Can you tell me what the MAX input voltage is for the PowerBoost 1000C? I want to have my battery recharged by solar, but the panel might output 6V (or perhaps a bit more). I was going to use the Solar/LiPo Charger -> VERTER -> 5V USB, but if I can do it all with the PowerBoost 1000C that would be perfect. I may be answering my own question, but the spec sheet for the chip on the PowerBoost says Max input is 5.5v ... so...
So maybe just skip the Solar/Lipo charger, go with the Panel -> VERTER -> PowerBoost 1000C ... Or perhaps some way to limit the 6V from the panel to 5.5v and skip the VERTER all together. Any help would be great.
Thanks
Roy

Re: LiPo Solar charging with PowerBoost or ??
5.5v is the maximum recommended operating voltage, but the MCP73871 can survive supply voltages up to 7v.
It's best to leave some safety margin below the absolute maximum, but 6v should be okay. If you're concerned, put a 6v Zener diode on the solar panel's output to clip any peaks.
