SparkFun will be closing early at 3:30 Friday 5/27 and remain closed Monday for Memorial Day (5/30). Orders placed after 2pm MT on Friday (5/27) will process and ship out on Tuesday (5/31).
Description: If you need to charge LiPo batteries, this simple charger will do just that, and do it fast! The SparkFun LiPo Charger Basic is stripped down of all features and just does one thing well - charge 3.7V LiPo cells at a rate of 500mA. It is designed to charge single-cell Li-Ion or Li-Polymer batteries. Check the datasheet below to see if it will work with your battery.
The board incorporates a charging circuit, status LED, connector for your battery (JST-type used in the batteries we carry), and a micro-USB connector. A small mounting hole allows this charger to be easily embedded into a project.
Note: This version uses a micro-USB cable. We also have this charger with a mini-USB connection as well.

I love this product ! I buy more and more. But sometimes I would like that the staff reply to the comments below the product .
and maybe make one with a cutoff circuit (like in the mac books !!! ) please .
When the power is connected battery charging and power via 5v usb, when the charger is unplugged battery takes the relay
Thanks for the feedback. I have passed this along to our engineer in charge of this product for consideration for revision. Thanks and happy hacking.

I’ve bought five of these and I have been having some trouble. It seems that they will charge for a few minutes and then stop or they will not charge altogether. I love how small it is and I am using it in a project, but perhaps the mini-usb version will be a bit sturdier and less finicky.
Just plug it in and it charges batteries, at a low cost and no trouble whatsoever.
These LiPo charger ‘basic’ modules are working fine for me, although I wish Sparkfun could include solder pads for Vin and GND so bypassing the USB connectors would be a bit easier. I had to parse through the schematic and view the board under magnification to figure out the +V and GND runs, and even then I screwed up two basics before I got it right.
I have a dual LiPo battery setup for one of my wall-following robots. A relay switches the batteries from a parallel configuration for powering my robot to a parallel configuration for charging. The on-board charge status LED is a nice touch, too.
On an earlier project I used the basic’s big brother with the 3.3-to-5V boost option, but realized I didn’t really need the boost feature, so went with the ‘basic’ for all subsequent work.
The product seems to work, but the LED on the charger doesn’t light up. It"s hard to know how long I should keep the LiPo plugged in for full charge.
Jest got through test charging the first battery (18650 2000mA), had to find out how the charge indicator worked, “ RED While charging, OFF when finished, makes a quick flash when plugged in to the USB and no battery load”. Wish I could get the mating connector with Red & Black pigtails for battery but did not find them on the web site as separate Items.
its small size makes this a very versatile charger. For example, I was able to insert this in 5/8" tubing for a LED hula hoop that had a broken external wall charger. I saved 30 bucks from ordering a charger from the hoop manufacturer, and now the hoop can be charged via USB! no more worries about carrying around the correct charger. My only complaint is I wish it was a wee bit cheaper!
I’d like to imbed this, but I’m not even going to try to take that USB connector off or solder a wire in there. [I'l probably buy a bare Micro USB plug and use that.]
because they do exactly what they’re supposed to (charge the lips batteries I use in wearables), they’re small, and thus can be carried in quantity to Maker Faires, and keep my electronic wearables batteries happy and powered. They’re also faster than anything else I’ve tried, without making me afraid something will catch fire.
Truly plug and play… that is plug to your computer and go somewhere else and play.. cause your battery no longer needs you around…
