PedalEase Amazon 1000W kit

[NeilP]

Anuone have experience with this kit and its LCD control panel

It is spec'd at 48 volt

A mate bought one,
Been wondering what max voltage it will likely safely handle
Not popped anything open, not wanting to tinker with it too much, while it is working

Battery gas gauge has 4 segments and with a 12 lipo pack charged to 50 volts it shows 3 bars, quickly droping to 2

So the 48 'label' voltage is a nominal pack voltage.

Should I push it to 14 s , so 58.8 volt, or play it safe and just go to 13s and 54 volts?

here is the display unit

I have a similar 48v kit, with the same lcd display. The battery gauge is rubbish at showing actual battery life remaining, better off just wiring up a simple voltmeter to your handlebars.

You should be fine going to 14s, but then you have to think about the low-voltage cutoff. A 40V cutoff means your 14s pack will be empty at 2.85V per cell, way too low imo. 13S=3.07v, 12S=3.33v. The LVC is more suited for 12s, and you probably wont gain more than a few mph by going to 13 or 14s.

BMS on the pack, so no worry about LVC.

The chap that bought it thinks the range with 10Ah is too low, but he has not even the pack down to cut off or done a full pack cycle yet, i told him i'd not rely on the gauge at all, but I cant convinve him it is useless.

I have put a CA-SA in line and told him to go ride the pack till cut off.

Max currrnt draw seems to be about 24 amps. Giving about 26Wh/mile

Your friend's Amazon kit looks like one of the newer Yescom black hub motor kits. markw and chasindayton wrote about theirs before. Here, markw finds 15S 62.25V won't run but 61.5V does. And here, chasindayton writes the LCD is a Suzhou City Kunteng Electronics KT-LCD1 and gives it's download link. The KT controller manual hasn't been found yet though.

I have no doubt that 14s x 4.2v will be fine.

I think most of the features in the display will be running on low voltage, only the battery bars will see pack voltage. I don't have the same display on the EBK stuff, but the displays I have go all the way to pingbattery 48v fine, which can be 60v fully charged. Not sure what the upper limit would be.

Thanks guys.
The owner shoudl be bringin the bike around later this evening..,. so we will try .

thanks for the links too. reading up now

all seems to be good, not let any magic smoke out the wires.

Same goes for the charger. (BMS battery 240 watt charger) turned it up from 50 to 58 volts and the current down to 3 from 4 ,

There was a nasty burn / flash mark on the back of the BMS, from before, but it seems to be working. couple of the mosfet pins seem to have been shorted with somethign ..bit of a flash but i have no recollection of it happening in the original build, but the battery both charges and discharges, so i left well alone.

The instruction slinked tio all show three display screens, where this version only has the two. so a feature reduce version by the looks of it..OEM firmware I guess. but no worries it works...hope it keeps working


If any oen in the UK thinks of buyign from the 'Pedal ease' company...i'd say DONT...they dont answer e-mails about technical, and when you phone the phone number from the website, it goes to what sound liek a domestic phone answering message..with the woman using her own name and no mention of the e-bike company

no reply to the message I left either.
