    Salvaged EV cells index: Leaf, Volt, Tesla, Zero, etc

    Great thread. The Prius NiMH does have those breathing nipples on the top. I bought a full Prius battery and used it charged at 280 volts or thereabouts. This was in an open boat. Each nipple got a scrap of scotchbrite in it, and I still have of those modules working from 2013. Leaf...

    looking for ideal base for electric car conversion

    I'd forgotten: The Benz 250e is closely allied with Tesla, and thus probably carries a battery bank of 18650-type batteries. These don't inspire confidence in me, there's just too many of them, too many connections, too mind boggling....

    looking for ideal base for electric car conversion

    I did the search here, found no entries on MB 250e. It's the Benz all-electric hatchback. Used off-lease for less than $25k. AND it desperately needs a conversion: equipped only with a slow charger, single phase. Surely some wizard here could come up with a rapid-charge conversion that would...

    Improving a trolling motor

    Do trolling motors have ball bearing shafts? That's a basic question. I know the last trolling motor I took apart had only a single ball bearing on the front end. This absorbed the thrust, and it served as the bearing, sitting in a round recess of the commutator shaft. Pretty basic...

    Catamaran run-about, outboard conversion

    Torqeedo outboards are pricey, but effective. The first three or four finishers in the Wye Island Electric boat marathon (25 miles!) for the past two years have been with Torqeedos. Here's the opener; check the Dec edition PropTalk for standings. http://www.proptalk.com/electric-boat-2015/ I...

    Catamaran run-about, outboard conversion

    Excellent, inspirational! You put in as much time posting, probably, as you did building! Wonderful attention to detail on both counts. Thank you!!!

    Battery a Fire Hazard only when Charging and Discharging?

    Makita-lookalikes BEWARE: one went into my bonafide Makita charger, next thing I knew there was popping then banging and finally fire shooting out the battery on the charger, and 18650 shells propelled out of the battery. Yes the fire extinguisher was handy. Lots of smoke, fire. These were...

    Dynomometer from Harbor Freight?

    I have six pmac motors with various inputs and numbers on the labels. In our real world, I've no idea what powers they might be able to produce. And no idea what fine tuning might produce any changes. So this Harbor Freight generator seemed like a worthwhile try. And once coupled up with a...

    Dynomometer from Harbor Freight?

    Harbor Freight offers this 10000peak watts brushless generator. http://www.harborfreight.com/10000-watts-max-7200-watts-rated-belt-driven-generator-head-45416.html Is this something that could practically give hp output readings on some of the larger motors? What would you use as a load? The...

    Adopting Power Tool Batteries to Our Broader Uses

    Re the Makita batteries. There's a thread dealing with "docks" that are pretty complete units to help mount/tap the LXT battery. AND, Makita has a more basic one, they label it a "terminal" http://www.ereplacementparts.com/terminal-p-719473.html?q=Makita%20%20643852-2

    Pms 126 motor and acd 4805 controller

    Wires 1 and 2 and 3 go to U and V and W respectively. You have a Danaher controller , the ACD4805. Understand that it is going to output about 2kW to the motor. Zapi controllers have taken over; evs-inmotion.com deals with new controllers. Go to the Heinzmann website and dig in their...

    Stainless vs aluminum surrounding motor can

    Try dropping a magnet down an aluminum tube. WEIRED slowdown. So the suggestion to run the motor in and out of the chamber seems a good one: note the readings, performances, etc.

    Electric boat marathon (race)

    This seems the right place to alert electric watercrafters of a 25 mile electric boat race on the Chesapeake this Fall. The Wye river on the Eastern Shore is the racecourse. Mark your calendars for October 2. Rules of the race: http://www.electricboats.org/2010-Wye-Island.html How it went...

    Recharging Lithium Titanate cells: Toshiba SCiB BMS: Help?

    I'm pretty sure I had the battery fully assembled and the systems allowed me to charge through the gold female terminals. BUT!!! then when I asked for emf from the discharge terminals, there was nothing there. All KINDS of failsafes, for one reason or another. Isolating the cells from the...

    Recharging Lithium Titanate cells: Toshiba SCiB BMS: Help?

    I just don't have the technical knowhow. The battery comes with two separate charging points, as well as the third discharge terminals. No way would the included charger cooperate even after I'd nursed 10 cells up to 2.4 volts. Yes, a BMS would be great. If you're able to make it work, 3...

    Adopting Power Tool Batteries to Our Broader Uses

    Home Despot today has 4Ah 18volt replacements 2 for $100. I can see the time when your bike carrier has three or four plug-in receptacles for a Makita or DeWalt or whomever lithium batteries. You wheel out your electric bike, grab a battery from your string trimmer, another from the recip saw...

    Recharging Lithium Titanate cells: Toshiba SCiB BMS: Help?

    Been there, done that. As a shadetree wrench, I couldn't handle all the circuitry in the battery itself. I sliced out all the diodes and gizmos and reassembled the battery with leads directly from the ten cells to the terminals that match the controller power in buttons. I drilled small holes...

    Measuring remaining AH for Pulse electric trolling motor

    Getting a read on voltages is important also. Record the voltage at the start; for longevity of the battery, folks say don't charge above 4.05 or somesuch. Ditto for longevity, don't drain below 3.5 volts or thereabouts. The voltage limits you choose will depend on your wallet, the demands of...
