Re: Increasing Battery Voltage 36 to 48V

Yes i think the c rating of cells was not high enough and replacing the cell which i'm finding very hard to find the same size, Best as perhaps as this batteries weight made bike very heavy ,,, I buy another battery with higher continious current draw but an expesive way to go. If in an effort to re...

Re: Cyclone motor problems

Thanks all ,,, & that e bay controller will be last resort with its cost hoping he could describe how to wire to cyclone s complex wires. I've now proved it was the cells to the 36v battery breaking down as well as the controllers LVC . Even thrashing 4 SLA batteries as 48v they would go down to 30a...

Where are you Zack as i thought rewinding would cost more than new. I am NZ .

Br paco offered me motor for 100usd ----thi...

Re: Cyclone motor problems

well on the hill motor cut out , lights went out so its battery , shorted out bms then still it happened . I think i've had the 2 problems at once cells breaking down & that heat switch so i'll get 3 12v sla batteries yes with them. If the hill had a cliff I'd thrown it over.---Thnks again.

Will not start again for a period but with disconnecting battery will spark & start again.Voltage does not drop below 34v so its not LVC. With shorting out BMS does the same ...

My first troubles with lithium batteries were BMS being the cheapest was only for low current & needed a higher current BMS . I've replaced heaps because of this.

Re: Without BMS

I wouldn't leave any battery more than 4-8 weeks before recharge. I'd like to know this guy without BMS to see how long his cells all last . He Had what he called 1500w 48v I thought bafang mid-drive didn't get that big . Testing each cell when charging seems nut when a BMS can do that . I've made u...

Re: Motor shuts down

The only thing besides a damaged motor with not showing any burn to me it could be that the LIFePo4 battery suddenly cannot keep voltage high enough for the LVC . this I have had with old batteries & did not happen suddenly. I can only assume that the 3 & 4 SLA batteries i've tried ,not being ban ne...

thanks for reply . I did suspect LVC shutting motor 48 v newly charged sla battery cuts out at 42v & at 36v cuts out at 31v does this sound right ? as I've had this problem before with cyclone controllers but classed it as being the batteries being very old .

On the 36v was running every day with only the BMS shutting down when using motor too much. Have today hired 3 12v...

Re: What kit to choose?

Depends how mechanically minded u r & if you can go so high in wattage motor without having licenses etc for the high wattage. Hub motors are simple to install but need to be high wattage to get the performance up hill or top speed as pedaling speed is like max 40k p h. Eclipse is same as cyclone bu...
