Ik heb net dit geweldige item op AliExpress gevonden. Bekijk het nu! €4.29 48％ Off | Turmera 3240 Isolatie Epoxy Plaat 0.5Mm Dikte 203*172Mm Voor 3.2V 280ah 320ah 310ah 90ah 12.8V Lifepo4 Batterij Diy Gebruik https://a.aliexpress.com/_m0n399e Or those

Nkon is going to reweld it for free So i get the new top balanced cell back They where prepared to swap the cell but better get my charged cell back ?

Top balance done on my 4s pack My eve 105’s aint coming close after a top balance of same voltage measurement those are exactly the same Now longer term testing wil bring more information Capacity doesn’t matter for me if it’s around 300ah it’s fine for me After discharging for 60seconds...

Got them wired up charging now 3mm bloated +- I’m curious when fully charged i wil do a top balance by wiring them parralel again..

3 times with strong tape and insulation boards between

How deep can i dril……. Can do it 100% steady and correct got all the tools at work ..

It’s for an electric motor for my boat So i will use a car light to get some amp’s out the specific cel And the clamps where just for loading a second to test it Now it’s buile with anderson 50amp connector to load

Indeed just testing em for fishing Not capacity testing no need for 5more or less then described haha I’m happy as they stay at the same voltage with my daly bms ?? otherwise active balancer is added

Yes need to take apart my pack It was the last screw from the pack that broke of..

I got a fix Can let it re weld it at nkon for free So that’s the best option for sure Hope no other terminals come of next time Maybe they wil weld all terminals again

How do you know they are balanced

Hello A week later used the battery 1time till half and loaded the battery with 20ah This is the result

Intressting to read Maybe later i build a solar battery for my house if i got a house ? Now this is only for my bellyboat (fishing) 200amp battery and already used once 100amp out of it

I ordered 4cells to test em for a 12v battery for fishing and the coolbox inside my car (charging with solarpanel 405w on top of car ?)

Any link’s for new cells on alie or alibaba trusted seller’s so i can compare with What tewaycell is offering me.. Got 4 202ah batteries from tewaycell They were brandnew pulling out the capacity But they don’t sell 25ah batteries But can create a paylink for them from another salesman.. but...

Forgot to tell I’m from Europe

Are my cells balanced good enough? Or do i need to balance them more This is my first battery build

It’s now with 50ah anderson build to load it Was just to test it So unload with car light the specific cel and load again?

Belgium why?

Indeed 76€ each i payed got them from Tuesday morning Just 4 cells to test em out

My bms is now at 3.6v each cell set so can’t go over 3.6 Maybe put on 3.65

So the high voltage protect is set on 3.6v Maybe put it on 3.65 so the cell high voltage alert triggers later?

Charge voltage is from lifepo4 loader got a 5 /10 /20 ah loader So balanced current null Battery strings 0 What does that need to be put on I’m now going home so wil put it correctly when i’m home

It does expend lifetime for sure But for my use it’s not possible to compress it wil have a 400-700 cycle in 10years so i don’t care if it’s losing lots of capacity i make a new one Putting it in a hardcase with no space around for compression Using it for bellyboat fishing and compressor...

These are normally grade a cells from tewaycell 200ah cells I got them pretty good at the moment i think Now i gonna see how it goes after few decharges and charges This was last charge at 3.58 the bms needed to stop the cells So pretty happy with that result

Yes but i now i know some more things And hopefully my cells are good and long lasting quality ?
