Re: Need HELP with battery pack design for a EVG LEE IACOCCA e-bike

A bms should match the cells ability to deliver amps and also match the controllers demands. I think the original motor on a Lee Iacocca was a brush motor we now have brushless motors that are much more efficient. Do you have a spot welder for the battery ? Do you know the amp demands of the control...

Re: Need HELP with battery pack design for a EVG LEE IACOCCA e-bike

You can use a BMS or just put a set of sense wires and get a sell monitor for $10. It's great that you have 10p as you can use it as a 18 or maybe a 20 amp hour battery. So 10s ? Get all parallel strings to the same voltage manually before BMS . If no BMS you will be the BMS to monitor high voltage ...

Re: Looking for "new" used bike for electric conversion

On some mountain bikes they don't leave enough room for a nut on the rear wheel by the derailleur make sure there's enough clearance by the derailleur that you can put a nut on your axle. Then make sure that you have enough room between the rear wheel and the Steep seatpost for your controller some ...

Re: Motorcycle starter battery

1p ? Maybe 2p or ? A123 are great batteries and are a great choice for a 12 volt starter system as 4p. Bms ? Is this a road bike dirt bike scrambler ? Buy the cells with pre spot welded nickel strips to solder to . Is better than soldering and heating up the cell. A wet sponge will help cool down af...

For phase wires I have found 4mm bullets great. For speed and ez use after the 45watt iron heats up.

Re: Melting wires

So I'm not hearing a lot of support for the three wire yellow phase wire block with special nuts and ring connectors coming on the more inexpensive kits. Somebody must be using this at 3000 Watts ? Or 5,000 watts.

3.5v is full for lifepo4 there is very little capacity above that. 3.8v is something it could tolerate. But the SLA charger doesn't disconnect if goes into trickle charge best to charge it then unplug it.

I have had problems with Anderson's sometimes working good some ain't worth the hassle. Gold-plated bullets you see what you got you can feel it.

Re: Melting wires

I use crimp and solder on all signal wires as some are only 7 strand 24 gauge.My phase wires are 4mm bullets so need soldering and my battery wires are 5.5mm bullets that need soldering. Where does that leave me ???

Re: my 18650 frame pack build

Maybe there was a small air gap between the stiffer pos. End with mutli strand and solder combo. Giving a spark gap blow out. Maybe hold down with a chop stick if you have a third arm with hand attached.

Re: DIY battery pack bms question

Balance the pack manually do not rely on that poor little BMS to balance out of balance pack. It's to help keep a balance pack in balance at end of charge.
