    Buying used Leaf in USA - general advice?

    The family is taking a trip this August to see the eclipse in Oregon, then to the dunes and redwoods before heading back up to Canada. I'm now convinced this is the time to bring back an off lease Nissan Leaf with us. From what I can tell - prices on used Leafs in the USA are 4-5K lower than...

    14s7p Panasonic PF build - current sharing advice

    I'm about to start on my third battery build. First was a recycled toolpack cells from Makita packs long ago that I put together for my lawnmower. I learned there that even if it was OK to solder cells, I'm nowhere near good enough at soldering to make it OK for me. I also learned I don't...

    10s3p best 5x6 layout for current sharing?

    Hi, I'm getting set to build up my first battery with the JP spot welder. This one will be a 10s3p mini pack using panasonic 2.9Ah PF cells, and I'm planning on a 5x6 rectangular layout, partly to make a nice compact shape that can fit in a seat bag, partly because I got the batteries (from...

    Cordless lawnmower SLA > lithium upgrade advice

    Just moved to a new house, and now I have a 1/3 acre property with more grass than I can handle by dragging the 100' extension cord around. I do however have 116 tested makita cells from DrBass in the garage from my earlier plan on building myself an ebike battery that got long delayed...

    Hyperion 1420i voltage readings -- something I'm missing?

    I purchased the charger about 5 months ago for my very slow (I have small children) toolpack 14s battery build. I had noticed previously that the cells I was testing were coming off hte charger at a little over 4.1 in lipo mode, but didn't think too much of it. I'm getting back on the project...

    First battery build and first RC charger questions

    Hi all. Got my toolpack batteries from doc all pulled apart, and my hyperion 1420i charger arrived yesterday. My holiday project will be to turn this pile of bits into a 14s/as many as I can-P pack. First - for the charger, I'm planning on using a deep cycle 12v RV battery for starters...

    Hobbyking 6s Lipo recommendations circa Sept 2013

    I've decided to risk the apocalypse and use RC Lipo for my commuter bike, my Ping 48/15 pack having finally given up the ghost. The deciding factor was a colleague at work offering me a deal on his Turingy balance charger, which makes the economics too hard to pass up compared to pre-built...

    Ping output voltage issue - bad BMS again?

    All, I've got a 48v/15Ah ping v2.5 - last year, the BMS got replaced as one of the charge LED's was staying lit, and a single cell group got drained below the remainder. The weak group remained above 2.8V, so the damage was likely minimal. The BMS was replaced, and other than that weak group...

    Ping v2.5 BMS dead?

    Today my power cut out on my ride. It was normal power levels until - nothing. CA screen faded in and out, and was showing voltage in the 20's (on a 48v battery) during this time. Checking the BMS - one LED is staying constantly lit - on the end of the group. I can't tell for sure without a...

    Ping 2A charger - bad connections?

    Hi all, I have an ebikes.ca 9C kit that recently went through a round of troubleshooting/replacements. After getting the kit all sorted out, replacing the controller and motor (all under warranty, and with excellent support from ebikes.ca) I seem to be unable to charge the ping (48v/15ah)...

    Accidental regen on non-compatible controller?

    Hi all, I am running a ebikes 9C front kit with crystallyte 20A pedal first controller (no regen) and a ping 48v/15ah battery. Today on the regular ride, I'm heading down the steepest section of my ride. Very shortly after releasing throttle, I notice a strong shuddering. It felt a little...

    New 48v ping arrived - a few questions

    Hi all, My 48v/15ah ping arrived today - or at least I think so because there are no markings to indicate anything (somewhat expected). A few questions: 1. The charger is a 60v unit (as labeled on the unit and a little hand-drawn sticker on the bubble wrap). I assume this is expected as the...

    battery upgrade: ping 3.0? options?

    Hi all, I've been running 10 months now with a 9C front kit from eBikes.ca. Overall very pleased, but my 8Ah niCad pack is no longer giving me nearly 8Ah. I had a blown controller replaced under warrantee, so perhaps it did something to the pack on it's way to the grave, or perhaps I just was...

    Low voltage cutoff and sag

    Hi all, I am running a 9C kit from eBikes.ca with a 36v/8aH NiCad. The site states a recommended 1v per cell as the low voltage cutoff to prevent cell damage, that would be 30v. With the cycle analyst showing around 6aH discharge, the pack runs around 32-33v with no load. Running level, sags...
