I am looking to make one of these lipo chargers.
planning on ordering parts this week. Anyone else interested in making it? we can make a SMD party out of it.
@TomKeddie is supplying me the PCB, he’s got 5-10 at $1 each
I’ll do one.

Also in! Thanks Mimi.
i am going to take a looke at what SMD we have at VHS.
and order what we need accordingly. probably looking at 5 kits atm
Cool! I’m in for one too!
Let me know what components we need and I can help you find them. We have an excellent inventory of SMD resistors in the filing cabinets at the space. We also have tons of SMD caps but they are a little more difficult to find. I have some SMD LEDs I can donate.

RT1 1K R0805
RT2 150K R0805
U1 MCP73833T-AMI/MF DFN10_3X3MM
by the look of it all smd passives and leds are 0805. the caps are pretty generic. and i mostly have to order the MCP73833 IC
i also need to check if we have jst, microusb, and dc connectors
Count me in too. Even though I just built a charger from salvaged parts.
I’ve been wanting to make a few of those for a while. If there is enough interest, could we get a run of the boards as well? I could go in for at least 5 kits myself, maybe more of the boards.
I am interested, if there are any boards left
I would suggest skipping the JST connectors, they’re over a buck each on Digikey/Mouser. I just soldered an 18650 holder to it.
I’m about to send a pcb run to pcbway.com - is $US12 for a run inc shipping, I think we might be able to get 40 boards from that (4x4x10). Shipping is epacket so would be a fairly reliable 30 days.
Should have been clearer- I’m sending a run for myself, if someone want to pay the $US12, I’ll add 40 lipo chargers boards to the order (the 40 is a maybe, the 10 is for sure).
I have a bunch of 3S RC charging gear but nothing for 18650B’s. I’m in for the parts; if I can make it work with my vacation plans I’ll join the party.
Let me check my stash; I should have enough JST connectors to donate to the cause. Will confirm
Hi,
I would like to join the LiPo build and request one PCB.
Thanks,
RK
Depends on the price. I’ll be getting the 40 boards so don’t count me against the 10-board limit, and in fact I’d be willing to throw some of my boards in at the $1 each if we go through all of his and we are waiting for the delivery.
If I still have them, the ones I have are on leads.
So, on the issue of the connector.
What is everyone planning on charding with their charger. JST ph2 connectors are a pain in the ass if you don’t already have mating ones and I am not sure if everyone needs that connector
JST is what i usually use since my batteries tend to be either adafruit or knockoffs of theirs
