RELiON lithium batteries provide more power than lead-acid batteries, increase performance, and weigh half as much. They can be charged quickly, but a slower charging rate of, e.g. 2-5 hours is recommended. Unlike other batteries, leaving them partially discharged does not reduce their life or long-term performance. Their charging capacity is about 25-50% higher than other models, ensuring prolonged equipment use and preventing voltage drops as the charge decreases.
Maintenance-free, they last up to 10 times longer than their lead-acid counterparts while retaining 80% of capacity after 2000 cycles. They are more temperature tolerant, being able to operate safely up to 65°C, and offer higher performance at low temperatures. Series or parallel connections.
When connecting batteries in series or parallel, please observe the following guidelines:
- Before putting them into service, ensure that each battery does not exceed 50mV (0.05V). This will minimize the possibility of imbalance between the batteries. If they become unbalanced, the voltage of any battery is >50mV (0.05V), relative to another in the set, each battery must be individually charged to rebalance.
- Size the batteries in parallel appropriately: the capacity (rated in hours) when connected in parallel increases by the multiple of the batteries connected (2x, 3x, 4x, etc.). However, the nominal current (discharge and charge) of the batteries in parallel only increases by 75% of the multiple of the connected batteries (1.5x, 2.4x, etc.) (1.5x, 2.25x, 3x, etc.).
- Batteries connected in series charge better than single batteries. Series charging can cause imbalances and reduce operating time, requiring an occasional individual balancing charge.
- Please refer to the RELION document on instructions for series and parallel charging.
LiFePO4 batteries can be discharged up to 100% of their capacity. However, to optimize performance and prevent the BMS from disconnecting it, it is recommended to limit discharge to 80%. Please refer to the battery’s data sheet for the continuous and peak discharge rates of the specific model.
If LiFePO4 batteries are not fully discharged, it is not necessary to charge them after each use; they will not be damaged if left in a partial state of charge (PSOC). They can be charged after each use or when they have been discharged to 80% (20% SOC). If the BMS disconnects the battery due to low voltage at 100% discharge, remove the load to reconnect the battery circuit and charge immediately. It is recommended to store batteries at a 50% state of charge (SOC). Use compatible chargers for lithium batteries, such as ProMariner. When charging from an alternator, check that it is consistent and has the correct charging parameters.
The RB100-HP stands as the inaugural battery to undergo evaluation and approval for use exclusively with specified Mercury Marine® outboard engines. The approval extends to a select range of outboard models, including:
- 2.1L 75-115hp FourStroke, Pro XS® and SeaPro™
- 3.0L 150hp FourStroke, Pro XS, and SeaPro
- 4.6L V8 and 3.4L V6 175-300hp FourStroke, Pro XS, SeaPro, and Verado®
- 2.6L L6 200-400hp Pro and Verado
- 7.6L V12 500-600hp SeaPro and Verado
It's important to note that the RB100-HP lithium-ion starter battery is exclusively approved for use with the mentioned Mercury outboard engines, and caution should be exercised with other Mercury outboards, MerCruiser® engines, and Mercury Diesel engines, as they are not approved for use with lithium-ion starter batteries.
