Constant Current Power Supply - 12.6V 10A
A simple constant current power supply that outputs 12.6VDC and 10A. It comes in a robust metal enclosure (IP68 rated) with a 100,000 hour service life. It features Over-voltage, Over-current, Short Circuit, and Over-temperature safety features. This can be used for charging Li-Ion batteries similar to the one we sell but requires good knowledge of how to do so. It also works for powering LED lighting-type devices.
\The device accepts 8-36V DC inputs via 14 AWG wires (The Red and Black ones) and outputs 12.6VDC and a constant 10A for current via the 16AWG wires (Yellow and Black).

Constant Current Power Supply - 12.6V 10A Product Help and Resources
Core Skill: Soldering
This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

Core Skill: Electrical Prototyping
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

This is NOT a battery charger. It is a constant current power supply that can be used to charge (some) LiIon batteries.
However, it has no provision for a battery management system or cell balancing, so if your LiIon battery pack becomes unbalanced (one cell has higher or lower capacity and/or state of charge than the others) it will risk overcharging one (or more) cells, possibly leading to a fire.
It is dangerous to label it as a "battery charger" when extra components (BMS) are needed to safely charge LiIon batteries.
Thank you for the heads up and you are correct. It was a misunderstanding on my part and some holiday brain fog. Fixed the description and name.
I agree. Isn't this just a DC-DC converter that would do a good job replacing a 12V battery? I've used these on airborne platforms to drop the batt voltage down to 12V and they source current well. But I agree with what you said it has no BMS and just spits out voltage. Sparkfun, are we missing something?
I'm confused. How can it output a fixed 12.6 V AND a fixed 10 A. I could see a fixed 10 A at up to 12.6 V or a fixed 12.6 V at up to 10 A, but not both. To have both you would need a dynamic load that regulated its consumption to 126 W.
Agree, it is not possible to have constant current and voltage output in general. I think that what the datasheet means is that the output voltage is constant at 12.6V up to 10A continuous current (i.e. maybe some spikes higher current are possible). Would be great to have confirmation from SF after some testing :) .
