Integrated BMS and safety switch

The SuperPack batteries are extremely easy to install needing no additional components. The internal switch will disconnect the battery in case of over discharge over charge or high temperature.

Abuse proof

A lead-acid battery will fail prematurely due to sulfation:

  • If it operates in deficit mode during long periods of time (i.e. if the battery is rarely or never at all fully charged).
  • If it is left partially charged or worse fully discharged.

A Lithium-Ion battery does not need to be fully charged. Service life even slightly improves in case of partial charge instead of a full charge. This is a major advantage of Li-ion compared to lead-acid. The SuperPack batteries will cut-off the charge or discharge current when the maximum ratings are exceeded.

Efficient

In several applications (especially off-grid solar) energy efficiency can be of crucial importance. The round-trip energy efficiency (discharge from 100% to 0% and back to 100% charged) of the average lead-acid battery is 80%. The round-trip energy efficiency of a Li-ion battery is 92%.

The charge process of lead-acid batteries becomes particularly inefficient when the 80% state of charge has been reached resulting in efficiencies of 50% or even less in solar systems where several days of reserve energy are required (battery operating in 70% to 100% charged state).

In contrast a Li-ion battery will still achieve 90% efficiency even under shallow discharge conditions.

Can be connected in parallel

The batteries can be connected in parallel. Series connection is not allowed. Use in upright position only.

Cool enough
Size: Queen, Color: White, Size: Queen, Color: White
I thought I had purchased pillows so when I received these I was a little disappointed. However that was 100% on me for not reading the listing and just trusting my search. I decided to give them a try and so far they seem ok. They don’t stay cool even though I have them on cooling pillows. They are super thin but very soft. They fit on my pillows perfectly. I don’t think it has improved my sleep quality but it hasn’t made it any worse either. I don’t think they are waterproof but I don’t really want to test that. I like that the zipper is small and seems to be decent quality. Smelled heavily of chemicals when I first took it out of the package but that disappeared after a few minutes.

Awful, very soft not firm at all
Color: White, Size: Standard/Queen, Color: White, Size: Standard/Queen
Ordered the Serta Ocean Breeze Breathable Medium/Firm Bed Pillow. The listing is misleading—it shows two pillows in the photo, but only one is included for the $47.00 price. The pillow arrived vacuum-packed and was extremely flat. Despite efforts, I couldn't fluff it back to a usable thickness; the total loft was only about 4 inches. Very disappointed with the quality and presentation. Returned item.
