I'm looking to replace the 6600 mAh battery with something that has a larger capacity. Would the following work with the SunAirPlus? www.tenergy.com/31059Regards, Kevin |

Kevin,
Looks good to me!
What is the price of that unit? If it is less than the Adafruit one, I'll start recommending it.

I purchased a JST-PH 2-pin cable ( www.adafruit.com/product/261) from Adafruit. According to the JST documentation, the connector can handle a 2A load. The Adafruit cable has 26 AWG wiring. My new battery comes with 20 AWG wiring. My plan is to solder the cable to the existing battery wires but I'm now concerned about the load capacity of 26 AWG wire. Note: The 6600 mAh Adafruit battery I'm currently using appears to have 24 AWG wire. Do you know if it is safe above configuration is safe to connect to the SunAirPlus? Thanks Kevin |

Kevin,
Good for you checking the wire limits!
I don't think there is any issue because you will never be taking more than about 1000mA from SunAirPlus on the land and that will be less than 2A current at the battery.

I should have been more clear with my question. I think the JST connector will be fine. My concern is the very thin 26 AWG wire attached to that connector. Can 26 AWG wire be used safely with the SunAirPlus?
I've seen as much 700 mA pushed into the 6600 mAH battery when charging on a very sunny day (as reported in the batteryCurrent column of the PowerSystem table in MySQL). Is 700 mA too much for a 26 AWG wire? The 6600 mAH battery has 24 (maybe 22) AWG wire.
Thanks,
Kevin

Texag,
Yes, it can be used safely with SunAirPlus. 26 AWG is still fine with 2000mA. You shouldn't exceed ~1700ma on a very bright day.
