    DIY Battery Upgrades for Goped ESRs

    Some of my connections are underneath the “BMS” base. The CellLogs, smoke alarm board and 9V battery holder (the black box) are attached to the top of the base with high strength Velcro. I tested the components individually and then went on to parallel the CellLogs alarm outputs...

    DIY Battery Upgrades for Goped ESRs

    As far as some form of BMS for the high discharge rate LiFePO4 Headway cells, I shamelessly picked up on the advice of others :D about using a smoke alarm along with my CellLogs and constructed a cheap, compact (fits under my ESR scooter deck), audible (loud), and effective (alarms for pack HV...

    I'm only speaking to my Go-Ped ESR Hoverboard experience, but right before building packs from headway 38120 cells I could not find a ready-made pack that met all the criteria I felt I needed. To be successful in the ESR I consider the following to be requirements: - pack no larger than...

    Extreme - please do keep the folks on this thread informed about your experience with the lipo packs. I'll admit I just couldn't muster up the courage to take that leap. I saw a lot of comments that made me think about the potential volatility of the chemistry and I didn't see a way to...

I attempted to make the pic titles...

    Scoot - My spacer has an actual height of 1.7" as I added a layer to the factory spacer to allow clearance for the 2s2p BB EVP1212 SLA configuration that I was running before converting to LiFePO4 cells. Add in the top deck layer at basically 0.5" and I have a total of 2.2" atop the battery...

    DIY Battery Upgrades for Goped ESRs

    Roughly yes...in real world usage...while enough capacity for my normal commute...I'm seriously considering gifting the 38120 packs to my wife and building 9s2p setup using 40160 cells to (1) get the most "go" out of what the stock controller will handle in terms of voltage, while (2) increasing...

    DIY Battery Upgrades for Goped ESRs

    I've had an ESR (Hoverboard variant) for a couple years and recently converted it to an 8s2p configuration using Headway 38120 cells. Personally, and with many thanks to a number of selfless contributors to an ESR scooter thread on another forum, I found the modification easy to do even for a...
