Quick reference

Printed on the cover Configuration Table as "Balancing Current ... 2A" (checked, this SKU's configuration); the same figure is printed on Jikong's own product page as "Balancing Current ... √2A".

Location: Cover page, Configuration Table

Jikong's own product page prints "It also integrates advanced active voltage balancing to monitor the voltage of each battery cell in real-time and improve battery life through active balancing management" and lists "Active Balancing" as a feature; the datasheet's Section 5 groups the balancing figures under the heading "Active Balancing".

Printed in Jikong's V19.0.3 specification as "最大充电电流 (Maximum charging current) ... 20P 200" A in the basic parameter table (section 4.1); section 3.16 adds a charge current limiting function that holds charging at about 10A after a charge overcurrent. Revised on 13 October 2026: this field held 25 A, taken from the V1.0 specification's Section 5 line "Maximum Charge Current 25A" under Pack Overcharge Protection, which is a factory default protection setting the user can configure, not the board's rating; that V1.0 setting is kept here as history.

Printed in Jikong's V19.0.3 specification as "最大持续电流 (Maximum continuous current)" 200A for JK-PB2A16S-20P (section 2.1) and "最大放电电流 (Maximum discharge current) ... 20P 200" A (section 4.1); Jikong's store page prints "Continuous Discharge 200A". Revised on 13 October 2026: this field held 150 A, taken from the V1.0 specification's Section 5 line "Maximum Discharge Current 150A" under Pack Overdischarge Protection, which is a factory default protection setting the user can configure, not the board's rating; that V1.0 setting is kept here as history.
