    Many model/fighting lightsaber builders like UltraSabers and Saberforge as well as others use only the Panasonic and Trustfire batteries with Panasonic apparently being the best of them all.

    I don't know about Ultrafire vs Trustfire but I can confirm that Panasonic 18650 ones are very reliable - I've been using them for years for things like aforementioned lightsabers and flashlights. (The NCR18650B 3400MAh 3.7v ones.)

    You can get 2 for $14 atm. I was actually quite surprised to see that kind of capacity at that voltage considering the size of the things.
    I agree the panasonics are very reliable but at twice the price you could build the cheaper pack again which is far easier the second time with the case having been opened already in a few years if you needed to but more likely they will last until you upgrade. If money wasnt a problem sure but then if money isnt a problem why not just buy an oem pack for $95. You could even use some 14500's in place of the optical bay to extend the mAh if money werent an issue.

    I have had a number of requests to build upgraded and rebuild worn out packs for people so let me post this here. I work 60-80 hours a week and really dont have the time but if someone absolutely needs it i will let my son build a pack for $50 that includes the linked batteries and ill of course supervise him and test it. Or you can send whatever cells you want plus $20 for his labor. He has already build 3 packs for laptops and 5 for ebikes so he knows what he is doing. You will need to message me to set it up and send the battery or the entire laptop if you dont feel confortable removing the battery here to Los Angeles and include a prepaid return label or drop it off if you live locally. You can also find a replacement battery for as low as $95-99 dollars online and have a shop swap it or swap it yourself. Feel free to message me if you have any questions.

    The case would have to be modified and an easier connector wired inline but yes it could be removable.
    You could make a second battery pack sure and wire it in or place a jack and use a barrel connector on the laptop. It would add weight though. You could even 3d print a new top cover or a skin over the top cover to hold quite a few cells. You would only be limited by the weight you would want to carry and the cost of course. You could even make a pack with removable cells and use chargers to charge and swap those cells. The question becomes how much battery life do you need and how much are you willing to pay/carry around for it.

    I would only need the battery itself if your goal was modifying the case or installing a 3d printed bottom cover yourself. The pack has very little room so if you wanted an easily removable individual cell option i would suggest a 3d printed battery case aswell to give extra room for the springs. You might consider just an add on bank of batteries and wire it in to the current battery with a removeable plug that way you could use the same charge circuit and it would just read as an increased mah and charge for longer. Thats easier than carrying a seperate charger or a handful of seperate batteries. There are too many options to list it really comes down to what you need from it. How much extra charge do you need how much weight can you add and how comfortable are you with modding.

    You could do a very slim battery pack with a couple 10440 cells to give you just a few minutes of emergency power and not have any issues with laptop not detecting a battery. I dont think it would be worth it just to save a few ounces.

    I suppose but figure out what size mouse pad your talking about and the acceptable thickness because using 18650 cells are thicker then others and would be the best bet for maximum mah. For 18650 cells your looking at a 1 inch thick mousepad plus whatever material your puytting on it and while i could 3d design it to slope downwards so that it sits flush with a desk that thickness might bother you. It could probably also be build on to or into a cooling pad that would depend on the pad. You still need to wire in a barrel connector somewhere if you are charging it with the standard power brick.

    does battery pack have a circuit in it?
    what about MCU ( micro controller unit) 's program that contains battery's specificity?

    Yes it does have its own charging circuit that regulates and balance charges the cells. It uses delta peak voltage to determine charged level so the capacity of the cells doesnt matter for the circuit.

    Talking Wait, So I didn't brick my pack by removing all the cells

    I got to reading a lot online about the chips in newer laptop batteries having a protection circuit, and if the board receives 0 voltage it gets bricked. Is this not the case with the G751 pack? I really hope so. Because I'd like to go ahead with replacing the cells instead of throwing the pack away and ordering another battery.

    What's the best way to remove the plastic shell that's around the batteries?
