How to choose DALY BMS:
The type of BMS must be consistent with the type of battery pack.
Li-ion Rated voltage 3.7V
(Over charge voltage 4.25V,Over discharge voltage 2.7V).
LifePO4 Rated voltage 3.2V
(Over charge voltage 3.75V,Over discharge voltage 2.2V).
Wrong choice consequences:Burning BMS and battery. Not fully charged, not fully discharged, and the BMS is damaged.

Number of battery strings:
The number of strings of the BMS must be consistent with the number of string in the battery pack

Continuous current selection:
Power ÷ (battery string number × excessive voltage) = Maximum output current, the selection of the protective board should be greater than the maximum output current (it is recommended to multiply by 1.5 ~ 2 times)
Take the maximum output current on the 400W power of the Li-ion 13 string batteries as an example: 400W ÷ (13 × 2.7V) = 11.39A. The actual error of the motor may reach 1.5 times, so the actual maximum output current is 11.39A × 1.5 = 17.08A, in view of the inheritance current of the protective board is greater than the output current of the battery, it is recommended to choose a 20A BMS.

Wrong choice consequences:Larger current is better and smaller current will broken the BMS.
1.More High-end BMS: Applicable to 3~24 strings of Li-ion/LifePO4 and other batteries in the range of 30~500A.
2.Focus on Lithium Battery Safety: Over charge protection; Over discharge protectionOver current protection: Short circuit protection
3.Innovative Heat Dissipation: The unique wave -type aluminum has greatly improved the heat dissipation area and efficiency.
4.Snap-on Connection Cable: The BMS is connected with the cable in a snap type connection, which is convenient to insert,
and is firm and secure.
5.Preset Screw Positioning Holes: BMS has screw positioning holes, simple and clear, easy to assemble.
Note: The 100~500A version has positioning holes.
6.High-end ABS Injection Material Top Anti-drop: The appearance adopts the glue injection sealing process, and the hardness has passed the drop and extrusion crash test, and the impact resistance is beyond imagination.
7.Hardware BMS comes with 45cm cable in length
