if you dont want to risk it then jimmy can fix it for a fee https://ebikebatteries.co.uk/

no that wont work for heat you need amps and voltage same as speed from a ebike motor @ 5v 1amp they get warm in about ten mins on full power, with 8.4v and 2.7a they heat up in seconds on full power. :p

you can unplug it and then test each bank via the pins black is - and the rest positive, do not sort the pins with the multimeter probes!

watch a few of his vids and you will get the idea ;) just dont short anything or you will go kaboom or kill the bms.

4 will fit that way but getting a bit to heavy with that many and not going to get any of those cells for cheap any time soon. all i need is about 1 hr so 2 new 2500mah should just about do it...

im not it will just be 2 cells for 8.4v with a 2s bms but how long did the original seal skin batts last ? and what sort of amps do they pull from the batts ?

the bms manages the charging and balancing of the cell groups if one group goes out of balance then the batt wont fully charge and take a hit when you try and pull full load under power and get voltage sag. the batt looks ok from the pics as if it was wired wrong would not change at all as the...

decent batts are expensive and i doubt the ones for 60 quid wont last that long so planned on making my own anyway as simple and cheap enough for me to do anyway. now how long they will last is another thing but they want more power than 5v at 1amp as went as high as 2.7a from my other pack...

yes they came with 2 batt boxes for 3 aa batts and have taken the pcb out of it and wired it to a usb cable so can use the power bank. and it looks like the same connector as in the ebay link but fook 14 quid lol ill just chop it off and use one i have here when i make the new batt. 3 cells...

my mum ordered them but i think this is the link, note it says comes with the 3 batt aa box that just turns the leds on lol...

i did as tried a 5v 2a power bank and still did nothing heat wise and only came to life when i used my 8.4v 6 cell power bank and then started to get warm. these are the batts that are to be used with them but no idea if they have a bms...

yes and went in the bin years ago as dont like lipo batts ;)

id put a more powerful pump on it tho ;) :p

adr from 2021 for all other vaccines was 39k for covid alone it was 675k.

why im going to wait for a bms ;) there is nothing in that black box bar a on switch and a led, i also doubt any bms is in the gloves either.

and look what you get :rolleyes: 150ma of pure power to warm your hands o_O tho not all is lost as they do work with the right amount of power just they want 8v and 2.7 amps and get warm fast so need to make a 2s batt with some 18650s i have just waiting for a bms to show up to put one...
