How we scored them
The Solar Score weighs capacity and voltage, cycle life and durability, value, safety, and warranty. All 3 are batteries. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| LiTime 24V 100Ah LiFePO4 | 9.8 | 35 | 25 | 22 | 8 | 3 |
| Mighty Max ML100-12 GEL | 9.6 | 30 | 20 | 19 | 7 | 2 |
| Mighty Max ML55-12 GEL | 9.5 | 29 | 19 | 18 | 7 | 2 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
LiTime 24V 100Ah LiFePO4
The LiTime is a 24V 100Ah lithium battery for trolling motors. The Bluetooth 5.0 shows SOC on your phone. The 6000+ cycles at 100% DoD last up to 10 years. The IP65 rating protects against water. The 5-Year Warranty is good.
Mighty Max ML55-12 GEL
The ML55-12 is a 12V 55AH GEL battery. The UL certification assures quality. The GEL paste resists vibration. The 1 Year Manufacturer warranty is standard. It suits smaller trolling motors.
Mighty Max ML100-12 GEL
The ML100-12 is a 12V 100AH GEL battery. The 59.2 pounds is heavy. The UL certification assures quality. The 1 Year Manufacturers Warranty is standard. It suits larger trolling motors.
Which should you choose?
Choose LiFePO4 if you want long cycle life and light weight. The LiTime has 6000+ cycles and Bluetooth. Choose GEL if you want lower cost and simple maintenance. The Mighty Max batteries are UL certified.
For 24V trolling motors, the LiTime is the direct fit at 24V 100Ah. For 12V systems, the Mighty Max GEL batteries work: the ML55-12 suits smaller trolling motors, and the ML100-12 suits larger ones with its 100AH capacity. Match the voltage to your motor first, then size the amp-hours to your runtime. A battery that cannot hold your motor voltage is the wrong battery at any price.
What to check before you buy
Start with voltage: the LiTime is 24V, and both Mighty Max batteries are 12V. Your trolling motor takes one or the other. Next check capacity against your runtime: 55AH on the ML55-12 suits short trips, while 100AH on the ML100-12 and the LiTime suits longer days. Then weigh the trade-offs: the LiTime lists 6000+ cycles and Bluetooth monitoring with a 5-year warranty, while the GEL pair lists UL certification and a 1-year warranty. Finally, check the weight: the ML100-12 lists 59.2 pounds, which matters if you carry the battery to the boat.
Sizing Notes
- Match voltage to your trolling motor.
- Check amp-hour capacity for runtime.
- Consider weight for portability.
