Scope

What is sold here, and who makes it

Two brands appear across the catalog and they cover different hardware. Knowing which one a product belongs to is usually enough to know which constraint decides it: the enclosure is chosen against the cells, the BMS against the load and the inverter.

What the catalog covers

  • JKBMS smart active-balance BMS boards, in the JK-BD, JK-PB, JK-B1A and JK-B2A families
  • Displays, monitors, communication modules and inverter cables
  • JKESS LiFePO4 enclosure kits in caster and 6U rack formats
  • High-voltage control hardware and configured C&I ESS cabinets, both quoted rather than checked out

Before paying

Six things worth confirming

None of these are unusual requests and all of them are cheaper to settle before an order than after. The last two apply automatically at checkout, but they surprise people often enough to be worth stating here.

The order is the configuration you selected

On a multi-option product, the selected variant is what is charged, picked and shipped. Confirm series count, continuous current and any bundled display before paying rather than after.

A quotation should name its exclusions

A quote you can check states the exact model code, quantity, destination, who pays freight and duty, and what is not included. If it lists a product name and a total, ask zhou@jkess.com for the rest before comparing it to anything.

Shipping is a destination rule for the kits

The three enclosure kits ship free to the EU, at a flat USD 150 to the United States, Southeast Asia, Japan, South Korea and listed Middle East markets, and need a manual freight quote elsewhere. Other products currently ship free worldwide.

Euro-area buyers are billed in EUR

Prices are set in USD, and buyers in the twenty euro-area countries are charged in EUR so that local bank payment methods are available. The figure in the checkout summary is the figure charged.

Compatibility is confirmed against your system

Series count, continuous current, balance current, protocol revision, pinout and installation conditions are project-specific. Send the inverter model and pack details and they can be checked before the order.

Documentation is filed by model family

Manuals, specification files and firmware notes are published by family rather than by brand token, so search the family segment of the code rather than the brand name.

On brand names

JKBMS, JK BMS, JIKONG and JKESS

JIKONG is the romanised company name and JKBMS is the product brand, so both are printed on the same boards. JKESS names the enclosure and energy-storage hardware. None of the spellings identifies a specific part, which is why an order should be placed against a model code and a configuration rather than against a brand name.

FAQ

Questions this raises most often

Who am I actually buying from?

BatteryBoxKit is a stocking store and integration resource operated by JKBMS Electronic Technology Co.,Ltd. Orders placed here are fulfilled from that stock, and quotations are issued by the sales team named on this page.

Who manufactures the hardware sold here?

JKBMS smart BMS boards and accessories are manufactured by JKBMS Electronic Technology Co.,Ltd. JKESS enclosure and energy-storage hardware comes from the same company. This site stocks it and publishes the integration data needed to design it in.

How do I check that a quotation is genuine?

Reply to it from the address it arrived at and confirm the model code, configuration, quantity, destination and total against zhou@jkess.com or +86 131 6282 8868. A genuine quotation restates all of those and names its exclusions; a payment request that arrives on a different channel from the quotation is worth a phone call before anything is sent.

What happens if what arrives does not match the order?

Contact the sales channel that issued the order with the model code on the board, photographs of the label and the fitted ports, and the order reference. Return, warranty and support terms are published on the policies page.
