China has very developed bicycle infrastructure and massive public transportation compared to almost anywhere else. There are fewer car owners per capita than other countries. It’s still a smart play to use the hand of state to take steps to allocate the more energy dense batteries to applications that require them.
As I said before: Maybe these better chemistries that will replace lithium are just around the corner. I certainly don’t count unhatched chickens.
What do you want to know how to do?
I have. It sucks but it’s possible and because I live in a mountainous area I avoid that problem by using less assist so everything lasts longer.
The broader point I was trying to make is that If you’re trying to allocate the limited raw materials to the types of transport that benefit people the most then pushing e-bikes to lead acid makes a lot of sense. Yeah, the bikes could benefit from a more power dense battery, but they have backup pedals and ultimately their rider is the majority of the loaded bikes weight.
Electric cars and trucks weigh at least ten times what a person does and are generally used for longer distances than e-bikes so it makes more sense to use very energy dense batteries in them.
Again, I’m speaking from a position that recognizes the proliferation of electric vehicles in China and recognizes that the raw materials used to make lithium batteries are finite and in high demand, not from the position of trying to optimize the e-bike.
Hey, in a different egg thread I wrote a long comment about why eggs matter. You can read it here.
It’s hard to get people to grasp the meaning of inflation, and even if a person has partial understanding it’s easy to obfuscate it with other measures, but the meaning of expensive eggs is clear to everyone.
I meant the ~300 mile ranges common in electric cars. That’s a long trip. Plus if the car rolls to a stop by the side of the road you just gotta have it towed or charge it up in the field somehow, electric bikes have pedals.
It sucks to pedal a heavy ass ebike but you can do it in a pinch to get where you need to go.
I’m a wet cell lead acid man myself.
There’s the monthly battery fluid level check to contend with but if you can make sure it doesn’t tip over too often or too long and you can bank on being able to get to civilization once every six or ten years then you’re in the low total cost of ownership ecosystem.
Of course, they’re not as good in the cold and if you screw up and let all the water leak out then you gotta fill it back up and hope it’s not too messed up.
Whatever you pick will be fine. Tbh if you’re not gonna have the trailer for longer than the life of the battery, pick the one that’s got more curb appeal or resale value!
They make little ones for stuff like motorcycles and tractors. Just make sure it’s 12v, because atv batteries are 6v I think.
The safety thing is 100% true but only part of the picture.
E-bikes don’t need maximum energy density because they’re not gonna be used for long trips and are significantly lighter than cars and trucks.
China has many, many more electric vehicles than any other country and a ton of electricity production to run them. At some point it’s gonna become important to save the lithium batteries for the stuff that needs that high density power.

There are some possibly inaccurate and definitely confusing statements in the reply you got, but the first part, that agm is a physical structure of the lead acid battery that can be tipped over without making a giant mess and that deep cycle is another function of design as opposed to a function of the lead acid chemistry is correct.
What’s left unsaid is that lead acid batteries which are damaged and not working right anymore have a much safer and lower tech recycling process than lithium ones do and that’s saying something because one of the parts is lead!
Car battery works.
None of them are grammatically correct because none of them are complete thoughts let alone sentences.
All three try to specify the particular monkey by enumerating that it can see your ears but do no more.
Take away the description of the monkeys ability to see your ears and what you’re left with is “the monkey”.
“The monkey” isn’t a sentence.
If you are the subject and what’s happening is that you’re wondering if the monkey can see your ears then the sentence you want is “I’m wondering if the monkey can see my ears.”
If, as I suspect, you’re using “the monkey whose ability to see my ears I’m wondering about” as the subject of some larger more complex and cool sentence then you gotta lay out that part before someone can give solid grammatical advice.
No worries, I didn’t see that you were looking for open source or anything.
Are you mostly worried about the compromised American cell (and by implication other nations 👀) network or something else?
