Re: Rebuilding battery pack

I had similar problems dismantling Chevy Volt battery modules.
first rule is to wrap with el. tape other nearby tabs when you work on any given tab.
I cut upper section of 2-cell tab simply with sheet metal cutter and forced the tabs apart.

Re: Suspension Wheel with pneumatic-spokes!!! Checkit!!!

so with this you have 3 shock absorbers.
for the cost of those shocks you could buy very good quality front wheel fork,
no wonder the idea never was never implemented in MTB for example

Re: Motortrend article with tons of info about Tesla’s Cybertruck

EV versus fossil vehicle expenses over say 5 years.

how to check condition of battery?
run discharge test, of course you need equipment namely battery analizer or do it with light bulbs as a load.
you should be able to calculate Ah or Wh on discharge.

Re: Battery pack made from several small modem packs.

modem packs are used, right? not new?
I would check every pack for weak cells
of course leave pieces of tabs welded to cells maybe like 1cm for future soldering.
packs are used and recycled for the reason. there is always weak cell or two in such pack.

Are you sure those clamps would not move around once the pack is placed on ebike? I always use screws with alu tabs there are ways to prevent screws from going loose. how do you connect balancing wires to those clamps? - you have to drill them or cell terminals to attach balancing wires. right? with...

Re: Is there such a thing as a wattmeter/ammeter with a sound voltage alarm?

it is complete different animal than celllog, because it uses shunt.
I for myself use CA with shunt for watts, Ah, WHr calculation.
however CA do not have any alarms.
I would not connect in series unknown quality shunt .
CA is rock solid and individually calibrated, shunt I trust.

of course EV will survive without subsidies.

celllog which was excellent battery cell monitor with LVC and HVC alarms .
those alarms with open collector outputs could be configured to NC or NO /normally close/open/
as far as I know there is no equivalent device for hobby market right now.

Re: Lime Bike battery fire

I understand Limes have all installed GPS locators so company can find them, right?
now
when you push it on your property they are going o find it before battery dies.
Obviously GPS is powered from seperate battery.
