jvniekerk.it Posted January 19 Share Posted January 19 https://powerforum-store.co.za/collections/batterys/products/r9-51-2v-220ah-11-2kwh I currently have this battery installed and would like to know why its charge current curve is as follows 0 - 90 = 100A 91 - 95 = 10A 95 - 96 = 5A 96 - 100 = 3A This makes a full charge near impossible since 96 - 100 takes 2 hours 45 minutes if conditions are perfect and there are no clouds. In the example here it takes 4 hours to complete its like this the same time as Gel/Lead acid in its absorption phase Quote Link to comment Share on other sites More sharing options...
jvniekerk.it Posted April 23 Author Share Posted April 23 Found the reasoning behind this it uses a Pace bms with a charging balancer. The restrictions are built into the bms in order to give the cell balancer time to do its work. When the imbalance between the cells are higher the limit charge current will be lower. Hope this helps someone. Used the following to access the cell voltages etc. Pace PBMSTools https://cdn.shopify.com/s/files/1/1249/8241/files/PbmsTools_V2.5EN.zip?v=1600336921 Cable https://solar-assistant.io/shop/products/pace_rs232 Drivers https://cdn.shopify.com/s/files/1/1249/8241/files/CDM21228_Setup.zip?v=1621934743 Scorp007 1 Quote Link to comment Share on other sites More sharing options...
