I bought some new 18650 batteries (Epoch 25P) from 18650batterystore.com. A few of them were below 3v, but one was 2.45v. When I first put it in my charger (MiBoxer C4) it showed 0% charge, but did eventually charge fully. Is there anything I'd should be concerned about, or is this low state...

Hi Thanks for the post, but it was only two LiFePO4 batteries that I experimented with. Done, because the solar lights designed for lithium ion batteries, in a full day of direct sun only charged the LiFePO4 to just above their nominal voltage (3.25v -not overcharged) -I repeated this result for...

I got the LiFePO4 batteries and have been doing some testing. Charging the two batteries (Lithium Ion and LiFePO4) in identical lithium Ion solar lights, in full sun all day with me rotating them for most sun, the lights getting around 8hrs of charging sun (something they'll never see just...

Thanks for the reply, Substrate.

These are the solar lights. https://litom.com/collections/solar-wall-lights/products/litom-original-solar-lights-outdoor-3-optional-modes-wireless-motion-sensor-light-with-270-wide-angle-ip65-waterproof-easy-to-install-security-lights-for-front-door-yard-garage-deck

I have a bunch of cheap ebay solar LED lights with li-ion 18650 batteries. If I replaced the 3.7v li-ion batteries with 3.2v LiFePO4 18650 batteries, would it work just the same? Would the solar panels and circuitry that are designed to charge 3.7v batteries overcharge the 3.2v li-ion...
