Battery pack calculator : Capacity, C-rating, ampere, charge and ...
A 0.5C or (C/2) charge loads a battery that is rated at, say, 1000 Ah at 500 A so it takes two hours to charge the battery at the rating capacity of 1000 Ah; A 2C charge loads a battery that is rated at, say, 1000 Ah at 2000 A, so it takes theoretically 30 minutes to charge the battery at the rating capacity of 1000 Ah;
Connecting batteries in parallel – BatteryGuy Knowledge Base
EXAMPLE: Two 6 Volt 4.5AH SLA batteries wired in Series would be a total output of 12 Volt 4.5ah. A battery has two terminals, one that gains electrons and one which gives electrons. Within the battery an electrochemical reaction occurs to produce electrons.

What is a Battery Management System (BMS)? – How it Works
Battery management system (BMS) is technology dedicated to the oversight of a battery pack, which is an assembly of battery cells, electrically organized in a row x column matrix configuration to enable delivery of targeted range of voltage and current for a duration of time against expected load scenarios.
Step-by-Step Battery Capacity Testing Procedure
Step-6: Record battery discharge voltage, current, & time at the start & the end of the test, as well as at regular intervals throughout the test. Step-7: End the capacity test when the battery reaches the predetermined end point voltage (1.8V), a cell (or) unit reverses, or a safety issue is identified.
