Hi Everyone,
just received my neu CPx, double battery.
I noticed that:
Rear battery (A) will use before front battery (B) independently from the charge status;
If I have only B battery the scooter is "dead" (1 batteri in "A" slot works perfect).
Is this the correct behaviour?

In my case the CPX always uses the "less charged battery". I am not shure what happens if I only have the battery B. What I am shure is that always uses the less charged one. If the less charged one is the B it uses the B and keep the full charged A until B reaches 20%.

Battery lifecycle depends on some factors. Temperature has one of the most important influence. All tests are done in the ideal conditions of 25 degrees. By example below 0 completely forbidden to charge, and if you plan to ride (so discharge), keep the battery inside the house and bring it in the bike just before riding.
SoC and DoD of course contributes a lot on the number of cycles until the battery capacity will decrease to 80%.
In short: with charges from 0-100%, you will get around 300 cycles. With every 10% less than full, you double the "lifecycle". If you keep the battery in the range of 30-75%, you may reach easily 1-2000 cycles.
Of course you will loose your autonomy if you charge only to 75%. Best is to calculate in advance how much you charge based on your upcoming trip (short trips, charge less, long trips, fine to charge to 90% or 100, but not too often).
Have a look on your charger and voltage written on it. By example for a 60V rated battery, maximum voltage is 71.4V. In some countries chargers will come with 71.4V, while in others where warranty is 2 or 3 years), dealers will sale with a 69.7V charger which will bring the battery to a SoC of 90%, so already doubles the lifecycle and will not exchange too many batteries for free (under warranty).
Lithium batteries hate extremes... Extreme discharge, extreme cold, extreme overcharge, extreme warm.
That being said, the original charger does a good job not to overcharge the battery (even on 100%) because it only uses 70.5 and not 71.4 (which would be more fitting for 17S batteries such as ours).
So just don't let it on 10% in snow for a weak and you are fine 🙂
I only charge battery when hits 10% or less till full charge. almost two years here, and same consume use , for example home - work and vice versa. same % since the first rides...
