Not these days - this is from a couple of years ago

Some other suppliers still have issues tho although the firmware to fix most of them...

Just a thought

You could mount your magnetic mount by putting rivnuts



Or a no-drill water bottle mount

Agree, li-iron is a good choice for your application... just don't store fully charged, don't let them run all the way down and you will likely be go...

[AZguy]

Another point - in the life of this trike you are not likely to even come close to a few hundred cycles, let alone 2000 and that 2000 number is sort of...

Lithium iron phosphate (LiFePO4) sort of split the difference between lead-acid and the Li-ion more typically used in electric bikes - they are considerably...

[AZguy]

I suspect with four 16Ah lead-acid deep-cycle (make sure you get deep-cycle batteries) on that trike at 10mph I'd expect ~10mi, maybe more... but then...

Getting winblows drivers working has provided hours of entertainment... er frustration... for some!

[AZguy]

You aren't asking the right questions

Speed is limited by the motor and the battery voltage - according to the ad it says 28mph with 48V...

[AZguy]

Hahaha... my level 1 is 6%, 2 is 9%, 3 12% =]

I keep the speed limits in all at 100%... I really don't like the controller trying to speed...

[AZguy]

Ah rating has little do with how fast you go, that's more about the current (power to be precise) - Ah is the capacity so more about how far
...

[AZguy]

If you are looking for 4 to 5 hours, even at 8 to 10mph that's 32 to 50mi - a heck of a lot more than the 1 to 12mi trips in the original post!

It just holds one set of parameters and odds are that either one won't be perfect... frankly it's not a big deal to get a single set that covers everything...

[AZguy]

It looks pretty similar to the one I drew. The opamps in this one can pretty much be used interchangeably with the one I used in either circuit

[AZguy]

Well that pack is 48V so it has to be 13s and in the pictures I can count the bumps and it's arranges as 13s4p - 56cells

Industry standard...

[AZguy]

It's funny how just turning the pedals even without pushing is good for getting your aerobic capability up

When I first started riding I...

[AZguy]

Li-ion is going to take some nursing to keep have them sit for months on end

It's not a good idea to leave them for long periods fully charged...

[AZguy]

I seldom think much of a front wheel hub drive - one exception is for standard trikes (two wheels in the back) like what you are considering and as much...

[AZguy]

Those are actually chinese and frankly the difference between japanese and chinese is more than night and day IMO

Chinese sources are spotty...

[AZguy]

Good 48V/20Ah Li-ion for bicycle/tricycle use ≠ $150 - $250

More like 2.5-3x that - good quality batteries are expensive

48V/20Ah...

True that about how brains work differently =]

I can't stomach more than about fifteen seconds of a youtube video "manual" or any...
