Question for your 18650 builders. I know spot welding and nickel strips are preferred.
But. I am wondering if one should stay with the positive and negative wire gauge size for the output connector.
Example. My SLA 12v 20ah years. I always stayed with 8,10 or 12 copper gauge for my terminal...
The 12v demention layout is the only option as i would have to tear apart the bike again.
Cell level fuses are a option i am considering.
Since i would be making these packs. I would definitely be adding the option of mainance leads per pack along with direct charging. I am aware it is not...
Would be all at once as I would build each pack to replace the sla batteries.
I was googling and I guess it would be a 3 series and x parallel pack.
72 Cells in total. 3 in series with 24 in parallel. Thou I can't see that being about the same size or smaller.
72 cells x 10 Packs is 720 cells...
ive been trying to figure out how many 18650 cells you can fit in a 12v 20ah SLA dementions.
Length: 7.13 inches (181mm)
Width: 3 inches (76.2 mm)
Height: 6.57 inches (167mm)
how many ah could I fit in these dementions assuming i am not including a bms and a base voltage of about 10-15v
i...
Sorry for the delay. I have yet to trip my 50a breaker.
Thou I did have 4 controllers 1000w and 1500w fail on emmo bikes. 96v controllers. tried both at 96v stock acid and 108v both had died (resistance in the hub motor) while controller was attached to phase. As soon as I disconnected the...
Here is the 96v 1000w & 15000w Models
96v 1000w
Fet: IRFB4115 3329 2E 31
Caps: 160v 470uF
96v 15000w
Fet: IRFB4115 329P JS 21
Caps: 160v 470uF
Both have a cause of death. Blue phase tracers to fets obliterated. Exact same area as well.
Both where running 108v 20ah acid deep...
