Freedom Battery (Battery only)

Works great. I have two, hooked together, and have used them several times this year with California’s power outages and also camping. I’m glad I bought them and would buy them again.

This battery is far lighter than past batteries and lasts way longer.

Lithium ion batteries are excellent for holding the voltage to nearly the capacity of the battery which for this battery is from 9-11%. I use the battery mainly for backpacking with a cpap unfortunately my pressure requirement is 13 well beyond the design of 10 for this battery. So for a 7 hour night it uses 55% of a fully charged battery a little more or less depending on the night time temp. That leaves me with me only one night so I got a second battery. Now I have two nights and two partially charged batteries. The dual cord allows the use of two in parallel and I get a third night at the cost of carrying 3.4 pounds of battery. Note that when using two together the battery shuts down when the first one reaches its power limit leaving a higher charge on the remaining battery which can only be used it the low battery is disconnected. Okay I get three nights. The lifetime of the battery is about 400 complete discharges and quite a bit longer if not discharged to below 20%. Special cables are required so buy the kit and even more required for certain models of cpap. A great product requiring a good deal of user savvy as you can tell by now.

Used on a remote river trip. Worked great. Gave me about 12 of hours cpap operation. Nice display tells you % charge left.

I really wish I did not have to dig through the internet to finally find the last question in a FAQ that explained that these can NOT be used with the older C-100 also made by BPS. The older version are black, not white and have LED's instead of a LCD. But, the shape, size, specifications, and connectors are exactly the same.All I wanted was a second battery to get another night when sleeping. This would not work for that.

works well for my cpap

Horrible experience. These batteries take hours to recharge and only last 6 hours!

If you are looking for a company with integrity, do not work with these guys. They aren't willing to accept a return after 40 days. The manufacturer referred us to a different company to work with and we will be replacing the battery and necessary accessories with them. Don't expect good service here.
