How long does it take to charge a lithium battery. The time it takes to charge a lithium battery depends on several factors, including the power output of the charger and the capacity of the battery. Generally, charging a
I have two lithium battery packs with separate BMS, Can I connect the packs in parallel, will the BMS get damaged or will something happen? 12v 10ah battery pack, I have three in total and each has it''s own bms and for now I want to connect two packs in parallel, I''m confused whether the bms will get damaged or what will happen? will it work?
The controller discharges the battery pack until the current SOC of most-depleted cell (SOC min) reaches to 30%. Similarly, the controller charges the battery pack until the SOC max reaches greater than 99% (~100%). Two flags CH and DC are used to determine whether balancing need to be performed in charging period or in discharging period.

My educated guess is that you are just making a 1S2P pack out of the individual packs. If they are at the same state of charge (voltage), the BMSs should not fight each other

During fast charging of Lithium-Ion batteries (LIB), cell overheating and overvoltage increase safety risks and lead to faster battery deterioration. Moreover, in conventional Battery Management Systems (BMS), the cell balancing, charging strategy and thermal regulation are treated separately at the expense of faster cell deterioration. Hence,

For example, in a ternary lithium 36V battery pack, a combination of 10 strings, if the voltage of one string of cells is 4.2V, and the voltage of other strings is about 3.0V. When the charger is charging the lithium battery pack, although the other strings are about 3.0V and the voltage is very low, the 4.2V string will instantly reach the overcharge protection value of the lithium battery

Lithium battery pack 48V20AH All lithium battery packs are composed of single lithium batteries in series or parallel; the way to increase the voltage is to connect lithium batteries in series, and the voltage is added;
Whenever possible, using a single string of lithium cells is usually the preferred configuration for a lithium ion battery pack as it is the lowest cost and simplest. However, sometimes it may be necessary to use multiple strings of cells. Here are a few reasons that parallel strings may be necessary:
Connecting multiple lithium batteries into a string of batteries allows us to build a battery bank with the potential to operate at an increased voltage, or with increased capacity and runtime, or both.
Therefore, the lithium battery must also be about 58v, so it must be 14 strings to 58.8v, 14 times 4.2, and the iron-lithium full charge is about 3.4v, it must be four strings of 12v, 48v must be 16 strings, and so on, 60v There must be 20 strings in parallel with the same model and the same capacity.
The whole set of batteries is 14 strings multiplied by 10 cells = 140 cells. Summary: Series and parallel have their own advantages for lithium iron phosphate batteries. Series and parallel lithium battery packs have different methods and achieve different goals.
Each Lithium ion battery (LFP) cell is 3.2 V and 105Ah in capacity --> 3 in parallel is 315Ah and -->30 in series will 96V for the Lithium ion pack. And Lead Acid bank is 12V and 100Ah. Is there any fundamental disadvantage to this solution? The devil is in the detail and you haven't provided enough detail about the batteries and load current.
Since lithium cells must be managed on a cell level, parallel lithium strings dramatically increase the complexity and cost of the battery management and introduce many additional points of failure and failure modes not found with a single string.
