has anyone ever found a place for replacement motors for these ?

has anyone modified these to do 48v (4x units together ? )

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...

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 ...

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 http://www.foundingpower.com/en/Products/Smart_BMS/20121202100.html 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...
