I used my DC BST900w Boost Converter to charge my e-bike , we had a storm this weekend that blew my bike away while the charger was still plugged in and pulled the charger into some water
now I thought I had dried it all but forgotten to empty out the water out of the socket of the controllers...
my main concern is these batteries should not even be putting out his many amps to start with, as rated as 5amp max in a 4p setup which would have meant 20amps max and with my 5p setup 25amp max, bright side new BMS allows me to set the max discharge
unless I give up on the glass 1amp single...
it was a manufactures battery pack that caught fire
how ever I believe I hit another snag , with the new pack being 16s5p , I don't have enough P to flow 40 AMPS through 5x 1 AMP fuses
so much for the motor only being 480 watts it spends most its time around 20 amp draw on the flat and...
after my 4 yr old battery back went up in flames I am going to be doing this
a BMS wire got a wee bit too hot and was the 1 and only wire that sat across the ribbon cable
needless to say things started shorting
so whats the best fuse that can handle mountain bike bumps ...
Did anyone think about aluminum strips?
should be a better conductor than nickel and not have the same tarnishing issues as copper?
as it's not being welded it should no oxide...
I possibly should have mentioned 13s 18650 battery cells with BMS
but yeh looking for a DC Adjustable Constant Current Buck Voltage Regulator step-up that can have 48v input and does 48 - 90v output
something like this but step up...
my lipo chargers keep dying and I have a 48v 20kw 500ah battery backup bank at home
how can I safely charge my batteries directly from that bank?
today I was desperate enough to disconnect bank and use the bank's charger with the smallest fuse I could find being 5A and charged my 13S e-bike...
Another thing that can be done is have an larger shocky installed this means you can make an deeper battery case
the bike's tire / battery case clearence's (from memory )
( the original 160mm susupention on my bike had tire rubbing on the stock case )
180mm wound down to 170mm solved it ...

I am actually hoping the speedict will work out cheaper due to the moble phone integration
unfortnatly I shouldn't mention any of the details I have obtained via email as nothing is set in stone yet
but from the...
Their is nothing stopping you from buying another battery pack and running them both parallel
or just one pack too destination and switch to the fresh pack for return ..
the only desision is how you want the asthetics
you could either build an tall batterypack or just mod the second pack to...
Really craving speedicts new toy
Think

but with MORE !!!
seems like speedicts going future proof, you can have as many cells as you like and set the cell voltages how ever you please
Cheers for the shunt idea ( that pic is definatly worth 1000 words )
However I am going to solder in an switch to by-pass the shunt when I want the extra power
I just need to deside if I will use an relay or heavy duty switch
Well I bought the 36v-100V to 5V USB power adaptor and will make an DC-to-DC converter to power Winkku Bicycle Lights Mirror & Indicators
now onto my next line of thought
(downside that speedict is limited to around the 80V range as I wanted 96V )
What I am now wanting to know is it...
