Printed on the datasheet cover as "Model: JK-PB2A16S20P"; Jikong's own product page prints the same code with a hyphenated variant "JK-PB2A16S-20P" in its page title.
Printed as "成品重量 (Finished weight) 1000 g" in the basic parameter table. One table covers the 10P, 15P and 20P boards and prints one size and one weight for all three.
Printed as "Supported Battery Types LiFePO4, NMC, LTO" (remark: "All parameters are for LiFePO4") and "Supported Series 8~16, 7~16, 14~16", the three series-count figures printed in the same order as the three chemistries.
Printed as "保护板尺寸 (Protective plate size) 300*100*24 mm" in the basic parameter table; the figures are not labeled by axis, so they are stored in the order printed.
Printed as "Heating Function Yes □No (Definition: During charging, if cell temperature is below -20°C, heating is enabled until -10°C (temperature can be configured))"; no heating wattage is printed.
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".
The datasheet's cover configuration and its own Section 5 print different balancing currents
The cover Configuration Table (this SKU's checked configuration, also printed on Jikong's own product page) checks "Balancing Current ... 2A". The same document's Section 5 Specifications table separately prints "Maximum Balancing Current 1A" as a generic factory-default/configurable figure, not specific to this SKU's checked box.
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".
1 A
Printed as "Maximum Balancing Current 1A" (factory default, configurable) under 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.
