Description: 【Built-in BT】 No need for an additional BT interface, All types of JK BMS have built-in BT [App Download] Scan the QR code on jk-bms to download the app 【App Connection】 The connection password is 1234, and the authorization password is 123456. 【Active Balance】All types of JK BMS are actively balanced 【Automatic identification】It can automatically identify battery properties, and supports ternary lithium batteries, lithium iron phosphate batteries, and lithium titanate batteries. 【One-key setting】 You can set parameters with one key on the app 【Overshoot Protection】When the voltage is higher than the set condition, charging will be automatically stopped to protect the battery 【Over-discharge protection】When the voltage is lower than the set condition, the discharge will be automatically stopped to protect the battery Note: All BMS support RS485 by default, please purchase 485 module separately if needed. If you need the CAN version, please contact the customer to purchase. Please note that the CAN version needs to be ordered separately and is not built into every BMS. The SKU write that it supports CAN / RS485, but it is not built-in. 【Free screws 】The 100A/200A/300A version of the BMS will receive screws free of charge, see the SKU image for details. FAQ about the selection of JK BMS (1) What is the same port and what is the split port For example, 20 strings of 64V100A protection board, the same port means that your charging negative electrode and discharge negative electrode are connected to the same point (P-) of the protection board, and the charging and discharging negative electrode share an interface, so his charging current and discharge current are the same 100A. The split, just the opposite, the charging negative electrode (C-) and the discharge negative electrode are separated (P-), connected to different points of the protection board, so the charging and discharging current will be different, discharge 100A, charge 100A. (2) The relationship between battery capacity and protection board current The size of the battery capacity is not directly related to the current size of this board, mainly looking at the continuous current, that is to say, the greater the current limit of your controller, the larger the continuous current of the selected protection board, which is not directly related to your battery capacity. (3) What kind of charger should I choose? Lithium batteries must be charged with a charger dedicated to lithium batteries, do not use lead-acid battery chargers, charging with lead-acid chargers may cause high voltage breakdown of the protection board MOS tube, resulting in overcharge of the protection board is not protected. Tieli battery charger voltage = number of battery strings× 3.65V; ternary battery charger = number of battery strings× 4.25V. (4) How much current should I choose to protect the board? The current of the protection board depends on the current limit of the controller, and the current limit of the controller depends on the power of the motor, for example, the motor is 64V, 1000W, then the current is 1000/64=15.6A. At this time, the current limit of the controller must be greater than 15.6A, and the current limit of the protection board must be greater than the current limit of the controller. In practice, there must be a margin in the selection process.
