Onoff Posted December 9, 2016 Share Posted December 9, 2016 (edited) This just out if interest: Bought a BL1830 clone a while back at random on eBay. Can't fault it the. Charges, doesn't get hot and lasts. Decided to get another for a freebie BHP452 I've just been given (needed a £2 forward / reverse lever). As you do I thought I'd compare the guts side by side. Externally the case looks identical. Looks a bit different inside though. The old clone's on the left and the new one on the right: EDIT: Should have added that the latest clone on the right ( with the red cells) is from here: http://m.ebay.co.uk/sch/m.html?isRefine=true&_odkw=makita+18v&_ssn=lycfeng&_sop=15&hash=item25ad3101dd&item=161819460061&_osacat=0&_from=R40&_trksid=p2046732.m570.l1313.TR12.TRC2.A0.H0.Xmakita+18v+battery.TRS0&_nkw=makita+18v+battery&_sacat=0&_trksid=p2046732.m570.l1313.TR12.TRC2.A0.H0.Xmakita 18v battery.TRS0&_mwBanner=1 Bought on recommendation from a member here who rated them. Not used in anger yet so time will tell! It does look well made though with an attention to detail etc. I must compare to the inside of a genuine Makita BL1830. I've no doubt voided any warranty but for £22.99 I'm not overly bothered. I'll openly admit though that with these clones I NEVER leave them charging unattended.

Onoff Posted December 11, 2016 Author Share Posted December 11, 2016 (edited) Just bought a battery pcb to try and resurrect a genuine BL1830. http://www.ebay.co.uk/itm/4-5x3-3cm-18V-PCM-PCB-Lithium-Battery-Protect-Circuit-Module-Board-For-Makita-UK-/152190429598?hash=item236f41a99e:g:9dIAAOSwqfNXoBVv On eBay for around £6 from Hong Kong etc if you don't mind waiting. Will report back or you'll see the pictures of the fire in the paper! Edited December 11, 2016 by Onoff 1 Link to comment Share on other sites More sharing options...

Onoff Posted December 17, 2016 Author Share Posted December 17, 2016 (edited) A genuine Makita BL1830: The new board's reference: High temp solder used on the original terminals, I struggled with a 25W iron. Once desoldered it looks like this, still attached by this ribbon cable affair: Underside there's what is the temp sensor on the pcb stuck into the casing with white compound: The new boards temp sensor is on the top side of the pcb so won't embed into the case like the original. No instructions with the new board btw. Assuming I should ditch the ribbon cable as it only went to the old board. Again I'm guessing it goes something like this, reds together, black on it's own, white wired sensor stuffed down the front: The indent for the board screw is imo, slightly in the wrong place and puts the whole new board a bit off kilter. A bit of Googling on this methinks. Edited December 17, 2016 by Onoff Link to comment Share on other sites More sharing options...
ProDave Posted December 17, 2016 Share Posted December 17, 2016 TIP: the "high temperature solder" is lead free. Mostly just tin. I just reflow immediately with 60/40. that gets it melting easily with a low power iron. I have enough 60/40 to last me out, but TIP #2, CPC still sell 60/40 solder.

Yep, I just tinned the iron with a blob of 60/40 against the hard stuff and got there in the end. Link to comment Share on other sites More sharing options...

Onoff Posted December 18, 2016 Author Share Posted December 18, 2016 Was just finishing it when at 10.20 the phone rang. Had to go and sort a main switch in a cu for a friend. Link to comment Share on other sites More sharing options...
Onoff Posted December 18, 2016 Author Share Posted December 18, 2016 Giving up with this! The original pcb has various notches along its edges which the new one doesn't. The notches fit around "pegs". I've started to Dremel notches into the board but am exposing tiny copper tracks. The other option would have been to get rid of the pegs. But then I'd be worried about it locating properly. For another tenner I could have bought a clone I know works! Link to comment Share on other sites More sharing options...

Trw144 Posted December 29, 2016 Share Posted December 29, 2016 Any verdicts on the clone batteries? Just picked up a makita cordless circular saw without battery thinking I would use the battery of my makita drill. Just ripped the box open, went and got my drill to nab the battery, only to realise my drill is actually a Bosch! I see see some clones on amazon. Are they any good/safe?

Construction Channel Posted December 29, 2016 Share Posted December 29, 2016 I haven't had may issues so far, iv had a few break but the same can be said for genuine batteries, i recently bought 2x 5ahs and they seem fine, but only had them a week or 2 so can't really comment on them. for the price i would say they are well worth it, Link to comment Share on other sites More sharing options...
Trw144 Posted December 29, 2016 Share Posted December 29, 2016 Ok, just ordered two 4 ahms plus a charger for £70. My tools don't see a lot of action compared to you lot so hopefully it will do the job just fine. I m going to attempt to cut the bottoms off some ikea pax wardrobes so I can maximise the space and use the taller versions (my ceilings are about 5cm too low).

Have a word with this bloke.....I'm sure it could be done the other way around I've come across a few adapter ideas to use one make of battery on another and my first thought was that it's an ideal thing for 3D printing. Of course somebody has already done it. It's be great if you were way a Makita fan to "convert" all this old, off tools to use the Makita Li-ion battery.
