...BMS battery protection system】： DJLBERMPW LiFePO4 battery it built-in BMS,It prevents the battery from charging at temperatures above 75℃，It can prevent over charge, over discharge, over current, short circuit and so on。Operating temperature: Charge at 0℃-45℃.
4.【Capacity expansion】： DJLBERMPW LiFePO4 battery is supported in series or parallel connection, in series, can be up to 4 batteries in series, Parallel connection has no upper limit, but we do not recommend excessive parallel connection, suggest no more than 4pcs in parallel，it has an impact on the overcurrent protection value of the battery protection plate..
5.【Long service life】： Lead-acid batteries can only use 200-400 cycles, and our lithium iron phosphate battery can cycle 4000+ times, and in the state of full charge and full discharge can cycle more than 1500 times, the service life of lead-acid battery is 3 times..
【Matters needing attention】：Please charge the battery before using it when you receive it. For transportation safety, our battery only has 50% power when it leaves the factory, and it may be out of power in your hands. Therefore, please charge the battery before receiving it. The recommended voltage and current of the....

Can be used for motherboard 4pin interface, used for PWM speed control and multiple cooling fans, expansion and expansion of motherboard 4pin interface, such as CPU fan plug, chassis fan, etc..
Easily realize the parallel connection of 4-pin PWM temperature-controlled fans, so that the fans can achieve a quieter effect and better heat dissipation..
High-quality black mesh extension cable, unique design, adjustable speed, realize one power supply for two fans..
Support PWM function, increase airflow, reduce heat accumulation in the frame, and meet all your control needs, thereby extending the service life of the motherboard..
High density black casing, low line visibility..

Best defense against unknown refrigerant and the risks associated with unknown refrigerant is a refrigerant identifier.
Contaminated refrigerant can wreak havoc on any R134a recovery recycle and recharge machine.
Protect your A/C service equipment and know whether or not you have acceptable R134a refrigerant before servicing the vehicle.
DiscovR refrigerant identifier notifies you when the system contains excessive air.
Pass and fail lights clearly show if refrigerant is pure enough to be recovered.
