    How can I convert my old battery pack to use as power source when power goes out, like for a light, little fan etc?

    Found them, thanks :)

    How can I convert my old battery pack to use as power source when power goes out, like for a light, little fan etc?

    I have a pack of Lifepo4 cells, still like new, just a bit bulky and I don't do the long ride I originally purchased them for so was wondering how I'd go about repurposing them to use as a power supply, just for some things like a little light, small car type fan etc? We are in hurricane season...

    How much power can I get out of a 36v x 30ah battery pack, for electric motor on inflatable kayak?

    Oh, this is a similar kayak with a 30lb thrust motor moving along pretty good https://www.youtube.com/watch?v=lha9ONDYJu4

    How much power can I get out of a 36v x 30ah battery pack, for electric motor on inflatable kayak?

    It's a coleman 2 person inflatable, they don't make it specifically anymore, it is 11ft long, not aerodynamic at all but not tipsy and can really stretch out--especially with an electric motor. The design like in video for motor support, since I have 36v of cells I might as well get a 36v...

    How much power can I get out of a 36v x 30ah battery pack, for electric motor on inflatable kayak?

    I haven't been using my electric bike as much lately, been enjoying pedaling when I do go which isn't as often or definitely not as far as when I built the e-bike; the batteries are the prismatic cells, like new; thought they'd make good batteries for an electric trolling motor on my 2 person...

    New Electric Velomobile In Town - Virtue Pedalist

    Hmm, that's a good point; Once riding my bike carrying one of those big art portfolio cases a wind hit me almost hard enough to knock me over, so that does seem like an issue, high and narrrow is generally a formula for tipping, wonder what the designer has to say about that. Otherwise I like it.

    Question about putting a larger lipo battery in child's rc car?

    I just don't want the possibility of it catching fire for a bit more mah; would an 18650 be safer?

    Question about putting a larger lipo battery in child's rc car?

    Oops, had meant I ended up going with lifePo cells for my e-Bike instead of lipo, not about the rc car.

    Question about putting a larger lipo battery in child's rc car?

    I know this isn't e-bike related but hoping someone can give me some input on this: my child has a little rc stunt car, 3.7v 400mah battery that has to be taken out ea' time to recharge but there's space in battery box for larger. I remember when I first started out on here getting some warnings...

    Looking for small lock box that can be secured, like strong handle etc?

    I hadn't considered drilling the lock box; guess figured it'd be too strong; but from what I'm reading doesn't seem like it. Would I be able to use some Scotch-weld 3M DP 460 in the threads instead of welding?

    Looking for small lock box that can be secured, like strong handle etc?

    It doesn't do me much good if the lock box is stolen; if could find one with a strong handle could attach to u-lock or similar to something secure. I like the shackle type like for keys if there was one much larger to store documents and the like, any ideas? Thanks!

    Question about controllers that you can adjust the voltage?

    I built the pack using 9 Prismatic LiFePO4 3.2V/30Ah that I managed to fit into a Jandd Rack Pack 2. The pack's BMS controls each battery so can be different voltage "BMS for 3~16 LiFePO4 cells in series."

    Question about controllers that you can adjust the voltage?

    I can upgrade to 36v, have the other 3 cells. I asked specifically about 27v and he replied " Setting the voltage to 24v is enough to get the kit to work with a 27v battery." As I am new to brushless does this seem reliable?

    Question about controllers that you can adjust the voltage?

    I am looking at a front hub kit that the seller tells me I can adjust the voltage on it, is anyone familiar with this? I have been using a 27v x 30ah pack with a brush motor and while I have the other 3 cells to make it 36v the current setup works for me. Has anyone used a controller that the...

    Geared VS Direct Drive: Pros & Cons?

    I am looking at replacing my original direct drive front brush hub motor--which did require a larger front tire on the Trek Hybrid I had it on 38mm compared to rear 32mm, on a 700c rim. I have come across an inexpensive geared motor which on top of being inexpensive seems to take a narrower...

    The most comfortable saddle you've ever owned?

    Selle Royal seems like a very decent company. Recently I had an issue with one of their saddles; they were very pleasant to deal with, just asked to see pic of the problem and then sent me a new seat, shipped it from Italy. :thumb:

    Newbie looking for diy rear rack build ideas.

    There's also my pannier hooks. Right now I put a piece of eva foam between the platform and battery pack to raise it up level to the pannier hooks. Maybe do that with the new one too, gives it the resilience you mentioned. For extending the rack platform, I don't care about the weight, it could...

    Newbie looking for diy rear rack build ideas.

    The Tubus Cargo is the one I want. The larger platform of the Jandd Expedition would fit my battery pack better, each of those 30ah prismatic cells are 4"wide, 2.3"deep so if the 12"x4.5" Cargo platform could support that big a battery pack with some plywood etc over it then that'd be my #1...

    Newbie looking for diy rear rack build ideas.

    There's a significant price difference between the Jandd Expedition and the Blackburn, do you think one is better than the other? I'd get the Tubus cargo but my pack is going to measure around 7"Wx13"L.

    Newbie looking for diy rear rack build ideas.

    Got them quite awhile back, was going on memory; actually I ended up purchasing class 12.9 bolts and the nylon insert lock nuts say grade 8 but also state metric; am thinking seller just didn't convert to metric. They also go from using class 8 to grade 8 in the description. Looking again on the...

    Newbie looking for diy rear rack build ideas.

    That does seem like a good rack, and affordable as well. I've thought the lower mounting screws would be a weak point; DogmanDan told me about grade 8 bolts, much stronger; I also use 2 locking nuts facing outwards, might have to use a dremel to file down the bolt head on the rear cassette side...

    Have to re-adhere one magnet; should/how to remove adhesive the rest?

    Thanks for mentioning that about the plating on the magnets. Do you think the Loctite 331 would work better than 3m dp420?

    See a lot of inexpensive brushless hub motors nowadays (hallomotor etc) are these any good?

    Ebikeling says only 28-32c tire; isn't that a bit small?
