## What is Fogstar Drift?

The Fogstar Drift intelligent battery management system is connected with the active equaliser via Bluetooth. Our app, when used with the Fogstar Drift Leisure Batteries, will allow you to monitor your battery status, collect and store information in real time, process battery data, exchange information with external devices and monitor the overall safety of your leisure battery at all times. App functionality; 
1. Displays real-time voltage, current, power, internal resistance and other parameter values in the form of dashboard and digital display 
2. Displays the real-time voltage and alarm status of all single cells. If the reported parameter triggers the alarm value or protection value, an alarm will be prompted 
3. Compares the data of each cell, including the voltage difference, maximum cell voltage, minimum cell voltage, and overall balancing of the cells 
4. Creates a cell temperature warning for; over-temperature, short-circuit, over-voltage, under-voltage real-time alarms and keeps a record of all alarms that occur.

## Key features

- Real-time battery parameter display
- Single cell voltage and alarm monitoring
- Cell comparison and balancing data
- Temperature and critical parameter warnings
- Historical alarm records

### 3/5 — Could be better

*2025-05-28, version 4.2.0*

Works okay but would like to see trend features for charge & discharge over a period

### 2/5 — Could have been good.

*2025-05-10, version 4.2.0*

Shows the basics, but as far as history goes, once the app is closed or the phone screen goes off it is lost.  Also anyone with a phone or iPad can access your battery and switch it off if they wish.  Needs password protection!!

### 3/5 — Annoying app

*2025-03-18, version 4.2.0*

Although the App does what it says on the tin, it really hasn’t been thought out, how hard would it be to have an option to just show Fogstar devices, in a marina you pick up 100’s of devices and it takes an age to find your own batteries, switching between 2  arteries is clunky. I just hope the BMS software is better thought out and tested. Beta state!

### 3/5 — Why?

*2024-12-12, version 4.2.0*

Wondering why on the first iOS screen it says , please don’t connect to cell phone Bluetooth. Can’t see why this is an issue??? Am I missing something. Must it then only be used on iPad?  Or Mac’s with m series processors.

### 2/5 — Barely adequate app

*2024-09-22, version 4.1.9*

Fogstar battery appears to function as intended, the app is barely adequate. It needs to be manually connected to the battery every single time it loads, it loses connection instantly when in the background requiring sorting through a list of all Bluetooth devices in range (a list which jumps around as new devices are ‘noticed’). There is no history function, which may be a BMS limitation but the irritating way of making a connection is down to a poorly coded app.

### 1/5 — Unusable at times

*2024-07-07, version 4.1.9*

Not impressed - trying to work power tools on a remote job site with two £800 batteries - and when the app decides to play up you simply can’t turn the battery on! Needs major work and disappointing why it’s been this way the several months I’ve had it.

### 3/5 — App needs improvement

*2024-04-10, version 4.1.8*

In my experience, including having used other apps including xiaoxing bms app the following could be improved:
1. Fixing the pop up that shows up too frequently when the app is running in the background. It is extremely annoying and unnecessary.
2. Having to scroll through a list of discoverable BT devices to find the battery is a chore and the list refreshes so fast you end up tapping on some other device by mistake which can take a while to go back and find the battery only to make another mistake! 
3. If you are using accessibility features such as  larger fonts, bold fonds for visibility, the layout gets messy with some icons getting cropped from the screen instead of adjusting proportionately to the screen zoom level.
The batteries are great, high quality. It would be nice for the app to compliment the standard set by the batteries.

### 2/5 — Useful but plenty of room for improvement

*2024-03-21, version 4.1.8*

The app gives a useful insight into the battery status & health however as other reviewers have said there are plenty of annoying features like listing every Bluetooth device, the loss of BT connection when the phone screen locks or the app goes into the background & the battery status history graph only reflecting the status for the duration of the connection.

### 4/5 — In need of improvement

*2023-12-06, version 4.1.7*

App seams to work well with plenty of information on the battery health even the individual cells within the the battery connected. What let this down massively is the inability to change anything within the app like individual views of setting a custom display of the information that I’m interested in as a user. Plus little things like maybe a widget on the Home Screen so user can monitor whilst doing other things instead of have to load the app every time.

### 3/5 — Needs work

*2023-10-22, version 4.1.7*

The initial connection seems clunky , I have 2 batteries and have to tap on one to get both of them up and running , I then have to tap on which battery I want to view , I’ve also just noticed that if I turn off the discharge it also cuts out the charge too , could be an app fault or battery fault I guess , the list of Bluetooth signals is a bit annoying , as is the unwanted battery connect signal that pops up on screen lock , I do like the battery status main screen though , tidy and well thought out
