.if so, why is it that every country that has significantly introduced wind and solar as a primary generation source, have seen their RETAIL. COST of electricity increase in line with the % of RE ? EG:- Germany, UK, Australia,….and in the US ,..California ! Understand the difference between...

..true but,… be aware, 80% limit (12.5v) will significantly reduce your driving time/range….. and remember because they are in series (12 x 5) , you need to check the voltage of each battery individually to be sure one or more of them do not go out of ballance.

??.. 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...

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 ?🤔👍😱

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

“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...

😱…”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 !

????..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.

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...

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...

Brand .? Capacity ? Voltage ? Link ?

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...

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

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...

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...
