In this video I’ll show you how to double your cordless power tool battery capacity by changing old 18650 cells with new Sony VTC6 cells and spot weld them with my new Arduino spot welder.
Arduino spot welder I got from www.malectrics.eu

This battery reconditioning program exceeded my presumptions. It worked on any drill battery, several AA and AAA batteries batery.repair and any camera battery. The steps are simple and the act itself is exciting to do. No matter what type of battery you`ve got, it is sure to function again!

CAUSE THERE IS NO CONTROL CIRCUIT BOARD AND YOU CAN EASILY OPEN HOLES ON THE NICKEL PLATES...!!THERE IS ALSO A 300A FUSE ON THIS PARTICULAR ARDUINO UNIT YOU USE...!! also if you add the 90 dollars and the 60 of a 500cca battery you are almost near as here www.ebay.com/itm/788H-Battery-Pulse-Spot-Welder-18650-Battery-Charger-Tester-0-1-0-2-mm-220V/122733520271?hash=item1c937ce58f:g:XVcAAOSwAVxZ0KK6 which without any mosfet mod you go up to 800amps and 0.2 thickness and you dont mess with arduino complexity ...anyway...it looks like a very well built ,reliable AND MOST OF ALL COMPACT unit!!

ps.. amps and miliamps are the same thing just a different measurement.. and 18650's might have 7 amps of life.. and what he's done is limited that motor to below the recommended voltage.. = less torque.. amps or volts.. cant have both.. essesially the drill will use twice the amps to spin the motor giving him no extra work time either hehe

@xdeadwrongxdeadwrong7181 5 жыл бұрын

@@harleyme3163 not sure...so he ordered battery's with a larger capacity...so basically holds a bigger charge ..didnt change any specs of the drill itself expect for the charge range...which is now longer than the stock version of it's original design.

@Rendus4 5 жыл бұрын

Soldering the cells does physical damage to the cells, but the general concensus is that the cells do not lose capacity or life cycles as long as the soldering heat was only applied for a few seconds, so be sure to use a 200 watt+ soldering iron and not the typical 30 or 60 watt ones.

@kimt6333 5 жыл бұрын

A fully charged 18V Li-Ion battery is at 21V, and a fully discharged battery is at 15V, so any voltage between that is good, it's a matter of charge state.

@johnrhodes3350 5 жыл бұрын

The reading was as they are shipped or for long term storage roughly between 3.4V to 3.8V Long Storage at Full capacity can damage them and is unnecessarily dangerous, due to high energy density. It's a risk of fire or explosion if short circuited or otherwise damaged He was only looking to see if they were all roughly the same ie. Balanced If one was lower than the others it could indicate a faulty cell.

Hi! Is it possible to double capacity of Hilti cordless powertool like drill 22v 3.3Ah?

@pr0xZen 4 жыл бұрын

Maybe. Check inside, how its assembled and what cells are in it, ot will tell you whether there's really any gains to be had, and if it's feasible to do the job (this battery pack was frankly on the easy end of the scale to replace cells in, among modern power tool battery packs). But top shelf power tool manufacturers like Hilti rarely skimp on cell quality. Maximum capacity ain't everything though. Besides that and cost, ere's (sustained) discharge current, behavior in really cold or warm temperatures, long term capacity retention, lifetime charge cycles ratings etc. Can't have the best of everything in one cell, it's always a compromise. Some tool "system" manufacturers even offer special battery packs tuned for special needs, like arctic or super hot surroundings, and ofc the more typical high-demand (high discharge current) ones for super torque'y tools like hole hawgs, big impact wrenches, sawzalls, concrete hammers etc.

There is a reason why power tool batteries have cells of such small capacities that go without protection circuits. They are simply much more robust and more difficult to explode than high capacity cells that push it to the limits and NEED protection circuits.

@harleyme3163 5 жыл бұрын

nothing to do with protection.. you know its only the voltage thats matter since they only draw the amperage that they require to function.. and if you think there's some special anti battery exploder.. most charging circiuts stop charging when its gets feedback (battery full and charge is coming back since battery isnt taking it.. you cannot overcharge a battery if you use a proper charger.. they are meant for specific amp bat's there for specific VOLTAGE..just takes longer to charge a bat with higher capacity

@mibars 5 жыл бұрын

@@harleyme3163 No! These Lithium cells are not self-balancing, like Nickel ones! You can have e.g. 6S1P battery with a total full charge voltage of 25,2V, but it doesn't mean that all cells will be 4.2V. It takes just one cell with slightly different internal resistance or lower capacity to throw the pack out of ballance, e.g. you will have five cells at 4.15V and one overcharged at 4.45V.
