Even this is not excellent but better than holding an absorption or a float cycle at a dangerous voltage stage. Always confirm how the charger works and the way lengthy the absorption stage shall be. I assume this video done by Sinopoly can sum up the security of LFP technology. Those loopy Chinese guys shot, burned, shorted and cooked these cells.
One possible cause is the plethora of “B” grade or decrease cells being offered to unsuspecting buyers. It isn't uncommon for a custoemr to indicate up right here at the store with cells which might be lacking a emblem, branding, serial numbers and or model numbers. My personal LFP bank is now beyond 1200 cycles (took a really long time and plenty of work to try this) and has exhibited virtually no capacity loss, and no cell drift when working between eighty% DoD and a hundred% SoC. In the primary 50 cycles I actually noticed a minor bump in capacity.
LFP batteries really prefer to be left at mid vary SOC quite than full. Less than half the weight of lead, Ah to Ah, and nearly all the time extra compact.
Take note that a single 60Ah 3.2V cell can throw in extra of 1800A of present into a dead brief. None of the testers got acid burns, have been blinded or went home with holes in their garments. Sulfation is by far and away the most cancers and #1 killer of lead acid batteries on cruising boats. LFP batteries don't sulfate so there isn't any want or worry to continuously get again to 100% SOC before you allow your boat.
A good battery administration system will allow for audible alarms to sound at the time of HVC or LVC and even slightly earlier than as a warning. If you don’t heed this warning the BMS will mechanically protect the bank anyway. What this means is a 400Ah LFP battery rated at .5C can deliver all 400Ah’s at a 200A steady load. CALB cells for example are rated at 1C / 77F so a 400Ah bank ought to ship 400Ah’s with 400A load at 77F. This means a 100Ah battery can provide a 5A load for 20 hours before hitting a terminal voltage of 10.5V.
Lead acid batteries do not prefer to cope with excessive discharge masses such as inverters. When you apply a load larger than the 20 hour Ah score the capability of the financial institution gets smaller. Click the image to make it bigger and see what I imply. With LFP you actually need to supply chargers, controllers and alternator regulators that allow one hundred% customized programming.
