OK - YOU do need a BMS!
After getting frustrated at you're failing to listen to nearly omnipresent recommendations, nearly everyone insisted that you needed to use a BMS ... years ago! But you stubbornly and consistently rejected the idea!
It honestly does seem that it takes a year or more of recommendations ≫ insistence ≫ badgering to get anything to soak into your head.
Just look back at all the failures, cost and heartache that you could have avoided by listening sooner?
Yea. I guess it started to really soak in when I realized that it wont be much more difficult to wire up a BMS than the balance plug I used to charge up the 6S packs. The BMS being much easier and simpler and allow for charge anywhere just plug and play , no power supply to haul around. Also owning and using the SONA packs I got to see how the BMS works first hand.
The most expensive failure and heartache was the cheap crappy LiPo packs I got off of e bay. The fact that the old LiPo packs Dan sent me is proof that it was not really my fault that the e bay LiPo failed as the old packs still run. However I will accept the responsibility for not listening and buying them in the first place. I was warned and did not listen.
I spent about as much on the LiPos that failed as I did these fake LG cells but most of the LG cells I can still use and am building two 10S packs. I wish I could say the same about the LiPos. I have two 8S LiPo packs with one bad cell in each and two 10S LiPo packs also with a bad cell in each. They could be converted into four 5S packs but I am scared to take them apart. Only one of the cells is puffed up.The other 3 packs have one cell that is unstable.
Also if DA was to have built and sent me a large 18650 pack and I sent him some cash for his trouble I might have avoided the e bay LiPo but I would have simply ran them and would not have learned anything. Now by building my own lithium packs I am learning an important skill. there are two different types of people who ride electric bikes and vehicles for that matter.
1. Type one is strictly an e bike / vehicle operator. This type of person does not want to get their hands dirty or try anything new. They will spend $1,000 , $2,000 or more on an e bike straight from the factory. When the battery pack fails they will spend $500 : $1,000 or more to replace and when something else fails about the same to repair or replace.
2. My type who has an active e bike workshop , experiments with chain drives even though I own three hub motors and I build my own batteries now my way and do not give up until it works. I enjoy getting my hands dirty simply to get some satisfaction.
Is all the heartache worthwhile ?????????????
DAMM RIGHT ! Every time I ride what all you used to consider my death traps but now since Doug is here you all can see most of them have pedal chains and good working brakes. It is all worth it to me every time someone stops me and says "Hey. Did you build that yourself" " Man that is really cool " " Could you build me one like that" " How much would you sell that for"
My response is I got the motor off of e bay. I will ask them if they are mechanically inclined. Then if they never worked on go carts or motor bikes I tell them that a hub motor kit from e bay is simple and easy to install. Also less than $200. Now I tell them a geared hub motor is better as no drag and easy to pedal. Thanks for posting and your patience.
I build e bikes. There not always pretty or practical but sometimes they work, at least for awhile. Immortality is not a dream but the future of our evolution. We were given the tools to forge our own destiny. We were created in gods image and shall evolve to live forever.
