LiPop Battery Pack DIY Question

[Nanik]

Hi,

Got a TOSHIBA battery pack today on discount for $1 from JBHiFi and thought of using it for my son's Nexus 9 tablet battery pack. I've googled around and found info about the battery

http://www.sourcingelectricals.com/SANYO-UF404251S-1020mAh-Lithium-ion-Battery-10185652/

According to the website the battery is 3.7v 1020mAh. After reading on LiPo charger it makes sense to get a charger + balancer for the batteries. Found the following which says a charger + balancer for 3S - https://www.aliexpress.com/item/3S-25A-lipo-lithium-Polymer-BMS-PCM-PCB-battery-protection-board-for-3-Packs-18650-Li/32767793292.html anybody has any experience with this, interested to get feedback about this ?

Thanks for the help

Are you going to remove the individual batteries? That pack doesn't output 3.7v as is. Does the pack already have charging circuit built in?

Not planning to take them apart but more thinking of replacing the PCB board with the one from Aliexpress. From the look of it the batteries are configured as 3S2P

Perhaps someone can share their experience charging/discharding LiPo using equivalently similar kind of board?

Thanks
