11/16/2023 0 Comments 100ah battle born batteries![]() Our batteries run in various systems, including marine, RV, van, and off grid! It’s time to upgrade your heavy lead acid batteries to LiFePO4 batteries and upgrade your lifestyle and ability to adventure! Meet the 100 Ah 12 V LiFePO4 Deep Cycle battery, the pinnacle of deep cycle lithium ion battery technology! Our 100 amp hour, 12 volt battery weighs only 31 pounds and is capable of providing you power and relief from battery anxiety. The shipment of this item requires special paperwork/certifications as well as a scheduled ground pick up and cannot be shipped out same day. This item will be shipped via FedEx Ground Shipping in almost all cases. ![]() In case of any doubt about the possible residual current draw, isolate the battery by opening the battery switch, by pulling the battery fuse(s) or by disconnecting the battery positive when the system is not in use.A direct signature at time of delivery is required for this item. The positive supply must therefore be interrupted if a system with Li-ion batteries is left unattended during a period long enough for the battery monitor power consumption to completely discharge the battery. The battery monitor draws <12mA from the battery. This damage can be irreversible.Ī residual current of 1mA for example can damage a 100Ah battery if the battery has been left in a discharged state for more than 40 days (1mA x 24h x 40 days = 0.96Ah). The lithium battery will get damaged if any remaining current is drawn from the battery. At this moment the state of charge can be as low as 1%. Some examples of these loads are alarm systems, standby currents of DC loads and back current drain of battery chargers or charge regulators.Ī residual discharge current is especially dangerous if the system has been discharged all the way until a low cell voltage shutdown has occurred. Damage due to deep discharge can occur if small loads slowly discharge the battery when the system is not in use. Lithium batteries are expensive and can be irreparably damaged due to very deep discharge or overcharge. The discharge floor can be set to a value between 10 and 20%, unless the battery supplier advises otherwise. ![]() However, lithium batteries usually can be discharged significantly deeper than 50%. This setting is used in “the time to go” calculation and is set at 50% by default for lead-acid batteries. In VictronConnect see: Setting > Battery > Discharge floor We recommend setting the charge efficiency at 99%. The charge efficiency of lithium batteries is much higher than that of lead-acid batteries. ![]() In VictronConnect see: Settings > Battery > Charge efficiency factor. Set the Peukert exponent at 1.05, unless the battery supplier advises otherwise. When subjected to high discharge rates, lithium batteries perform much better than lead-acid batteries. In VictronConnect see: Settings > Battery > Peukert exponent. The tail current must be set higher in this case. Some lithium battery chargers stop charging when the current drops below a set threshold. In VictronConnect see: Settings > Battery > Tail current.
