Sounds like some smart investors would do well to buy up the available lithium. With the dollar coming down like it is, having cash is a losing bet. How much...
Green economist Ken Stokes believes his platform of "greener, sooner, cheaper" is what Kauai Island Utility Cooperative members want, and he's hoping it's...
... randy, my first response would be that you never make fair comparisons so why start now? following that, where did you get the impression you can only ...
It's a 200W Motor to start with which may be enough on flat terrain ? Must be Gel type Lead Acid batts. I think they might have meant "regen" but that's not...
I am wrong. You can - but with Lead Acid you have to use bigger batteries to handle regen. It's much easier to accommodate in a Lithium configuration. Don ...
regen is a good idea for electric cars where the battery can easily absorb the short high current charge from braking events, but in ebikes it almost always...
So what percent of nickel is mixed with the zinc in Evercel batteries? ... lower than the all time high of around 52,000 usd struck last month. Prices are at a...
Nope UR wrong again, anything even a 7Ah is fine for regen. Crystalyte & Wilderness Energy Brushless motors achieve Regen by having the rider pedal like they...
... feat ... but also ... Evercels were ... ah ... of over ... pedal ... comparisons so ... Give me a good price for two 48 volt 12 ah packs to set a new...
... rego is Australian slang for registration as in annual car licensing fee. Jell is something you rub into your hair..... I can't imagine anyone actually...
Screw that, we need a Snow Thrower with tractor chains. I'm waiting for weatherman to say: I'm sorry but Summer has been cancelled via Global Warming, it will...
... personally i could not care less about the world record for climbing your volcano. what matters is whether an ebike power system can fulfill the daily...
How would anyone know other than Evercell? You have to ask them since they don't even make the batteries you are talking about available anymore. Don ... ...
I'm drawing a blank on who to ask, so figured I'd toss this out and see if anyone has a good guess. Have a chap in sunny Southern California who wants to power...
a solar panel producing 17A @ 48v or over 800W is virtually capable of powering an ebike directly. there are however a lot of losses involved in putting the...
But in this case no Batteries are involved. If he had batteries I would not be here asking. It is the PV Panel to the Controller to the motor. I would think a...
I think I would go with the bigger controller. That guy is going to end up putting batteries on that sooner or later and you will save him a little money...
the controller only needs to be able to handle the power from the source to the motor, so if you had a 17A 48v panel for an ebike you would need a 17A...
Same here, my first thought was, well maybe with ultra-capacitors - but then again who knows anything about ultra-capacitors ? Batteries are the only way to...
Joshua, From what I understand, solar panels need a load on them at all times (except in the dark), otherwise they overheat and burn out. This kind of mandates...
... this is not the case with any solar cells in my experience. the cells do not age more quickly when not under load. the major issue in most cases is that...
Bob, Thanks for the clarification. I have a old bus converted to a campervan, to which I had 2 x 80W panels fitted, and the supplier/installer told me that ...
One dealer here got 2. One sold, but the other one did not sell, so the dealer said "that is it- NO MORE!" That Xebra looks very useful for hauling my...
Even if you had 4 12 volt 4 amp Seamans pannels you would need a battery to stay running when a cloud moves across the sun.Pannels like this would weigh 80...
