Cell Re-balance of Ryobi One+ 18V Li-ion Battery (130501002)
I charged the 4 lowest voltage cell pairs, one at a time, to the same level as the highest voltage cell (3.48V) using a spare 18V Ryobi battery. I connected one cell tab to one terminal of the spare Ryobi using thin bell wire (it''s like speaker wire). The polarity is critical (negative-to-negative, or positive-to-positive).
Electric battery
An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections [1] for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. [2] The terminal marked negative is the source of electrons. When a battery is connected to an external …

DeWalt 20V Max 3.0Ah Battery Pack Teardown & Analysis
The last new-to-me pack I pulled apart was a 26v BionX battery (which, I''d add, I rebuilt to nearly twice the stock capacity by filling all the space with cells). And I''ve got this cute little DeWalt 20V MAX battery pack (model DCB200, 3.0Ah) that''s just not behaving right. It would charge, but then only show one LED on the status bar.

How to supply a negative voltage from a simple battery or psu?
To use a battery to create a negative supply: Obtain a 9V transistor battery or a 4 or more cell AA alkaline battery pack or other source of 5V or more. (Or a mains "plugpack" power supply of 5V or more.) Connect the +ve terminal of the supply or battery to ground and. the -ve terminal will be at -V. eg a 9V battery will give -9V etc.
voltage
Electrons flow out one side (the negative one) and come back in from the other (the positive one). Current is not associated with electron accumulation, but with electron flow. The point of the battery is pushing electrons from the positive to the negative terminal: this pushing requires energy, that is chemically kept in the battery, used to push the electrons that then release it …
