LiFePO4 BMS 48V 16S 200A Smart PCB Battery Protection Board Battery Management System with Balance Leads Wires and Wireless Module for Lithium Iron Phosphate

Does very well balancing cells. Not sure about charge limiting or discharge limiting, but I purchased this to balance my Li-Fe P04 cells and it keeps them within 0.1 volts. Built very rugged and seems of good quality.

I bought 2 12 Volt 100 AH Lifepo4 Batteries at a Great price after about 2 months 1 quit working after contacting the company they sent me a new Battery I was told to do whatever I wanted with the other battery I cut the case open and tested everything ordered this BMS changed it out and the Battery started working immediately I was able to use the Balance lead wiring just plugged it in and replaced the main power leads working Great. Heavy made and easy to use it's a quality BMS

this is the 4th i've purchased works well

My BMS bluetooth module went bad, does not work the way it is suppose to. Randomly shuts off and I have to power cycle it, unplug and plug back in, to get it to work for just a few hours then off again.VNSZNR claimed they could not find my order although I sent proof many times (I knew this was going south at this point), they just kept gaslighting. Maybe they will see this review of verified purchase here.VNSZNR customer service was very unhelpful and kept gaslighting my issue, they would not replace the bluetooth module under warranty to determine if that was the issue, told me to buy one and replace it myself? No 36mo warranty, that is a false claim in the listing and I am reporting it to Amazon. VNSZNR claims nothing wrong with my bluetooth so I guess non functioning bluetooth that randomly shuts down every couple hours, even with the 65535s setting, is normal based on poor broken record customer service. I am an electrical engineer. Been working with Daly bms's for years, very disappointed in this side company for Daly, Maybe they dump QC seconds. Who knows. Well VNSZNR here is your earned review. I gave you so many opportunities to do the right thing. You failed.I recommend 1: a JBD BMS with built-in Bluetooth or 2: a 100Balance BMS with integrated Bluetooth with wifi option.

I needed 4 for this project , had to go to 3 different suppliers for all four. well built , put 40 amps through this bms and did what it was suppose to do .

I had a good working one , till I arched it on top of battery , I'm replacing it with this one , it works

I initially gave this bms a poor rating but the issue was from my own doing. I had the bms wired correctly but failed to notice the small on/off button on the Bluetooth receiver. I was contacted by customer service and they made me aware of this button. Once I hooked the bms back up and pushed the button, it worked flawlessly. The product works great and customer service was even better in reaching out and helping me fix MY mistake.

Seller gives an irrelevant response indicating that they have no intention of honoring their warranty: The 150A BMS has a .75V drop across the battery in/out terminals when under a 50A load, dissipating 37 watts and getting very hot. The seller implies this is normal. Their own 100A BMS in the same conditions only drops .09V dissipating 4.5 watts
