Ok, that miss-print aside, I wanted to confirm the charge rate. My understanding is the “safest” way to charge LiPo is @ 1C, where 1 C = the Amp/hr of the pack. So if this is 400mA/hr, then it will be very safe to charge at 400mA ? Is the correct ?
My 2nd question.
I got some of these (Makerverse USB-C LiPo Charger | Buy in Australia | CE08374 | Core Electronics) to charge the lipo then supply the 3.3V to my project. I am assuming that the battery built in BMS of will protect the lipo from over charge and under draw… i.e. the BMS will do its best to protect the battery. To if I am correct, then with that charger/power board, I can set the dip switches to “10” 400 mA for best use with this setup ?
If that is correct, then I should be able to just plug in the 5V supply and let it do its thing, come back in the morning and unplug to use !
How did I go, does that all sound ok/correct or am I getting things wrong.
The Makerverse USB-C LiPo Charger that you bought has a BMS (Battery Management System) integrated, which is a very good thing! The BMS will handle overcharge protection, over-discharge protection, and battery balancing. It will also ensure the battery is charged safely, protecting it from things like excessive current or over-voltage.
Yeah 1C would be fine, anything under is a bit safer.
Those pouch cells dont have a BMS persay, rather a PCM (Protection Circuit Module).
A BMS keeps the battery healthy, usually programmable meaning you can set a shut-off value to not damage the cells.
A PCM on the otherhand protects everything else (except the health of the battery). It will cut out well below the recommended voltage to prevent anything dangerous happening like fires.
In theory charging them, yes - but as with any LiPo it would be worth supervising them while they charge (in a LiPo bag)
Hi Ahsrab,
I can confirm that the Makerverse LiPo charger does not feature a BMS onboard, but the charging IC should not over-charge the cell.
