Connect two fuses, one at the positive and one at the negative battery terminals. Also, during my research, I came across a post that advised to connect a fuse at the positive terminal since it would protect both circuit and the battery, but if the fuse is connected to the negative battery terminal, then it only protects the battery. Is this true?
To re-start the battery simply connect to a Dakota Lithium LiFePO4 charger to the battery. The charger will tell the BMS inside the battery to turn on the battery and re-charge. ... an electric cooler that a power draw of 1 amp can be powered for 100 hours by a Dakota Lithium or LiFePO4 battery or 40-50 hours by an AGM or lead acid battery ...
Examples include "Best 3.7 V recharg lithium battery", "Rechargable lamp (red)" (status led), "Micro USB plug 5V power/charging", and "(lithium battery or power need >1.5A )".

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 …
One type of lithium-ion battery is the lithium iron phosphate (LiFePO4) battery. LiFePO4 batteries have a number of advantages over other types of lithium-ion batteries. For one, they''re much more stable and less likely to overheat or catch fire.
(And if you remove the battery when the computer is OFF same thing happens when you try to start it up.)

Nothing ''failed''. With the battery connected in reverse the rectifier in the alternator would have been forward biased, causing a very high current to flow because it is connected directly to the battery. Luckily rectifier diodes can handle very high peak currents, so provided the fuse opened quickly they should have been protected.

This ohm law is wrong application for a battery under charged, the battery is not a resistance device, but a capacitance device instead, so if the charger supplies 2 Amp the phone battery will accept 2 Amp charging current as this ohm law: P = IxV, V = 5V constance so current I will change if the charger power is higher than the device require.
For example, a 100-amp-hour lead-acid battery weighs around 70 pounds, while the lithium version weighs just over 30 and has twice the usable capacity, making it 1/4 the weight per energy! For those building a large battery bank to camp off the grid, this can save several thousand pounds of weight.

In reality, using a 3.7V battery to power a 5V device, a 3.7V to 5V boost converter required. You can think of it as a pump. As a working water pump requires energy, the 3.7V to 5V boost converter will consume battery power as well. So, not all the battery energy is used by the device. The boost converter also consumes battery energy.
They offer a native voltage of 12.8 volts, which means they can provide your telescope a full 12-volt power for 95% of the battery''s capacity. Despite handling higher current loads (3 amp for the PowerTank Lithium and 10 amp for the PowerTank Lithium Pro), they have the safest thermal runaway temperature of all chemistries at 270°C.
