Battery Capacity & Current

The SOK 200Ah has a capacity of 2,636Wh or 206Ah at an operating voltage of 12.8V. It has the same maximum charge current and discharge current as the SOK 100Ah model and can also be connected in series or parallel.

Internal design, Built-in Smart BMS & Higher Life Cycle and Warranty

All these features and specs of the SOK 200Ah battery are similar to the 100Ah battery model, with the only exception of being bigger and wider in design.

SOK Batteries vs. Lion Energy UT 1300

So, now that we can understand the specs and features of the SOK battery models, we can compare both SOK models with The Lion Energy UT 1300 battery, a leading LiFePO4 battery competitor.

Lion Energy Battery

Size & Weight

The Lion Safari UT 1300 battery features a weight of 23lbs and a size of 10.2×6.6×8.8in, making the Lion Energy battery a lighter and smaller battery when compared with both SOK battery models, which means it is easier to handle.

Operating specifications

Batteries from the Lion Energy battery provide a maximum charge current of 100A and a maximum discharge current of 150A and up to 900A for surges. The SOK batteries have the same maximum charge current of 50A and discharge current of 100A and up to 200A for surges. In this aspect, SOK batteries can’t stand against the Lion Energy Battery. The Lion Energy battery is more suitable for applications that need higher instantaneous currents to work medium size DC or induction motors. However, refrigerators or freezers with lower surge currents could be powered using the SOK batteries.

SOK models have a temperature performance of (-22~140°F) for discharges and (32~140°F) for charges and a BMS Low/High-temperature cut-off of 32°F/149°F respectively. On the other hand, Lion batteries have an operating temperature range of (32~113°F) for charges and a range of (-4~131°F) for discharges.

The three batteries have a charge voltage of 14.6V. At the operating voltage of 12.8V, the competitor Lion Safari battery has a capacity of 105Ah. The SOK 100Ah battery has a slightly lower capacity than the Lion Safari, but it’s cheaper and can withstand higher temperatures.

Warranty & lifecycles

Lion Safari battery warranty surpasses standards by providing lifetime warranties and ensuring the proper functioning of the battery for a minimum of 3,500 cycles (100% DOD). On the other hand, both SOK batteries provide a 7-years warranty, but both ensure the proper functioning of the battery for a minimum of 4,000 (100% DOD) cycles and a lifetime of customer support. In normal usage (80% DOD) Lion Energy battery provides 5,000+ cycles while the SOK batteries provides 8,000+ cycles.

Depth of discharge (DOD) indicates the percentage of the battery discharged relative to the overall battery capacity.

The SOK batteries have more charge and discharge cycles than the Lion Energy battery before losing performance. In other words, SOK lasts longer than the Lion Energy battery.

Prices

While the Lion Energy battery has similar operating specifications to the SOK 100Ah battery model, the price is almost double ($999), while the 100Ah costs $500. The SOK 206Ah battery is $1029, a similar price to the Lion Energy product but with more capacity, making SOK batteries a much cheaper option.

SOK Batteries vs. Battle Born

Now we will compare specifications and features of SOK batteries models with batteries from another leading competitor, Battle Born, specifically the 100Ah 12V LiFePO4 Deep Cycle Battery.

Battle Born Battery

Figure 4. Battle Born 100Ah 12V LiFePO4 Deep Cycle Battery – Source: Battle Born

Size & Weight

The Battle Born 100Ah battery surpasses the weight of the SOK 100ah battery with 31lbs and exceeds the length of both SOK batteries with its dimensions of 12.76×6.86×8.95in, making Battle Born heavier and larger yet narrower than both SOK models.

Operating specifications

Battle Born 100Ah batteries provide a discharge current of 100A, a charge current of 50A, and up to 200A for surges, the same currents that both SOK batteries have. The Battle Born battery has an operating temperature range of -4°F to 135°F and BMS Low/High-temperature cut-off of 25°F/135°F respectively. They also have water resistance which is a feature that SOK batteries don’t.

When comparing the 100Ah SOK battery to the Battle Born one, both batteries have the same discharge/charge/surge currents and capacities. Temperature performances are also very similar to one another. The only difference would be that the Battle Born battery has water resistance, making it more suitable for marine applications than the SOK model.

Warranty & lifecycles

The Battle Born batteries have a 10-years warranty and work at least 3000 cycles (5000+ at 80% DOD). The SOK models are far more durable batteries; however, they have three years less warranty coverage than the Battle Born one.

Prices

Battle Born battery has similar operating specifications to the SOK 100Ah battery model but has a 50% higher price ($799).  On the other hand, the SOK 206Ah battery costs $1029 but has way more capacity than the Battle Born battery.

Conclusion

The Lion Energy battery has better design features, currents, and warranty, but the SOK battery models still count with high-quality features that guarantee you higher lifecycles at a much lower cost. Battle Born’s features are similar to the 100Ah SOK ones; however, the Battle Born one has lower lifecycles. 

The Battle Born battery is also more expensive than the SOK 100Ah model and only surpasses SOK models in warranty coverage and resistance against water. If we make a balance out of this, the SOK batteries will provide you similar specs, will last longer, and cost much less for the equivalent amount of energy, making SOK batteries a much better choice than the Battle Born ones.

Both SOK models are great options if you are looking for a battery for any application of mid and high-demand.
