Adaptto Mini-E/Max-E Owner's Thread

Without OVS?

Even then its too slow.....

I reach 70kmh easy with 20s without OVS and 100 with OVS@7.

Also 18 inch, also QS 205 V3 5t.

On which paper the Samsung 30q is stated as a 3.5Ah cell???
Someone scammed you......it always was a 3Ah cell.

 

[DasDouble]

Maybe I have set up my max disscharge amper too low. Would you aggree to push 12A continous trough the Samsung 30Q´s? Or maybe even 15A?

 

[ziltoid81]

There must be something wrong, 8kw is way more than enough for 70kmh..........
Motor timing or something else is off the sweet spot.

Tested it 2 hours ago, 66kmh @75V without OVS.
With a full battery i reach 7x.

Your battery abuse depends on your expectations. .......
If you want this battery to last, dont push more than 5A per cell.
My 25r are getting max 6,xA (120A/19p) and thats a 25A cell.
Maybe others recommend more than 6A........everyone does this different.

I want to use my battery many years, so i reduce the cell stress to a reasonable minimum.

The 30q is designed to give 15amp but it will get warm when doing so for any considerable amount of time. For short burst/acceleration...no problem.

Once the cells get over 50 degrees C you will be shortening their life. I think 30q cells are designed to withstand upto 70 degrees

A 10amp continuous load will really heat things up.

 

[madin88]

With most 2kWh+ and big 205 Motor configurations, the motor usually will overheat before the battery temperature becomes noticeable higher.
Once the motor stays cool at such continuous abuse, the battery temperature should be watched.

Fact is the lower the currents, the better it is for the cycle life, and the cooler the battery, the better it is generally for the lifetime (the so called "calendar life").
However during usage it should have at least >20°C, and if you going to abuse it strong, a warmer battery would be better (less sag).

I personally would have no worries to adjust the controllers battery amps to 15A per cell (25R, 30Q and such), because I KNOW it will never be real continuous :wink:
15A on a 2,5Ah cell would mean it will be discharged in less than 10 minutes. Do that with a 10kW bike (if not riding 100kmh on the highway)

Ok so as we have made some things clear another quick question: What is the max. speed you folks get with your bikes? I have a peak of about 56km/h / 34mph with about 8kW peak (yes I know thats not my possible maximum with my Max-E but the circumstances dont allow higher speeds atm) with a 18" rear motor tire and the QS 205 V3 from Vector + ff from Merlin. How about you?

what battery voltage?
what motor kV?

Thanks madin . My battery voltage is 62 volts at the moment (80v to come).
Motor kV: 9.03kV

 

[ziltoid81]

I was expecting you have 20s already.

Your speed is ok with this voltage and motor......i guess we have the same 5t winding.

 

[DasDouble]

Thanks for that feedback. Now I know more. Another question:
I have made a trip of 25.1km (15.5 miles), the Max-E showed me following datas:
trip: 25.1km
908Wh
time: 40min
15.4Ah
rem: 6.5km
1900Wh
avg: 37.6kmph
36.1 wh/km
max: 71.7 kmph
10.1kW
reg:1.32Ah
0Wh
bat: 58.7 aVg
66 Ohm (???)



What do you guys think about this with a 16s 15p 30Q cells pack (and QS V3, 5t motor in a 18" moto-wheel)?

 

[ridethelightning]

36.1wh/km is nearly twice what it should be.

 

[DasDouble]

36.1wh/km is nearly twice what it should be.

Maybe I should add that this is with wide, open throttle 70% of that time..

 

[madin88]

36.1wh/km is nearly twice what it should be.

yes his consumption is much to high for an e-bike :lol:
with 66ohm your battery is in great condition

 

[brumbrum]

36.1wh/km is nearly twice what it should be.

Whaaa? Mines over 50, but that is stop and start off roading. Should i be concerned? Would swapping around phase wires alone make this change? Or would i require a resetup or auto detect at the same time?

 

[DasDouble]

I get that when Im riding to school (and when Im late as f*** :lol Its also slow down and full accelleration but with topspeed of about only 60 kmph. But when there are some people on the path, I have to slow down for some meters to ride under the radar.. (Also its maybe because of our weight difference )

Question: What is the biggest difference of your balanced cells? Mine is 0.011 volts (when fully charged up to 4.09v and 4.07v) When voltage goes down, mine is about ~0.37v or something like that.

Hey, I just wondered if anyone has been in contact with the guys at adaptto recently as I've emailed them a few times over the past 3 weeks regarding a repair but have yet to receive a reply.

Cheers

I have contacted them about a half a year ago via their webside. Normally they reply really fast. Maybe because of a orthodox holiday they are not in office.. I dont know.. Or you haven´t written your answer understandable why they don´t reply to you..

Yes, Oleg seems to be there on-and-off these days, I had to wait a few days for his reply.
I would recommend to send him a friendly reminder, with the dates of your previous messages so he doesn't have to search for them. Be sure your email contains all info necessary for him.

Thanks guys, I'll try again.

30-35wh/km is for our big bikes normal.

depends on riding and topoligy and weight.

on a normal ride i have 30wh/km, same ride from my girl (same bike, same battery, same controller,17" rear) she has 20wh/km (50kg less weight.)

on a 1/4mile run i have 80wh/km

going for a ride with dogs 20wh/km

weight is everything. when my girl rides my bike on 200amps she is near 2 seconds faster on a 1/8mile run. (not willing to go the full 1/4 on 120kph *lol)

 

[brumbrum]

I also have ovs on 1 just to perk up top speed a bit. I suspect that ovs is also an efficiency killer along with weight. I did get better efficency before updating the the RC9G4 firmware.

Another question: What is the biggest voltage difference of you batterys? Mine is 0.011v when fully charged (4.09v nd 4.07v). When disscharged, it is 3.33v and 3.23v. Is this good or bad? And is it necessary to balance it more when fully charged?
-Cheers

Sounds good to me. Most people say to keep cells within 0.050 of each other. As long as you have your adaptto bms set to cutoff power when the first cell gets to say 3.0v under load with 18650 cells then all ok. Set the minimum and critical levels to this in bms cell settings. With my lipo cells I set them to 3.3 or 3.4v due to voltage sag under load. When at rest the cells will show much higher than this.

Adaptto BMS is about +- 5-10mV accurate.
measure it with a calibrated voltmeter und you probabaly will see differences lower as 2mV.
below 3,3V or 10% SOC the drift will become more and more (at least i notice this on all of my batteries).

Ok good to hear. I already thought my cells could be damaged from some powerchargings some time ago that the differce becomes bigger with time. Thanks a lot

absolutley...and if you have calibrated voltmeter, you can setup your bms to the "real voltage" for each cell(p)

Oh man I love this forum.. It teaches you soooo much more then you would learn from somewhere else like in school or something like that.. Just love it
