Fogstar Drift App (1 Viewer)

[headlight]

Anybody having problems with the app ?
I received 2 x 105AH Fogstar Drifts today.
I down loaded the app on to my phone but no matter what I do my phone just searches and searches and doesn't connect.
I have also down loaded the app on to my tablet but that won't connect either.
I have Bluetooth and location turned on on both devices and have uninstalled and re-installed the app several times on both devices but still no joy.
I can connect to other devices via Bluetooth no problem.

Update:
Went away on Friday for a 4 night break over New Year.
Victron Smart Shunt said the batteries were at 100% SOC.
Got to site, set up and no 12v power in the hab.
Checked the shunt app and it said 100% SOC and 13.4v.
Opened the Xiaoxiang app, as I can't connect to the Fogstar app, and it said, for both batteries, 100% SOC, 105AH , 13.4v and cell voltages of 3.558v on one battery and 3.458v on the other.
But I noticed that charge and discharge were set to off, which I hadn't done, so the BMS had turned them off ?
Unfortunately although the Xiaoxiang app will let you monitor the batteries it doesn't allow you to alter any settings.
So no battery power.
Luckily I was able to move to an EHU pitch so trip saved.
Yesterday I borrowed an iPhone off another motorhomer and downloaded the Fogstar app onto that and it connected to the app.
Great I thought, I can turn charge/discharge on and use the batteries.
No such luck as when I tried to turn discharge/charge on I got a message saying pack over voltage/cell over voltage and it wouldn't let me turn them on.
This even though the app is saying battery voltage is 13.4v and all cell voltages are below 3.6v so the battery and cell voltages are not over.
Pretty disappointed really.
I will ring Fogstar next week when they are open but I have a feeling these batteries are going back.

Hi
I have a fogstar battery and in the advanced settings (which I haven't changed and I appreciate you can't get to) the cell overvoltage trigger is set to 3.7V but the overvoltage release is set at 3.5V. I guess this means the cell voltage has to drop below 3.5V before the bms will let you turn charge/discharge back on?
Is it possible your charging system is overcharging eg not via a b2b on lithium setting?

B2B (Sterling) and MPPT (Victron) are set to lithium, 14.2v charge and 13.5v float, so neither should overcharge.

We have different batteries (mine is 230Ah underseat) and fogstar told me they use 6 different bms across their range, but the pack overvoltage limit on mine is 14.7V and reset 14.4V, ie way above what yours should be seeing. Worth sticking a meter on them with the engine running?

Already done that.
13.4v with and without the engine running and 13.6v on EHU.

It will be a dodgy setting in the BMS advanced settings

I've never been in to the settings though ?

I really am starting to appreciate the simple qualities of my Relion battery, no bluetooth, no access to the bms and no heater. It has just sat there for 6 years being a battery and looking after itself. I keep an eye on the charge level via my Victron app.

I am starting to get concerned about my new van which will need a larger under seat battery and these seem to come with built in bluetooth.

 

[headlight]

This what the Xiaoxiang app is showing as of now.

Same here with my KS Energy but it does have BMS & app but just to monitor not play with.

Interesting, the dealer was recommending KS Energy. I can’t afford to have a battery that shuts down because my Efoy fuel cell must stay powered at all times i) to know when it needs to cut in and recharge the battery and ii) to protect itself from freezing.

What version of the android Xiaoxiang app are you using I am using 3.1.1026 on Aolithiums that allows full control over all BMS settings including switching charge and discharge.

I’ve just tried the Fogstar app whilst sat here in the conservatory

it’s connected to the tv in the conservatory, Apple tv in my demo room downstairs and bedroom to upstairs

No idea just the free app with a logo of a blue elephant.
On the Fogstar forum I've been told that I need to use the paid for app version to be able to alter settings.
I'm not prepared to pay for an app when I've already paid for the Fogstar app.

If you pm your email I can send you a android copy of 3.1.1926 which is free, strangely the Fogstar app is also free on android.

 

[Raul]

Can you give a try with JK app? Jinkong and it does have a elegant on white background, the pairing is 1234, and settings access is 123456 pass.

Wow, disappointing. What a saga, I'm really interested in finding out how It ends.

Ours never shuts down

I assume you mean you paid for the fogstar app by buying the battery from them?

 

[Pausim]

Good to hear, I think that is decided then I will have them fit the KS Energy.

 

[headlight]

I assume you mean you paid for the fogstar app by buying the battery from them?

Yes, 2 batteries so 2 apps.
The app is obviously part of the purchase price of the batteries.

 

[Ian_H]

In the fogstar app I've just found a couple of 'release MOS' buttons that might help you if you get the app working. Under advanced settings (password req), calibration.

I’ve not paid for the Fogstar Drift app

it’s free from the app store if you buy the batteries or not and 1 app sees both batteries

Reviews not good on apple or android, others on android can't connect

 

[Just smiffy]

I wouldn’t have lasted this long with them, I would have sent them back already. There is obviously something wrong with them if most other people don’t have trouble with them, but I must say that after hearing people are starting to have problems they wouldn’t be my first choice now and way down the list when I buy a lithium battery…..

 

[Al n Val]

I honestly can’t fault mine, they are certainly on a par with my Super B’s in every way at a 1/3rd of the price and 3 x capacity

No brainer for me

What I meant was yes the app is free but it's development obviously involves a cost which I assume is built in to the cost of their batteries.

You also said 2 batteries 2 apps
