  • Solar powered LiPo charging station

    correct that solar li-ion bank

    could never get them to work with inbuilt pcb mine are all stripped then soldered into a pack of 3s20p youtube solar li-ion and you should find my videos and progress i ant done any vids for abit as been nothing really updated

    been running a battery made from slabaged laptop batterys now on solar with varying forms on li-ion controller home made cc/cv units now a proper controller and never had a problem they are not as dangerous as people make out they are if a 50 tun press can crush one with out exploding they damn same only time they are bad is if you short them out

    the laerger the wattage of solar panel the better this way you have a more stady power output

    you can get li-ion solar charge controllers so you can charge the li-ion direct i have a 44ah battery pack i charge like this for running my computer and lighting

    DIY Power Bank ?

    i only so the first half with the charge controller and the boost converter i had not scene the part of this tut where you use the salvaged unit so all my comments where to the diy unit not the salvaged unit

    the protection circuit is to stop over discharge from the boost circuit i was not refering the the charge pcb tsp 2511 in this image it does not have battery protection for over discharge it is a charging unit not charge and battery protections

    they dont hald make some bold claims about capacity on these battery banks i had a few claim to be 20000mah and or only 2000 mah

    as long as the boost circuit is set to 5.2 volt they will be no damage and protection cirsuit is only needed for the first idea to stop over discharge

    i was refering the the li-ions charge circuit and boost circuit not the salvaged board from battery bank

    you have no protection circuit for the cells so they is a very good chance you could over discharge the cells and kill them

  • Fast, Cheap and Modular Lithium Battery Charger System

    but you are also using a power supply to drop from 110-230 down to x volts then dropping that for each different pack formation advantage of mine is not only will it charge mutliple different packs but also can be a bench power supply to power lots of diferent things and can be used to charge any form of battery

  • Fast, Cheap and Modular Lithium Battery Charger System

    i know a far cheaper one quite simples laptop power supply cc/cv step down converter set to 16.8 volt as that is max voltage of a 4s pack and a volt meter display thes is best to have on battery along with the 4s pcb for over discharge protection and done this would cost about 10 bucks

    also with a dc conveter you only limit is what the power pack puts out

    17 volt is to much you would over charge the cells at current i have solar panels that run into a dc step down converter set to 12.6 volt i have a 3s protection circuit for stopping over discharge
