Questions regarding percentage charged after connecting EP100.

[andywuzc]

Hi all

I recently bought BP100 and a week later added an expansion pack Ep100.
On the initial first charge for my BP100, the charging to full 100% display was within 10 minutes on hardwire way ( it was pretty quick until input flow showed 0A with occasional dischargeing, charging and stopped ).
Is it normal to reach 100% within such short of time?

My second issue is while Bp100 displays 100% charged, what happens when EP100 get plugged into ext port? I thought by doubling the capacity, I would see some drop on the displayed total combined percentage.
In my case, It remained at 100% charged with continuous charging at 100% on 12V-14V at 7.5-8A.
After a day of charging, I think both batteries are fully charged because amperage value decreased gradually lower to less than 1A at the end.

I feel that battery app is giving me wrong values. Especially the percentage is way off as well as remaining time, time to fully charged never got a value on it.

I am thinking to unplug the hardwire power to let the batteries drain to nearly empty to run a full cycle full-empty- full to see if this fix the problems.

I've tested a couple different dash cam battery packs.
Usually they are delivered / shipped in a 50% charge state.
However, sometimes they are 0% or 75%.
I think I remember the Viofo's were delivered at 75%.

As far as APP Battery Percentage accuracy I think you find it will become more accurate after 1, or 2 full charge / discharge cycles.

Upon the initial connection between the EP100 and BP100 batteries, the battery levels will not synchronize; the EP100 cannot transmit its current charge level to the BP100, so the app will initially show the BP100's charge level. Synchronization will only occur after the batteries have been connected and both have reached either 100% or 0% charge.
