What to confirm before you order
A matching model name is not a match on its own. These are the values that decide whether a board fits the pack, and the sales team needs them to quote the right unit.
- Battery type and cell count: LiFePO4, lithium-ion or LTO, and the number of series cells.
- Continuous and peak current: the charger, inverter and load currents the pack must carry.
- Hardware revision on the label: the same model name can ship in different revisions with different files and ports.
- Communication needs: Bluetooth only, or USB, TTL, RS485 and CAN to a display, PC or inverter.
- Physical fit: enclosure size and terminal position, especially when replacing an installed board.
Send the label photo and the readings you already have, and JKBMS confirms the model, revision and port before recommending a unit.

How to buy: single unit, project or volume
Add to cart and pay
Product pages that show a price can be ordered directly with PayPal. Confirm the variant label matches the configuration you need before checkout.
Get a checked plan first
Send the installed model, hardware revision, battery, inverter and target function. The team confirms compatibility and proposes the units, cables and accessories the system actually needs.
Ask for a discounted quotation
Volume pricing is calculated from quantity, product mix, packing method and repeat-order potential, and returns as a formal quotation from the official sales team.
Verify the quotation
Confirm the seller and the offer against this domain and the official sales address zhou@jkbms.net. A quotation that cannot be verified here is not an official JKBMS offer.

Buying questions answered
How much does a JK BMS cost?
JK BMS boards start at $39.68. Every product page lists the published price for each configuration, so the number you see belongs to the exact model, cell count and current rating rather than a category average.
Is shipping free?
All products ship free at checkout except the two battery enclosure kits. An order that contains a battery-kit or 6u-battery-kit carries a flat $100.00 shipping fee regardless of destination, charged once per order even when it holds several kits or a mix of kits and other products.
How quickly is an order dispatched?
Orders are prepared for dispatch within 3 business days after payment clears. Transit time depends on the destination and the carrier route chosen for the shipment, so it is confirmed on the quotation rather than published as a fixed number.
Are these original JKBMS products?
www.jkbms.net is the official factory website for JKBMS Electronic Technology Co.,Ltd. Product pages, specifications, firmware and manuals published on this domain come from the factory record. Use zhou@jkbms.net to verify a quotation or a supplier claiming to represent JKBMS.

Send the pack details and get a compatibility check
Model, hardware revision, cell count, current and destination are enough for the sales team to quote the right unit and the accessories it needs.
