6 Frequently Asked Questions about “How many strings of 72 volt lithium battery packs are there”

What is the nominal voltage of a lithium battery?

A nickel-based battery has a nominal voltage of 1.2 V, and an alkaline battery has a nominal voltage of about 1.5 V. The other lithium-based battery has a voltage between 3.0 V to 3.9 V. Li-phosphate is 3.2 V, and Li-titanate is 2.4 V. Li-manganese and other lithium-based systems often use cell voltages of 3.7 V and higher.

How many parallel strings can a battery have?

The absence of any theoretical limitation to the number of parallel strings is borne out by the experience of telecom operators, and at least one battery manufacturer allows up to 16 parallel strings, depending on system voltage.3

What is a lithium ion battery pack?

Packs like these are normally spot welded together with nickel strips. Lithium-ion, or Li-ion typically refers to the overarching technology of rechargeable lithium batteries, but also specifically refers to the traditional cells built in cylindrical metal bodies. The venerable 18650 is one such cell, but a large variety of sizes and types exist.

What type of battery is in the top pack?

The top pack is an HV type. Lithium-HV, or High Voltage Lithium are lithium polymer batteries that use a special silicon-graphene additive on the positive terminal, which resists damage at higher voltages. When charged above 4.2V, most lithium batteries exhibit significant capacity loss and reduced lifespan.

What is a battery pack?

A battery pack is a set of any number of (preferably) identical batteries or individual battery cells. They may be configured in a series, parallel or a mixture of both to deliver the desired voltage and current. The term battery pack is often used in reference to cordless tools, radio-controlled hobby toys, and battery electric vehicles.

What voltage should a lithium ion battery run?

They operate ideally between 3.0V-3.65V, instead of the more typical 3.0-4.2V range of a standard lithium-ion chemistry. This, combined with a very flat discharge voltage curve, makes them ideal replacements for 12V lead-acid batteries in many applications, where four cells substitute for the original six.
