Review request for HKJ [Rechargeable Batteries]

16340 LiFePO₄ cells.

Thanks dude. You have to buy a separate charger though. Guess I’ll just go with throwaway cr123a’s for now.

Barkuti · January 15, 2019, 5:19am

Not really a problem, there are inexpensive and good chargers which can cope with LiFePO₄ cells. As most notable examples the LiitoKala Lii-202 and Lii-100. This is not for sloppy users, to charge LiFePO₄ cells you will have to press the MODE button to swap charging mode to Li-Fe upon cell insertion. A very easy thing to perform once accustomed.

Choosing this path will make you save money sooner or later; quite soon I'd say given the price :facepalm: of CR123A non-rechargeable lithium cells.

Cheers ^:)

Molicel P26A 18650?

I also searched for a European source for the 4000mAh 21700 Molicel P42A but could not find one.

I have 3 Molicel in queue, the P26A will probably be published this month.

Here : Molicel P42A 21700 | Fogstar | Official UK Molicel Distributor

In Great Britain, a little expensive, but the only one and NPE approved so Grade A Cells guaranted.

And Fogstar.UK has the same batch of Molicel P42A than Li-ion Wholesale visibly, look at her pictures!

HKJ, I want to thank and compliment you on the new filter functionality on your site.
Helps lot in my searches!

I miss O:) EAIEP, they should be about cooked now don't they?

HKJ · February 19, 2019, 8:11am

Not yet, they are still in the queue.

Quick question for Henrik: how/where did you got the Turnigy sub-C 5000mAh cells you reviewed? May need a cheap way to get one or two.

I recently bought two 7,2V Turnigy Stick Packs made with them, for drill battery pack restoration. After dismantling the packs measured all cell voltages, all of them were close to 1,3V except one at 1,235V. Re-raised its voltage to 1,304V and I have it under observation, but looks like it self-discharges :| quicker than the rest.

Cheers ^:)

From a Swede, but I believe they are sold by Hobby king.

Hello HKJ,

I know, that it is not rechargeable, but did you consider reviewing the Soshine AA and AAA 1.5V lithium primaries? For some low drain applications, those could be a good choice as an ‘alkaleak’ replacement.

HKJ · February 23, 2019, 6:45am

Depends on price and availability.

adam7027 · February 23, 2019, 9:09am

You can get them here and here .

HKJ · February 23, 2019, 9:14am

I have ordered some

adam7027 · February 23, 2019, 1:24pm

Thank you, I’ll be curious of your result

HKJ · February 23, 2019, 1:29pm

It will be some time, I took the slow boat option.

Barkuti · February 23, 2019, 3:15pm

At the given price for those lithium primaries I can buy a bunch of alkalines (a lot really), and if I were to worry I'd laminate them LoL.

In my experience I've rarely seen leaking alkalines, something which can happen to a very minor extent when AC recharging them, and their consecuences aren't terrible either. I've even had alkalines in vintage toys without issues, yet I preserve stuff well.

I really see no point in buying lithium primaries other than financing unworthy dubious technologies.

Cheers

Hi HKJ,
I have bought a pair of these 16340 batteries and they perform surprisingly well and I wonder how they compare to the AW 16340 15C that you tested a few years ago.
