Re: Nickel strip current question.

This is "Matador Amperecity Table" by "Matador" found in many places on ES. Thanks to him. It is self-explanatory, so just give it some times and your answer might be in there. Ampacity (Powestream extrapolation).jpg Should you need more detail, just ask, then someone will come h...

Re: Battery BMS or charger phone alert

I always want one of what you mention, even from afar that I wish to remotely charge/turn off the unit or monitor my pack. But never seen one. Let me know should you come across such a product. For the time being, I use a timer to set the duration I want to charge, for the very basic. Try it several...

Re: bluetooth BMS?

Further question : for the above BMS, what communication should I go for : a CAN or RS 485 ? and why ? It s a pity that the seller just do not know much about the products. Thanks in advance. BTW : I already ordered the above (from IC GOGOGO / Ali) JK-BD6A24S10P @ 100A/200A peak, 0.6A balancing curr...

Re: bluetooth BMS?

Thanks john61ct : I am just looking for a better than my previous BMS (bluetooh, 14s 60Amp from LLT). After about 2 yrs, I guess there must be some better or much better products out there. But not much to my finding. GPS tracking, like I asked, just try to figure from the seller whether it is for t...

Re: Nukeproof Mega - GMAC - Nucular 12F trail/enduro build

Five or so years ago I bought a run out special Nukeproof frame from ChainReactionCycles. At the time the appealing features of the Mega TR were the relatively large frame triangle for battery, removable dropouts that made for a easy conversion to steel plates for fitting a hub motor, all packaged ...

The Haro 357 NIne DH frame, that I had lying around for serveral years, seemed like a good match for the Tange...

Re: ++Giant Glory DH build + GMAC + PhaseRunner

I am another witness of MJ1 good story. After 11K km (in <2 yrs) and 250+charges or so, it is still going strong. But my usage is about 50% of pack capacity, with shallow cycle 3.6-4.1V and charge just hours before each rides most of the time. Actually, the my phone Xiaoxiang bluetooth app shows onl...

Re: ++Giant Glory DH build + GMAC + PhaseRunner

you could just get the gmac and get the bike running for his bday and if its too slow get a DD for him later. if youre going for regen, you might want a 40T pack. i tested the vtc6 and a 30Q with no wait times in between charge/discharge cycles and the vtc doubled its capacity loss/cycle and the 30...

Re: ++Giant Glory DH build + GMAC + PhaseRunner

You're talking 4, maybe 5 HP tops here. Sure, you may have 60 lb-ft of torque, but you can control that in the settings and increase the performance as he gets familiar with the bike. Too little power and he'll lose interest. Think of all the crap and dangerous stuff you did at that age. An ebike i...

Re: raising voltage to maximize regen. braking?

I would normally let this pass, but given your obvious interest in making sure we all know the pros & cons, I hope you won't mind. "Lithium ion" is actually generic term that includes all Lithium battery chemistries, including LiFePO4. They're all safe enough to be widely used, when u...

Re: raising voltage to maximize regen. braking?

. Just a thought : I am no expert and still learning. Just want to share some idea, so please bear with me : Enthusiasts here on ES are interested in regen braking regarding its motor's back-EMF vehicle stopping capability as an alternative but can be an effective primary brake. While energy re-capp...

Re: ++Giant Glory DH build + GMAC + PhaseRunner

BTW, my 1st build of 14S5P LG18650MJ1 : The BMS app on phone shows around 85 charges for the 10k+ km rides which is wayyy too less actual number of charging. I figure it should be x 3.5 that is about 300 cycles already. I feel the pack degrades a little, but not much. Charging time is a little longe...
