Fully Programmable Smart BMS with Bluetooth with Android or iPhone App. The charge and discharge using the same port. Smart BMS is designed for 4 series (4S 12V) Lithium (Lifepo4) DIY Battery Pack. 4 x 3.65 =14.6V Lifepo4 Chemistry battery Protection functions : This BMS is designed with a high quality IC chip specially for lithium battery protection. High detection precision degree on over-charge, over-discharge, voltage balancing. Protection of over-discharge and over-current detections and delay times in detecting process. Protection against over-voltage when charging Low temperature charging protection a -1c. BMS with Precise SOC calculation with SOC function with automatic learning. Automatically charge battery function or static balance function for the battery system 4s BMS. Mobile phone software to manage the detecting the battery working status and some parameters setting over wireless bluetooth. Lithium Ion Technology: Deep cycle lithium ion batteries have exceptional longevity since they manufacturing by LiFePO4 Cells with higher energy density, more stable performance & greater power, letting you use the battery more freely. Lifepo4 are more cost effective, so when factoring time and cost into your purchase. The protection board has various protective functions for charging and discharging, such as overcharge protection, over-discharge protection, short circuit protection and over-current protect battery smart balance. Choosing a protection board and applying it appropriately is vital to the longevity your batteries. It is ideal for battery management system BMS lifepo4 battery DIY and RV batteries with a wide rage of battery applications. 4 Cell 12 volt – Lithium Lifepo4 – Build a high capacity LifePO4 battery from individual cells. BMS supports up to 200 amp continuous charge or discharge current. Perfect for your high current applications. Low Temperature Charging cutoff – Prevents damage to LifePO4 cells when the temperature is to low to charge.
