You can print the drawing out 1:1 on an inkjet or laser printer and then spray glue the back side and stick it to your sheet metal. Then use a straight edge and a scribe to etch the cut lines into...

    Charging my new thundersky pack

    I am not sure who made the cells. I heard TS changed names anyway. The cells are LiFeP04 and the TS cells were a different chemistry I believe. Do you have a part number for protection boards? Paul

    Charging my new thundersky pack

    Based on the input so far I may add a 6th battery and get a 36 volt charger. Its a shame I cant use the golf cart charger since it retails for over $400. I got it for free brand new with the rest of the parts so I will sell it here or on eBay and buy the 36 volt Lifep04 from elite. Paul

    Charging my new thundersky pack

    I just received 5, 20ah 12 volt packs from Elite Power Solutions that I ordered last week. I did not buy the charger they sell or the balancers. The total charged voltage should be 14.4 X 5 = 72 Volts. I am building a custom frame motorcycle based on the "Honda Solo 50" as my goal. I...

    Here is a link to the full specs sheet. Have a look and let me know what you think. Even at a slightly lower Ah rate I think $90 each is a good deal. http://www.shoraipower.com/t-battery-specs.aspx Paul

    I purchased 4 X 12 Volt 7 Ah SLA batteries from my local surplus discount electronics place ($10 each :) )and I wired them in a series for a 50 volt pack. I was wondering what the final charged voltage of the pack should be so I can verify it has a full charge? Thanks, Paul

    36 volt 12ah Replacement Battery Only for Switch Electric Bi

    I think the way to go with these is to plan on buying 2 and run them in parallel. That way you would not put too much stress on one pack. It would also give you a failsafe in case one pack failed you could keep going. I read several reviews for the bikes they sell and it looks like most...

    Mamba XL/Neu-Castle 2028 780kv Motor Combo 10HP!!!

    Here are the recommended gear ratios when running a 2.5 hp 7000 rpm 50cc motor. It looks like a 7000 rpm motor top speed would be 35 mph based on the gears below. My motor should be able to at least turn 18000 under load putting the top speed well above 60 mph. Obviously this does not account...

    Mamba XL/Neu-Castle 2028 780kv Motor Combo 10HP!!!

    Thanks for your comments. I will keep an eye on the motor case temp during static tests. So far its been only slightly warm during the 2-3 minute tests I've run. I just ran it again and I got around 900 rpm on the output shaft sprocket, so the input was around 16000 rpm. I really need to test it...

    36 volt 12ah Replacement Battery Only for Switch Electric Bi

    You can download the manuals from their web page. I was wondering what the difference is between "LFP. Prolly LMn." and Lifep04 is? The manual says "If the battery is regularly discharged and re-charged its life is about three years or 800- 1000 cycles or recharges (after which the storage...

    Target is a huge retail company here in the USA. They are owned by the Dayton-Hudson Corp. with thousands of retail stores like Wal-Mart.

    I have also been looking at electric clutches. They are used for PTO shafts from garden tractor to power accessories. I have seen several for various engine accessories also. I just don’t know if it would be worth the effort to convert one for the Staton gear box. I should receive my 5/8” ID...

    Looking around for an "organ donor" bike I found the cheapest one so far is a used Lefian LF200. Looks like an asian Nija copy. New they are under $2000!
