Im not sure if this is an alarm im thinking of getting this https://www.banggood.com/BX100-Battery-Voltage-Tester-Low-Voltage-Alarm-Buzzer-For-18S-Lipo-Battery-p-1070002.html?rmmds=search&cur_warehouse=CN
Well… u can buy nicer one for 10usd… just find space to mount it later on
whats the difference
Thanks very much
Difference is quite big… I had that little buzzer, it gets annoying over time + not really practical to see all voltages visually… will take something like 10s to see whole pack voltage…
if u really want cheap, maybe get this one:
(when on sale, they are a bit cheaper… or just find another source for them)
Will help with calculating left range also… if u got any other Qs related to batteries, just ask

Some more options to look at:
(This one costs just 10 bucks… but i personally dont like the display… I think it had no backlight… which might be minus…
Actually, this one looks quite handy too:
Though I think it has no backlight (might need to install led diode manually)
Though I like that it has external led which starts to blink / shine once voltage is low…
This one also good… shows pack percentage too… cons: Doesnt have backlight…
I think wont find anything cheaper than that…
Might seem like a little investment but its worth it

Also on cheap side:
I actually read the back of the voltage tester I have. It is a voltage alarm so I will just use that for now thanks so much for all your help tho!
Important stuff like how to not burn your house down.
Don’t discharge your lipo any more. They are fine till you balance charge them. They are close enough in voltage the balance charger should average each cell just fine. Just a heads up with the low voltage buzzer. If you are accelerating hard with a pack that is lower voltage 30-40% left it will sag and buzz every time even When your battery still has useable capacity left.
How far will a 6S 10400mAh LiPo last with a dual motor setup
http://calc.esk8.today. Use this to input your specific parameters, then you will know all that there is to know young grasshopper.
Charging wise about +3h charge time with 50w charger at max amps (when 30% left in battery). So even more when pack is more depleted.
2A charge rate not much for 10ah pack… though see for yourself, maybe u gonna charge in evenings only and it wont cause any problems
Range… seems like 10miles for sure, maybe 12… check calc
