is 50MPH So any motor that could do that and I guess for the time being I can just limit it to meet UK regulations for a moped and then...

    Building Electric Moped. Battery Questions

    Oh right. I have been getting a bit confused then I see. So even using a 10, 20A controller would be fine too then as an example? As for the BMS in regards to ever wanting to upgrade the motor in future. If I buy a lower-rated BMS say 40A then I want to upgrade my motor to 2kW or 3kW in the...

    Building Electric Moped. Battery Questions

    Cheers. Thank you. Since I'm thinking I may actually use a higher wattage motor than 1.5kW just in case I ever do decide to take it off-road in the near future or if i decide to register it as a full motorcycle instead of a moped to go faster than the restricted 30MPH and I can always just...

    Building Electric Moped. Battery Questions

    Thanks Chalo for the updated post. In regards to weight and maintenance do you believe that 1500W is a great contender. Have you ever needed to reapply lithium grease? Is it easy to maintenance basically? I would ideally want something with common parts, easy and accessible screws and easy to...

    Thanks for the suggestion. But I will want to bring it indoors and that may be a bit bulky but that's a great suggestion that I will pass on to people. Thanks :bigthumb:

    Building Electric Moped. Battery Questions

    Thanks for the above replies. So, yes I do believe I was getting mixed up between A and AH. I would want to use these cells now: https://eu.nkon.nl/rechargeable/li-ion/21700-20700-size/lg-inr21700-m50-5000mah-7-3a.html It's an LG 21700 with 7.3A Discharge and 4850mAh capacity. Can you tell...

    Building Electric Moped. Battery Questions

    Oh as in I actually wanted to make a 60AH battery you see so that's the example. Since I will be doing a courier job and need to go up and down all over that was the worry you see. I am sure I can get it to last though at 1500W reasonably but wanted to be on the safe side. Typically how much of...

    Building Electric Moped. Battery Questions

    Thanks for the reply 48V x 60AH = 2880W Motor = 1500W 2880 divide 1500W = 1.92 or 1hr 55mins of continuous throttle in perfect conditions which I'm not sure is going to be enough for me. In the City of London UK, speed limit is 20 and on certain areas can peak 30 but rarely where I am at. I...

    Building Electric Moped. Battery Questions

    Hi, Thanks for the reply. Currently just an IT student and needed an efficient electric/moped for uni/work since I'm in London UK there's congestion charge for any fuel vehicles at £15 a day in the city in most areas, electric just eliminates that problem. I thought the way it worked was like...

    Confusing electrical issues on my e bike

    What is using the DC-DC converter the Throttle or the Lights or both? I would've assumed the throttle connected directly to your E-bike controller. It could be an issue with the controller or the throttle. I would disconnect the lights, DC-DC converter too if the throttle doesn't use it and see...

    Building Electric Moped. Battery Questions

    Hello, I want to build an electric moped/ebike to get it fully registered using the Enduro frame. https://imgur.com/a/ljLWAGv Since this will be used within the city. It only needs to reach a maximum of 20MPH most of the time and 30MPH in certain areas. I realise that I will need a hub motor...
