instead of the spot welder, i uses a Goot 40w soldering iron with boost mode. When the iron is hot, a quick 3 second dab on the terminals is good enough without heating up the liOn battery.
@@peejae082004 I understand and I do have the model you mentioned. However, I think it’s a bad idea to make a power bank with swappable batteries. It is because they draw a huge current and that can cause heat and possibly spark because of the ‘contact resistance’. Littokala model may be okay because of lower output, but for 45 watt power banks, I don’t think so.
Probably the only cells that could handle 45W charging in two pieces are Samsung 30T, but again that would drastically limit the capacity of the power bank.
the overheating issue is from soc ip5386. look no heatsink in soc.if heatsink under pcb if used alumunium pcb,the baterai to hot from pcb it self. sorry my english is so bad
Hmm. You could be right. I never thought about that. But on the other hand, the temp. measurement comes from the probe attached to the batteries, and the thermal throttling happens according to the measured temp. Isn't that so?
@@Tinker_Box ya. I test with ip5318 with output 65w from soc but from pcb i buy 60w max.i cooling soc with thermal pad and alumunium case.its almost throttle at 42⁰c on soc and baterai is fine around 40⁰c to 42⁰c and ready to drop power its charging around 45w. Yeah its compicated to solve problem on small area even in large area almost overheating on soc. Ip5386 its fine if soc add thermal pad and alumunium case. Sorry my english so bad bro 🙏🙏🙏
45w for 2 batteries in an enclosed box, lol. This works best for 2s 3p configuration to distribute the load. At almost 7.5 A, each cell puts too much stress on the batteries during charging. Whoever designed this was probably drunk when he made it, hahaha. Edit: For people who charge at 20 w below, you can use power bank modules like IP5328P. It is simpler and compatible with a 1S battery setup. I'll wait for this IP5386 boards to drop their price so that I can use my recycled cells from e-bikes and include an 2S active balancer. 25 USD is too much.
In the datasheet from the ic can support up to 4s, but the module only in 2s, it's not wort to buy the module at 25 usd lol... more battery in series more effecient and reduce the stress why the disigner the pcb not just used 4s configuration😂

It's great, shows so comprehensive details on display!

I wish they'll release a solderless version of this (like the Liitokala Lii-MP2). Maybe 2S 2P for 45W.

Nice power bank I would use the Samsung 50s
I would not trust LiitoKala for high performance use. I just use them for normal power flashlights. Better to use better cells like Samsung or LG.
@@robert0joe Good idea..
thanks for the video .
btw u should try to add heatsink on the top of soc(ip53??)
@@starea727 There’s no space.
The first channel atleast say something about the board,the subtitle help me understand the video,and the video so relaxing
Thanks!
Man. watching this video reminds me of my Mymosh SX-Pro Energybank. It was lost and never found :(

You’re right and thanks for the info. But as I talked in the video, it really doesn’t matter much in real usage. 😄

@@m.a.pansuriofficial great info! Thanks.
What batteries were used?
@@Tinker_Box i used samsung 21700 5.000 mah in 5S.because is max capacity to apply in plane flight🙏🙏🙏

This is support samsung super fast charging ?
@@rheynaldyrama9978 Yes it does
Link of the powerbank blue please
If the link in the description isn’t working, I think the seller can’t ship it to your country.
Any link to this website 1.41?
It’s been a while since I made this video, but I believe I’ve searched with the chip numbers such as IP****. Sorry sir.
