/products/manufacturers/wuerth-elektronik/b/blog/posts/charge-time-reductionSir i am making a 60V battery pack with 3.2V and 10A small battery cell. And the battery takes lot of time to charge with 3.5 V charger that i am useing now, I reasearched to increase the charge speed I got to know Traditional 12V charger can be useden-USTelligent Community 12https://community.element14.com/products/manufacturers/wuerth-elektronik/b/blog/posts/charge-time-reductionSat, 21 Aug 2021 19:35:42 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:6830bafd-aeff-4193-a63b-7cc77f7dcbfeDAB0<p>I agree with Douglas.</p><p>&nbsp;</p><p>You do not want to fool around with charging any lithium based battery.</p><p>Now I have seen some articles where people have built a cooling system for the batteries, which can allow them to be safely charged faster, but it requires very precise monitoring of the battery temperature.</p><p>&nbsp;</p><p>DAB</p><img src="https://community.element14.com/aggbug?PostID=11678&AppID=30&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/products/manufacturers/wuerth-elektronik/b/blog/posts/charge-time-reductionSat, 21 Aug 2021 18:41:38 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:6830bafd-aeff-4193-a63b-7cc77f7dcbfedougw0<p>12V would likely destroy a 3.2V battery.</p><p>Optimal high speed charging requires controlling the current and adjustment based on battery temperature and voltage.</p><p>It is difficult to optimize charging cells in series, since each cell is different.</p><img src="https://community.element14.com/aggbug?PostID=11678&AppID=30&AppType=Weblog&ContentType=0" width="1" height="1">
