battery indicator help

[billyboya]

hi all I have this battery meter on my electric bike what I fitted myself. but I am a bit confused with all the readings like for instance Ah which I believe goes up to 16 can anyone here help

Ah shows the capacity you have used from your battery, if you use a 30ah battery it will show 30ah or near damn it if you drain it fully. If you switch it off it will zero again,
Top left tells you the amps drawn when current flows.
Top right is self explanatory, Battery voltage.
Bot right is power drawn in Watts output.

Wow many thanks for your reply I do believe my battery which said

24v 350w battery 24V 15ah electric bicycle battery 24v 16ah Lithium ion battery pack with 15A BMS and 29.4V 2A charger duty free

so is this battery 16Ah as it says 15Ah Im a bit confused. so how far in miles can my battery go

here are more specs

24v x 16 Ah = 384 Wh

You will be using a certain number of Wh/km (mile if you must...), 10 Wh/km is a pretty common number for an average rider so you will get about 38 km from your fully charged battery.

I am a relatively strong rider and I get 7.5 Wh/km on my upright pedelec but 5.25 Wh/km on my trike. Using various tables and calculators found on the internet that means I produce between 150 and 200 Watts continuous output to which you add the assistance provided by the motor.

 

[billyboya]

so that's roughly about 22 to 25 miles that's good to know then

so a 48v would get me 76km about 45 to 50 miles

many thanks for your reply

You are probably confusing capacity which is 16ah with the continuous discharge rating of the battery which is 15 amps both are different ratings. The cells are 2a rated each.

384wh at respectable 12wh/m will give you about 30 miles range at low assist level. The lower the assist level used the more range you should get, though with hills best to use higher power to get up the hills easier and quicker.

Ok well its still good to know I can get a good 30 miles out of bike. so now I know what Ah mean which mine has 16 Ah so say the meter was reading 8Ah that means i have used 1/2 my battery up.

once again many thanks to all
