How do you make up your own lithium ion battery?

How do you calculate the number of connection batteries in series or parallel of a set of lithium battery need?

Answer 1: simple, increase voltage series, in parallel to increase capacity, ternary lithium standard voltage 3.7 v, 4.2 v, three string is 12 v, 48 v requires four three strings, but electric lead-acid the battery58 v most charged, so lithium electricity also need to 58 v or so, so you need to 14 to 58.8 v, 14 multiplied by 4.2, about 3.4 v lithium iron full of electricity, need four groups of 12 v, 48 v requires 16 series, and so on 60 v requires 20 series, parallel model with capacity, 10 ah batteries two parallel is 20 ah, 48 v ternary lithium requires 14 + 14 pieces of 10 ah batteries, final 14 block parallel good series of 48 v20ah lithium batteries

Answer 2: actually, it is very simple, such as 48 v refers to voltage, usually the ternary lithium battery refers to 48 divided by 3.7 13 and 14 chain are calculated so 48 v, thirteen string using the 54.6 v charger, 14 series use 58.8 v charger. As for 20 ampere hour refers to the capacity of the battery, if it is only 18650 batteries every capacity of just 2000 ma, this is 2 ampere hour each, ten batteries and together is 20, the battery is for the whole bunch of times 10 to 14 batteries = 140 batteries only.

60 v is the same truth, usually 16-17 string are 60 v, so 60 v 20 ampere hour single cell capacity is 2000 ma, is 16-17 times the 10160-170 batteries. See here should be clear

Lithium iron batteries is divided by the total voltage of 3.2, such as lithium iron 48 v refers to 15 to 16 series of algorithms are the same, just than ternary lithium strings of lithium iron batteries, and a lithium iron and ternary lithium charging voltage is different also, when you buy more to communicate with the boss.

Do we need to connect the batteries in parallel or in series?

Answer: first in parallel, and then in series.
