    iCharger 4010 Duo review

    Has anyone used the NiMh Mode on the iCharger 4010Duo ? I need to cycle a bunch of Rav4 95Ah cells/modules. I'm wondering if the 4010 in NiMh Mode will monitor each CELL for discharge cutoff? or is it set as a PACK cutoff voltage; ie, 10V for Pack vs 1V per-Cell? The Manual is not helpful in...

    BMSBattery/ECityPower Experience

    So sounds as though the GreenBikeKit Headways are genuine? Anyone discharge test them?

    BioPlanet ebike [apparently a fraud attempt - see page 5 on]

    So is this rotation-sensor-triggered motor ON/OFF, rather than torque-sensored proportional? And does it always take two rounds to trigger? How long is after-run? after pedals stop. Would like some functional detail please. Tell us about the controls too. Thanks

    Even Newer 4 to 24-cell Battery Management System (BMS)

    Hi Indub.... You could read this post from the beginning, and you'd end-up with quite an education in BMS's; you'd no longer need an "idiots guide"... R

    Even Newer 4 to 24-cell Battery Management System (BMS)

    Hi guys, I'd be up for some testing of the V4's. I'm still using a V2 I assembled. I haven't followed posts for a while, but I'm putting together an 18-cell Hipower LiFePo pack for which I need a BMS. I'd cycle it daily during my daylight shop hours, and not at night; our shop policy for any...

    BMSbattery / EcityPower 48v Battery Review

    I have a 48v 10AH slide-mount pack in the aluminum extrusion housing. Just have under 30 cycles on it. I use it on a Sun X3 Recumbent with GoldenMotor Magic Pie, and on a Mundo Cargo bike with Crystalite RoadRunner. On my second ride I heard some rattling, finally realizing it was the pack. We...

    A2B Metro - www.ultramotor.com - Video Page4

    NorthernMike On the Metro, the front & rear packs have same capacity, so I'm assuming same Sanyo cells, yes. On the Excel they will likely be different cell types, and perhaps not Sanyos; and forget the Power/Energy thing, sorry, a distraction. What I mean is the following; I expect front...

    A2B Metro - www.ultramotor.com - Video Page4

    Regarding a couple earlier posts...I think you guys have it covered, but wanted to mention that the Metro 2ndary battery cable uses just the two power wires. I'm an A2B dealer, and bought an extra cable to have around in case I wanted to try other types of packs on the Metros or Velocitis. I...

    Sky Energy Comment: wow, that shipping! via personal courier? SkyEnergy 60AH: let's see; $75 per cell + 21.45/cell shipping = $96.45/cell TS via Elite 60AH: wow, their prices went way up... $120/cell + shipping Jennifer, why did your prices climb from approx. $1.5/AH to $2/AH in such a short...

    Building my new BMS.

    Hi Patriot, Since you asked about Isopropyl Alcohol way-back, I thought I'd mention a couple things for the collective knowledge-base; Rubbing Alcohol usually has lanolin in it, I'm assuming to make it less harsh on skin(?), which is not great to have on PCB's. No, it's never listed on the label...

    Even Newer 4 to 24-cell Battery Management System (BMS)

    I just wanted to thank you guys for designing and offering this BMS to the EV world. I ordered one for my 20-cell TS 40AH pack today, and expect to order more in time(20-cell+). I expect you'll continue to be swamped with orders too as there are quite a few folks importing 3-4Kw bikes from China...
