Q:12V battery pack without protection board safe?
Can not. Resulting in lithium battery over discharge, affecting life.
Q:One of the battery pack to die, and a piece of it?
One of the batteries in parallel, this battery output capacity is twice as large, but other batteries can not output the same current, so no use.
Q:Why some ups battery pack to take the middle of the tap?
Popular point that is high-frequency UPS he has a symmetrical point, plus or minus equal. It is necessary to pull a middle line from the middle of the battery.
Q:Ups how to pick up the battery pack?
First of all you have to look at the power of UPS, some high-power machine power supply voltage is 24V or 36V, UPS battery power supply voltage is 12V, there are positive and negative, this you have to distinguish clearly.
Q:Is the battery pack good for 18650 or the polymer?
In the security point of view, as 18650 battery reliable, such as electric vehicle battery pack, usually with 18650 battery composition.

Q:Will the battery 18650 battery capacity AH is how to count?
And the data is exactly equal to the product of the battery tag. To six core, for example, 48.84Wh = 11.1V × 4400mAh.
Q:Electric car battery pack capacity 156ah on behalf of several electricity?
A few times is the power, the unit is: kWh KWh, battery capacity is: AH
Q:Making a battery pack of 9.6V?
5 rechargeable battery voltage is 1.2V a, so with 8 AA rechargeable batteries get the output voltage is just 9.6V. Can replace the 9.6V single battery, such as to be more durable, as long as the capacity of some of the battery on it.
