    Replace or these still good?

    ??.. what else did you think it could be,…have you even tried to see if it acts as a brake ? Other than on a Road race bike, or BMX, i cannot imagine riding with a rigid fork these days, and that one does not look any better than cheap Walmart kit. I hope you are not intending to motorise that...

    Inside a Dual voltage power tool pack !

    54/18v , DeWalt ..9Ah see first photo . Also.. i dont see any smoke or flames ?.. maybe this is the safe way to “kill” lithium packs ?🤔👍😱

    Inside a Dual voltage power tool pack !

    Ever wondered what therse packs look like internally ? …or wondered what a water jet cutter can do to one ?

    Bobcat Lawn Mower (project in progress)

    “Commercial use”.. suggests a lot of use ?. you are using <5.0 kWh of battery on a 10+ kW motor, …but even if you only use 5kWh on average,….you can expect short working days ! what are you planing to recharge with ( charging time ??) In my experience, most of the noise from this type of...

    Anyone have experience with LiFePo4 scooter batteries?

    😱…”the authority” ? …🤔 ..controversial comment ! Did you learn that from BU ?.. They do not charge faster,.. they are also bigger and heavier than Lithium NMC /NCA etc ..Also , it has been around for 30 yrs !

    Does this imaginary voltmeter that I want exist?

    ????..your preference i guess,….but it seems like you will just be making your life hard for an inferior result ! An electronic device could present the info in so many different ways, as well as storing the data for later analysis.

    Thread for new battery breakthrough PR releases

    Now for something completly different !….. Grid scale storage, currently the domain of lithium batteries, Pumped Hydro, Flow cells , Thermal storage, etc ……may have a new competitor. And the core material may be a shock ! COMPRESSED CO2 ! Based on the principle that CO2 can be compressed to...

    Does this imaginary voltmeter that I want exist?

    Well technically that is not true. the needle is just reacting to a electrical signal, and as a mechanical device it cannot be faster than that input signal,… ….but a digital display can effectively be as fast as the signal. However,..what you probably mean is you find a needle display easier...

    Toyota’s 1:6:90 rule ?

    Small battery (<30 kWh) EVs would easily work for most of the City/suburban users (80% of australians ?) whose average daily usage is less than 50 km. Indeed some of the first EVs were just that (Nissan Leaf, 24kWh, 100+km) and were widely accepted, ….but as users tried to venture beyond the...

    Toyota’s 1:6:90 rule ?

    i guess that depends on how you view the data … …it appears to be a fast growing market sector !

    Toyota’s 1:6:90 rule ?

    EVs with small batteries (<20kWh) ..sounds very much like most PHEVs. with a useable electric range of 50-100+ km, they can easily fulfil the average car users daily requirement without using any fuel….…..and also perform the longer distance duties when needed. Edit… Australia alone has 47...

    Li-ion retirement?

    Before spliting the packs,..try “manual” ballancing of the groups by boosting the low voltage groups up to match the higher voltage groups, using a single cell charger. ( or drop the higher voltage cells back to match the others) Then cycle them a few times to see if they still lose balance. it...

    Toyota’s 1:6:90 rule ?

    Which is better than 1 EV releasing “0” CO2 ..TOGETHER with 89 ICEs each releasing 5+ tons per year !!

    Toyota’s 1:6:90 rule ?

    Thats idealistic, ..but this is the real world, and we have to be REALISTIC.! So any option that reduces the use of oil has to be considered useful. The whole world is not going to switch to EVs, ….but if many more can switch to Hybrids /PHEVs (or LPG) , then that is a big step in the right...
