If you know how, it can be replace.

Otherwise get a new 1. It can't be use anymore.

i ald watched the teardown, only problem is i cant weld the new batteries back after i replace them

i saw cheaper ones,

rm75 for 1.5ah
rm185 for 3ah

if newbie just buy completed unit.
diy you need to know the discharge rate. else will overheat and kaboom

You need battery flux to be able the solder to stick.

The core of the batt is 18650 cells.

If you know how to solder them, yes.

I bought refurbished WORX Li-ion batts. That's what the seller did.

Can. Just a regular 18650 inside. U can solder but not too long.

i know, just worried, normal solder cant stick

Been solder 1k+ of 18650 cells.

I use 110W solder iron and most important is the flux. Flux for battery is the most easy to stick.

maybe ill buy few batteries to test, may i know what batteries are you using?

Depend the original battery spec.

I use spot welder made from supercaps.

can be replaced, but some legwork required to get the inside cells. If lazy then 1.5Ah one quite cheap if seldom use. If use everyday then can invest in procore type

I want to get 1.

But think again, it just for battery weld. After that, no use anymore. Feel like waste.

So get solder better lor.

The supercap based spot welder costs less than rm100 so buy one to play around.


My battery are usually using screw type connection but maybe in future i gonna try making a portable solar generator.

My portable solar generator project abandon.

All parts here. Waiting to start back later. Using 18650@12v.

Another reason why I didn't use the welder is because I solder a fuse on the battery. The thin wire hard to weld.

18650 cells better use the fuse wire for more safety.
