Re: New 14s battery pack, US18650VTC6 vs NCR18650GA

wow big heavy battey for a e-bike :shock: why?
cells in the 3000+mah range age way faster after 60 till 100 cycles they already degrade.

8P 9P pack 40/50A max discharge you be fine with the Samsung 29E are the Panasonic PF cells.

Re: BMS broken, damaged cells, or both?

als je de zelfde bms hebt als in je link met youtube filmpje is het super simpel om juist te monteren....begrijp je dit niet dan zou ik zelf niet de gok nemen om aan lithium accu,s werken.

die bms monteer ik je in 15 minutjes incl nieuwe krimpfolie.

Re: Storm Bee electric dirt bike

Hopefully tomorrow. 12F or 24F? 12F is not an easy to wheelie (Only 250A Phase) but depends on battery voltage ,your engine type and final ...

Re: Sur-Ron - New Mid drive Bike

The name Boom Bee sounds nice 8)

will the boom effect come from a 4 to 6kwh battery that can handle a maximum of 150 to 250A discharge?
or will it become a really serious escrosser with a capacity of more than +10KW and good range ? if so then it will cost more than € 8000,- I assume

Re: Nucular Electronics owner's thread (setup infos, FW updates, links etc.)

I run the stock battery and the battery gets hot! done hundreds of tests and knows how the pf performs. As a joke, I will sometimes convert my test set-up so that it can be discharged with a continuous current of 50 Amps (4500+ Mah discharge per cell for stock sur-ron battery)... i can also discharg...

Re: Nucular Electronics owner's thread (setup infos, FW updates, links etc.)

2,81v/cell is pretty deep. stock battery cuts off 3.0v ?! looks like you are just guessing. after this discharge you need to charge it with something that reads wh :P i bet my left ball that using a satiator your charge will end up ~1800wh 180-200wh difference is the ~10% we are talking about.... 6...

Re: Nucular Electronics owner's thread (setup infos, FW updates, links etc.)

battery completely discharged and according to the display I have consumed 1603Wh, had it set to 1750Wh (2750Mahx11P) apparently the Panasonic PF cells in real life under a load between 5 and 10A discharge per cell around 2520Mah or the measurement is not 100% but I don't think it's in very much.

Re: Nucular Electronics owner's thread (setup infos, FW updates, links etc.)

I think the sur-ron powertrain/motor originally not very efficient .. middle engine with reduction. A DD hub engine is running much more economically, I thought. on normal use my sur-ron nucular 12f is also 28Wh/km. Stock sur-ron battery is in real life on a 90A controller more like 1750Wh, cells do...
