    Yamaha battery compatibility - PASB6 with 2016 PW series? (X0R40)

    Hi all, Does anyone know if Yamaha's current battery offerings are compatible - at a communications level - with older model PW series motors? I have a 2016 X0R40 PW and would like to buy a new spare battery dealer-direct for one of the Moro bikes (PW-X3). Here in Canada it isn't possible to...

    Hatching a glass-bottomed plan

    So, you folks might remember my S.A.F.T. acquisition of a few months' past: Exhibit A. I was planning on using these to power the moped conversion, but their 80lb weight scared me off. I had the opportunity to drive an aluminum fishing boat (14 feet long) with a Minn Kota 12v trolling...

    What would you use to charge 20x 27Ah SAFT NiCads?

    So I'm going to have my Saft NiCads next week and need to be able to charge them. I was thinking the Astroflight 112D would be up to the task, but AF's website seems to say that it's charging capability tops out at 9,000mAh. My batteries are 27Ah... That 9,000mAh is just the limit of what...

    $ / Wh?

    In looking to price some NiCads for my moped build, I've realized there's no easily searchable reference for the going rate of $/Wh. Or, perhaps there is, and I'm just too tired. It's been one of those weeks. Anyway, folks, what do batteries actually cost? Can you let me know what you...

    Fair price for 20pcs SAFT 27AH 1.45V refillable NiCads?

    Hey folks, From my other thread, an update - 20pcs are available to me, and I'd like to offer a fair price for these units. Information to consider: - Age is unknown, MSDS supplied with the cells is dated 1990. - Cells have never been used or opened, electrolyte has sat undisturbed. - Peugeot...

    Edit: added pic. Hi folks. My boss has a small stock of SAFT NiCads he's going to sell me, I need to come up with a reasonable price to offer him ... they're 27Ah, refillable NiCads .... that have apparently been sitting for 10+ years. He's not sure if he has 12 or up to 20 of them - he's...

    Idea - 1 cell to 1 pole. (?) Brushless motor development..

    Hey guys, here's something that's been on my mind. A typical setup uses a bunch of cells in series to drive a multi-pole motor - does this not create a "bottleneck" effect of sorts? Why not, instead of running let's say 480V (for argument's sake) to a 3 phase motor, why not run 120, 4V...

    Using two drive chains to one hub - one on each side?

    Guys, I see a lot of you working on how to combine pedal and motor power and see it finally coming together with a few questions about Matt's drive in the last few days in other posts. Here's my thinking - not new at all, but incomplete - I hope it contributes something. If you use use a chain...

    How to find peak power + best final drive for HXT 80-100-B?

    Hey guys. So, having been 2.5kms or so on my HXT 80-100-B moped conversion geared probably way too high, I'm curious as to how I should calculate a proper gear. Top end I will estimate at 50-55kph running 48V of marginal SLA. From math I don't grasp, at 48V x 130rpm/V, I should be doing...

    Connector options for brushless R/C motors

    Guys, I need to figure out what connectors to use between my HXT 80-100-B and Castle 110 HV. Both leads appear to be approximately 10 AWG. The motor connections appear to be extensions of the windings, and a Kontronik product on the Tower Hobbies website specified that similarly constructed...

    Usable range predictions for moped conversion?

    Hi folks. If you've been following my moped conversion at all, sorry it's taking so long! I've recently become worried about my batteries though. I was planning to use a bunch of 12V 7AH sla I happen to have on hand - 4 in series, specifically - to run my HXT 80-100-B. I'm concerned I won't...

    Servo driver w/ a 5k pot?
