Which batteries use Seiko protection circuits? -making list

Hello guys.

I know a lot of the high quality batteries use protection circuits from Seiko and that this is supposed to be the gold standard.
What I’d like to do is to make a list of which battery brands use the Seiko protection in their batteries. If this doesn’t already exist that is… In that case, please point me to a source :slight_smile:

I would very much like your help in adding known batteries/brands to the list!

I’ll start the list myself:
Keeppower.

[edit: Please give me a shout if you observe mistakes on the list, or have additional information, like if for example a brand uses seiko in some models and other circuits in other models]

THE LIST :slight_smile: -to be treated as work in progress, and not absolute truths…

-

Batteries/brands that have been confirmed to contain Seiko circuitry

  1. Keeppower
  2. Evva

Batteries/brands that are believed to use Seiko circuitry
1.
2.
3. Orbtronic
4. Armytek
5. PluzPower
6. Nitecore
7. Skilhunt
8. Redilast
9.

Orbtronic

Armytek

PluzPower for you brits

Nitecore

Skilhunt

Orbtronic Armytek PluzPower Nitecore and Skilhunt added.

How about the Xtar batteries? Seeing a few references to them having Seiko IC’s? Is that correct?

Claim to use? Have been shown to use? Do you know what to look for in a protection circuit to prove it is Seiko?

I know keeppower and evva have been shown / confirmed to use seiko through teardowns.

So you’re making a list and checking it twice?

Uh oh. :open_mouth:

All the things they say I did, I didn’t do it!
And all the things I did do, I didn’t mean it!

:santa:

You are forgetting the first one on the market to use Seiko protection IC’s — Redilast

The plan was to make a list of brands/models that The ble community believes to contain genuine seiko circuits. Maybe it makes sense to differentiate between confirmed and probable/believed seikos in the list…

I know there’s a lot of knowledge among blf’ers, so when it comes down to QC’ing the list, I hope, and assume, that we can politely correct each others mistakes and smile about it. :slight_smile:
