This is, in some ways, related to my last post topic too... I have been looking at various types of battery options to power projects. At first I was thinking about Sealed Lead Acid Cells. (This are not But... I have some BP-511 Batteries. They are Lithium Ion Rechargeable. They are for My Canon SLR and I have always liked them. During My Search for Batteries that I like, I recently found the BP-535. It is Basically a BP-511, but about 4 times the Capacity, in a larger case, I have been trying to find "Technical Details" on it. So far I have found Specifically charging sequences, voltages, and what the 4 metal tabs are. I think the "+" and "-" are covered, but that still leaves the 2 tabs Also... Any idea where I could get Battery Holders for these if I went this route? My last, current option, is just to get a bunch of rechargeable Lithium (I have been tending to like that idea more-and-more the last week or so...) |

B and D are probably two ends of a thermistor. For measuring temp while charging. BM |

You have to be very careful when charging Lithium Ion Rechargeable batteries. Temperature can be critical. I don't know if I would trust a home made charger. Look at the trouble Apple had with their batteries or Boeing for that matter. Different batteries but lousy engineering caused fires in both cases. Ralph |

Hello Ralph, Thanks for the Warning... I have paid great attention to numerous failures regarding Lithium-Ion usage. I think the "worst of all" was Tesla... Come-on Elon? (Probably he was leaving that Yes, I am very aware that Litium-Ion batteries can burn or worse turn into "little More-and-more of them are coming with Integrated Control Circuitry to prevent both I have more projects that are using battery power now and while I have been, mostly happily, using Energizer Rechargables but I have been reviewing options. Since I ran into the BP-535 I am starting to like that more-and-more for my uses. That was why I was wondering about additional Technical Details regarding that particular battery. (Well "Battery Pack"...) My "old/original" charger for my BP-511, which the BP-535 can use too, did use "all 4" The "new chargers" ONLY use the "+" and the "-" contacts? I got to thinking that maybe that design has been updated to include Integrated Control Still looking for Technical Details, as well as battery holders for these... |

"Still looking for Technical Details, as well as battery holders for these..." As far as battery holders go I have a concept of printing a "battery holder" that will fit/integrate a different companies charger. I have a number of 18v. power tools and I have some B&D 20v. lawn tools. I'd love to be able to use my 20v. batteries on my 18v. Makita power tools. Plus I'd like to make a two battery holder, especially for my lawn tools. I have a 3D printer coming so I could print out the holders (as long as I can draw them in my 3D modeling GeoMagic). Knowing what each pin is would really help. Of course I don't know when I'll get around to doing this right now it is just a concept. If you know 3D cad and can make a drawing of your battery holder I'll be able to print out one for you. Ralph |

Hello Ralph, Thanks, that does sound pretty cool. I have been watching the posts you have been making regarding your 3-D Printer. Hopefully you will get it soon, and it work well! I have often thought about 3-D Printers and uses. Custom Cases, Custom Strange Parts, I have been playing around with the multiple BP-511 Batteries that I have. (They have I can make a pretty decent batter holder using 4 small bolts, spacers, and washers. I think I may end up going that way. (More flexible too.) Who knows though... |

Did you know that sound travels via pressure waves in the air, and you can make these with a piezoelectric buzzer? Learn more...
