FAQS about NiMH battery cabinet always cannot be charged
Can You charge NiMH batteries off one Charger?
I wouldnt attempt to charge NiMH batteries off one charger dude, mainly due to the charger not being capable of charging NiMH in parallel or series very well...they struggle to cope with charging NiMH batteries with varying levels of discharge / capacity...which usually leads to over/undercharging in some of the batteries cells
How to charge NiMH nickel metal hydride batteries?
Unfortunately charging NiMH nickel metal hydride batteries is not as easy to achieve compared to other types of cell or battery. The NiMH cells, like NiCds require charging using a constant current.

Can a NiMH battery be overcharged?
3. Don't overcharge, don't under (trickle) charge Nimh batteries should never be overcharged, the maximum capacity for any NiMH battery is 120% (which is what your NiMH charger SHOULD charge your NiMH batteries to before auto shut off, @Rudd looking at you)
Can a NiMH battery be slow charged?
Slow charging NiMH batteries: NiMH battery slow charging is not to be recommended. Using charge rates of between 0.1 and 0.25C do not provide the indicators needed to detect the end of charge.

What is a lithium ion battery pack?
The lithium-ion battery pack is composed of multiple single lithium-ion batteries connected in series. Due to the differences in the cells, when the terminal voltage rises inconsistently when charging in series, some cells will be overcharged and some cells will be undercharged.
What happens if a battery pack is out of balance?
A battery pack is out of balance when any property or state of those cells differs. Imbalanced cells lock away otherwise usable energy and increase battery degradation. Batteries that are out of balance cannot be fully charged or fully discharged, and the imbalance causes cells to wear and degrade at accelerated rates.
How to balance a battery pack correctly?
needs two key things to balance a battery pack correctly: balancing circuitry and balancing algorithms. While a few methods exist to implement balancing circuitry, they all rely on balancing algorithms to know which cells to balance and when. So far, we have been assuming that the BMS knows the SoC and the amount of energy in each series cell.
Why is the voltage of a lithium ion battery inconsistent?
When the lithium-ion battery pack is produced and stored for a long time, due to the difference in static power consumption of each circuit of the protection board and the different self-discharge rate of each battery cell, the voltage of each string of batteries in the entire battery pack is inconsistent.
