    Ryobi battery Build - Am i ready to test?(update: success)

    There's a new p135 ryobi charger that looks a little better built. It might be a good candidate for conversion depending on how it's wired. Hopefully they'll mark down the older model and I can try to mod it.

    What do you think of these 18650's

    I've been playing with these for a few months without any major issues. They are 79$ at my home depot, but can drop even lower. there is a site called slickdeals(DOT)net and people post info about price drops and sorts. At one point they dropped to 25$ for 2 18V 4amp batteries and I jumped in...

    Ryobi battery Build - Am i ready to test?(update: success)

    Hey fellow ryoberry user! The 2 banks drawdown equally to within .01 volts of each other. There was one occasion where 1 single 18v self discharged, but I could not pinpoint the problem. I simply mounted the springs more solidly to provide better contact. The batteries didn't need to be...

    Taking a chance on Alibaba (K Power battery)

    I'm considering ordering one for a family member, but I have a quick question. When I check the link, it shows ( what I assume to be you) d*******n listed as a buyer of the samsung version. I don't want to make the same error and order the non-samsung version. Could you clarify what went wrong...

    Ryobi battery Build - Am i ready to test?(update: success)

    There is a youtube video of the P125 being disassembled. The spring contacts are directly soldered onto the main board. Which means I would need to scrape away traces and solder switch(s) to isolate the charger hardware. It sounds simple to cut 12 traces, but it depends on the layout of the...

    Ryobi battery Build - Am i ready to test?(update: success)

    There is a site called slickdeals dot net. You can sign up for alerts to ryobi batteries, specifically p122's. I think sometimes with coupons you can get them for 85 to 95$. If you wait, they may go on clearance down to $75, $50, or even $25. There was a ryobi promotion recently at Home Depot...

    Ryobi battery Build - Am i ready to test?(update: success)

    mclark999 - I think it should work fine since the pack can do 7.5C which allows 30A. If you can monitor your amps, you should be ok. I had one of the packs lose a connection, which essentially made my pack 54V 4Ah. It got warm and drained pretty quick. Looking forward to your build. dequinox -...

    Electric bike news source.

    Dogman dan 3000pts for awesomeness. The site has a quite a few links to NYC ebike issues which matter to me. One article even mentions my neighborhood specifically. Thanks for the heads up.

    Adopting Power Tool Batteries to Our Broader Uses

    http://endless-sphere.com/forums/viewtopic.php?f=14&t=68281&start=25 I made one of these and it works with the stock charger ( just pull them out and plug in ). The specs are in my post and I'll post a how-to guide when I've tested it further ( so far, so good ). The individual packs are are...

    powerwheels 18v conversion (works great)

    The wood holder is great so far, but it will fly out if you hit a really hard bump. One popped out at 20 mph when i hit a bump, but they are tough and barely had a scratch. My setup is 3 in series for 54V and then parallel for 8ah, so I haven't had any issues. If you want a pdf of the template...

    powerwheels 18v conversion (works great)

    BYqSXt8Z, your posts helped me build my first Ryobi Battery. Maybe I can give something back. The first is reusing the shrink wrap packaging to make a harness, the second one is a wood frame to hold/connect 6 batteries. I think for your kids power wheels, the shrink wrap would hold up fine...

    Ryobi battery Build - Am i ready to test?(update: success)

    After re-reading some old threads about ryobi p108's, I realize they are capable of 7.5c which allows 30A. My pack is 54V 8Ah, so it's capable of 60A. The fuse is 40A and I think this leaves a pretty good margin of safety. The range may not be great, but I'm not using this to do a daily commute...
