Batteries have been the weak link in the solar renewable chain for some time. Claims, particularly by US companies are frequently rather wishful rather than actual, but batteries are improving a great deal and relatively fast.

Battery claims
The following link is to the complete list of claims I have been compiling.

https://martindavidwalker.blogspot.com/2024/09/battery-claims.html

The new claims in the last week are as follows.
April 19th 2025, Nakai university achieve safer high energy density 18650 batteries
In a process claimed to be compatible with existing manufacturing, they say they have achieved between 250 - 283wh/kg in a virtually non inflammable lithium metal battery.
The batteries also claim a long life cycle.

April 18th 2025, General Motors battery production overtakes Tesla
GM is going all in on batteries in partnership with LG, though reported costs are still in excess of $100 kwh, I have seen much lower Chinese costs. It really begs the question what does that cost really mean? These are massive investments and as such there's a big difference between the true cost and the so called marginal cost of each cell coming off a production line.
There's some talk about the next stage being space and weight saving prismatic batteries, but perhaps a takeaway is that in house production of any reasonably competitive battery is probably good enough.

Not looking particularly long range, but a small startup is finally advertising an EV truck that makes sense to me. $25,000 base model. Similar to model T, you can get it in any color, as long as it's gray. US rebate incentive would knock $7.5 off of that price if it can survive Trump Not sure how much more, but there will apparently be a range extender add on battery available

not a truck , a panel van

all electric ford transit, good enough for dhl round here, multiple body configurations, clean quiet and dhl will have done the maths on ev vs fossil

old transits were, or could be made, quite off road depending on type

the old low cc ones were better with a "used" but powerful sierra engine dropped in the hole(they fitted easily), better torque for heavy loads in traffic and 30% lower fuel use for oozingly gently driven long runs

this one is a bit silly but the pickup bit is rather good

i recon battery and motor upgrades are probably wise for a work vehicle or rough riding through the boonies for leisure and getting home again

Presume you mean the 2.3 Peugeot engine in the Sierra,economical and a good work horse.

i lost track of rat rod details ages ago one my chum used might have been a cossy upgrade, it did have fancy bits around the lump that one was a bit daft 2.3 pug seems reasonable for day van
