    use 52v battery for camping

    Hi John, I don't have much experience in DC conversion. I understand it's lossy (not efficient) to change voltage but what is fragile about it? I am trying to save money by using a large battery I already have to set up a system. Do you think it would be "less lossy" to setup an inverter off it...

    use 52v battery for camping

    Hi John, we have another system on the boat for charging other stuff so the bike battery will be used exclusively for the 40L fridge and loading I have mentioned was from someone using the fridge at 12v at 32 degrees which is midsummer temps for us. Sent from my SM-G950F using Tapatalk

    Kids ebike

    Thanks guys Great info, I have had a good look at the bmsbatt kit which would fit nicely on the 16in rim. Just wondering what you think the issue would be with putting 2x 18v in series for 36v? Already having the batteries and them being smaller (4 or 5ah) makes them much easier to fit the...

    thanks for the link Motomech is it possible to modify the throttle with resistors to adjust the span until she gets used to it? and also any tips on estimating the spoke length? Or is it easier to buy long and cut and thread it myself?

    Hi guys I am endeavouring to convert my daughter's byk e-350 with a front hub motor and either 18/36v (one or two drill batts) How would this kit stack up? I need 100mm dropout on the front and my rim is a weird 355mm. I think i This may be 18". Not sure what size rim to go with. Lots of 12"...

    Battery BMS or charger phone alert

    Hi guys I've been thinking lately, wouldn't it be nice if my battery bms or charger could alert me when my battery was finished charging. I'm assuming that there would need to be a sim card pcb added to the bms or charger to allow this to happen. Has anyone attempted something like this...

    Converting a Bakfiets cargo bike

    Thanks MalcomG Very nice install. There are a few steps to go before we install the electric motor and I will use this post for reference. The bike's gear selector was very sticky and the handlebars are very narrow but we dropped it off for our mates and I will send them the link. They are...

    Bafang Max Drive - configuring

    So far I suspect the display as no blown mosfets on the controller and getting throttle 0-5v feedback from torque sense cable (red 5v, black 0v, grey signal 0-5v) BUT getting good power return on the right pins and no shorts (used Luna BBSHD wiring diagram) from the display so cabling from...

    Norco scene for donor bike, motor options?

    Thanks, if I get a shark battery from Em3ev it won't fit on the bracket though will it? As it uses a full length bracket. Any recommendations for trusted sellers for this style battery in 36-52v 17-19ah range? Sent from my SM-G950F using Tapatalk

    Norco scene for donor bike, motor options?

    Norco scene for donor bike, motor options?

    Thanks for the feedback guys, I am thinking I would like to keep this bike fairly stealth and go with a rear hub motor. Options are either the ezee or bafang 310 or similar performance hub motor. I really like how the rtr kits from grin slide the controller under the battery and one connector...

    Converting a Bakfiets cargo bike

    Positiv, bike would be about 30kgs I reckon, give or take the amount of crap in it. We have been testing on some decent hills this weekend and I have been surprised it hasn't cut out. That said we use the pedals going up hill to help with torque and carry momentum into it. Malcomg, I'm keen to...

    Converting a Bakfiets cargo bike

    Hi Malcolm, have you made any progress? I'm keen to see how you go with a dd hub as we have a 350w geared hub motor on our bakfiet, front wheel. Good performance although our area is fairly flat. Small amount of motor noise but nothing outrageous. Throttle only control, keeps the chain...

    I did get a 72v lipo battery off jonesc but drained it when I left it connected to the bms [emoji24][emoji24][emoji24] but, yes the 52v li-ion battery came from China, through Em3ev. Can ship if they are handled right. Sent from my SM-G950F using Tapatalk
