Bosch Blue 18V Lithium-ion Battery full repack instructions - (10 cell) 

Glad the video helped!

I myself replace all cells but if someone want a me to do 1 cell (and provides it), I'll do that.

I've never compared single and double packs but I know that using doubled strips will reduce the heat when using the pack on high draw tools.

Yes it's possible to fit cells with a higher ah rating.

Two layers of 0.12 or 0.15.to make a total of 0.24 or 0.30mm.

10 cells will be 2 rows of 5 cells. Using 3000mah cells will give you a capacity of 6ah (6000mah).

@@spinnanz great! Thank you.

Samsung 30q.

I'd 1st check the button, that can become faulty with time.

You are correct. They are LG chem cells, lg18650mh1.

@@spinnanz these are not cells for electrical machines. You will blow them out very quickly.You need high drein cell more then 15A discharge

@@kocetoMR this video is an instruction to replapce the cells only. I recommend using 20a related cells.

@@spinnanz What you say doesn't make sense also it's misleading. So you show how to fix a battery pack by using wrong cells BUT this video is what??

@@billadmond9450 I make no recomndation in the video to use these particular cells, nor do I even say that they are. At 8:10 it clearly states the specs of the original cells and the video description has the brand and model of the original cells in the pack.

@@qt1qg do you have the battery model number?

@@spinnanz I don't have a model number, but name in the online store is ProCORE18V 8.0Ah Professional. I just want to know if I am going to be perpetually scammed in buying overpriced batteries if I buy new Bosch products.

@@spinnanz I don't have a model number, but it is called ProCORE18V 8.0Ah Professional. I just want to know whether or not i will be reliant on overpriced batteries if I buy new Bosch products.

@@qt1qg I'm not sure if they lock or not but I see there are aftermarket cases and bms available so if they lock, you'd just replace the BMS too.

@@spinnanz so the tool does not reject non-OEM BMS, or at least someone find a way around if it does. Thank you

In my country an 18v 5ah bosch pack will cost me $190 for a 5ah. 10x 30q cells will cost me $137, so I can make a 6ah pack. Thats a 27% saving and get a 20% larger battery.

@@spinnanz When you talk about numbers you need to be more specific but it's clear to me that you mention things like people chit chatting at the local market: what country you buy the battery from, what cells brands and where you buy them, how do you get 20% energy by using the same cell specification?

@@billadmond9450 I don't need to be specific at all. If you don't like the video go make a better one yourself. My example above is using 30q cells, which have 20% more capacity than factory.

I've had 2 Makita that were locked however when they became faulty (with the original cells inside) the owner tried at elast 3 times to get them to charge on the charger. I've heard this can cause the BMS to lock. A set of 4 after market BMS's are around $25 for the set. I have repacked working but worn out Makita with no problems. I couldn't show this Bosch charging as I don't have a Bosch charger however I waited until the owner confirmed with me that the battery had done a full charge/discharge before I posted the video up.

Hilti lock BMS after voltage drop… only what you can do is buy new one…
