I been seeing Lime ebike abandoned all of over Calgary some of them in the middle of no where for example industrial area.
To sabotage such ebike would have been very easy with nobody around.
One abandoned in Foothills Industrial in the middle of sidwalk for 3 days.

Re: Cell -log help

I did not mean LVC and HVC buzzer.
I ment celllog had alarm output which was open collector output which can be configured as NO or NC.
Also Tenergy - does it displays all 6 cells voltage on one screen at once ??
I cannot find picture which displays it.

Re: 18% regeneration?

On my EPLUS on hilly terain raids CA shows 10% many times.
All depends what edrive do you use.
EPLUS has 9 regen levels - unmatched by any other bike edrive out there, DIY or factory.
DO NOT forget about brake pads wear.

Do you mean A123 20Ah pouches ? I have used them on 2 my ebikes. LiFePo chemistry cell has lower terminal voltage than NMC that I switched to 3.6V versus 4.2V But NMC dont last that long if charged to 4.2V comparing with LiFePo charged to 3.6V With A123 I used 12 in series, with NMC I use only 11 in...

Re: Stupid. Stupid. Killed a battery but no fire.

High Voltage cut off for individual cell is essential while charging
When any cell reaches whatever max voltage circuit must turn off charger.

Re: Juicing Up Pictures

I am seeing correct?
Do you use 3 laptop charges to charge 3 subpacks??
That is one complicated setup.
In last picture definitely are 3 charges stack up together.
I guess you cannot ride 30 kilometers on one charge.

Re: Battery pack casing options

I used 10mm ABS sheet to build the box with 3mm aluminium cover.
ABS is nice plastic to work with.
However all aluminium box is the best for keeping pack cool the best would be welded .
Waterproof box is the must of course.
Nedless to say all wires entering box from the bottom.

Re: Juicing Up Pictures

Marks
I see your point.
You want to see all the time that outlet is live.
I had several cases that power shut off during charging, but I have rather noisy fan in my charger .so that's my indicator.
