Idiot's guide to a self build battery

Haha, no I get it. And yes the info you guys have on this thread are awesome as is. I’ve already kicked off convos with both those suppliers for quotes, which I’m waiting for them to reply on. As you guys probably know it takes a while for them to respond.

I’m just posting the above to show why to the inexperienced should probably be cautious (myself included). Dangerous world out there

Cool, thanks for taking it well.
Best of fortune to you in the quotes. I know exactly how it feels when you're putting serious money out on an E contract. Colin Deng was 10/10 throughout the process, it was such a relief to find him.

FWIW, my experience with buying batteries and cells from China has been 100% positive. I bought lots of LiFePO4 cells from a company called Headway, many years ago, and was impressed with the efforts they went to make sure I was happy with the purchase. I believe the key is to gain confidence from corresponding with them and making sure you and the supplier are on the same page. My experience was that, in general, reputable Chinese suppliers seem to value the relationship with their customers, and will try and be as helpful as they can.

It's a shame that there is so much suspicion around Chinese suppliers, almost all of it a consequence of some scam artists that sell on Amazon and eBay, I think. Neither Amazon or eBay seem to be bothered by the plethora of dodgy resellers that use their sites, whereas I think Aliexpress tends to be a fair bit better, often because you're dealing directly with manufacturers or suppliers that need to maintain their reputation. Only downside is with payment protection, perhaps. Never had to use it for any Aliexpress purchase, but I have had to use it several times with eBay, and knowing you can get your money back if something goes awry is probably why eBay seems to be trusted a bit more.

I recently had to use the purchase protection on Aliexpress with some CCTV cameras I purchased and was give a full refund and didn't have to return them. Wasn't a problem at all.

A few years back I ordered a £5 volt meter for Aliexpress which did not turn up, the vendor just sent me another after 3 weeks and the replacement one turned up within just over a week. The original item then turned up about 6 months later which made me wonder where it got stuck.

It comes down to common sense like ebay, check the reviews and how many orders they have sold and is it too good to be true.

I have been fortunate enough to have been out cutting about both Shenzhen and Zhouhai. About a dozen years back. Excellent places, great people. I bought an outstanding carved wooden standing Buddha when.i was pissed. Had been into this shop a few times, unbelievable carvings in both wood and stone to scales I won't even try to describe. Mightily impressive. Anyway, paid for Buddha, gave the guy my address in Scotland then I jumped the ferry to HK and onward to home. Sure enough, 6 weeks later, Buddha rocked up at my house.

Wow thanks joe

Plenty of ways you have posted to get in touch with Colin .

In the mean time, kick started by buying a BMS on the 11.11 Ali sale -
It’s from their official store, and I see many battery videos using the same BMS so should be a good

Figured it was about the price of a balancing board and get the benefit of Bluetooth. Can’t say no to Bluetooth

Funnily enough, it was cheaper getting it shipped to the UK than getting it delivered to HK, for a relative who is coming back in the new year to carry over. Hah
