The jon boat is loaded, the ramp is busy, and the trolling motor battery has to last the whole morning, which is why the best lithium battery for jon boat use balances amp-hours against the weight you carry to the water. We compared four lithium options from Li Think, LiTime, GRENERPOWER and Enegitech on what each listing states: capacity, BMS figures, weight, stated protections and warranty terms. The Li Think 100Ah leads with 1280Wh, a 150A BMS and a 10-year limited warranty, the LiTime 50Ah is the lighter mid-size pack with 640Wh, the GRENERPOWER 100Ah offers 1280Wh in a Group 24 size, and the Enegitech 10Ah is the lightweight pack for fish finders and small electronics.

Where the points went
The Solar Score weighs performance, build, value, safety and warranty. For a jon boat setup, safety means the BMS protections, ingress ratings and certifications the listing actually states; a pick that states none scores zero on that line. All four state a warranty term: 10 years for the Li Think, 5 years of after-service for the LiTime, 5 years for the GRENERPOWER and 1 year for the Enegitech. Two state an IP rating, IP67 and IP65, and none states a UL or UN38.3 certification. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Li Think 12V 100Ah | 9.8 | 33 | 22 | 21 | 9 | 5 |
| LiTime 12V 50Ah | 9.7 | 30 | 21 | 21 | 7 | 4 |
| GRENERPOWER 12V 100Ah | 9.7 | 30 | 21 | 21 | 6 | 4 |
| Enegitech 12V 10Ah | 9.5 | 26 | 20 | 20 | 5 | 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.
How to choose the best lithium battery for jon boat
Start with capacity and weight
The Li Think 100Ah states 1280Wh at 23.4 pounds, the GRENERPOWER 100Ah states 1280Wh at 23.28 pounds, the LiTime 50Ah states 640Wh at 11.27 pounds, and the Enegitech 10Ah states 128Wh at 1.87 pounds. Match the amp-hours to your motor’s draw and the weight to what you will carry. Our best 12 volt deep cycle battery for trolling motor guide covers more sizes.
| Pick | Capacity | BMS or protection | Weight |
|---|---|---|---|
| Li Think 12V 100Ah | 100Ah, 1280Wh | 150A BMS | 23.4 pounds |
| LiTime 12V 50Ah | 50Ah, 640Wh | 50A BMS | 11.27 pounds |
| GRENERPOWER 12V 100Ah | 100Ah, 1280Wh | 120A BMS | 23.28 pounds |

Read the BMS and temperature lines
The Li Think lists a 150A BMS that stops charging at 32 degrees F, resumes at 41 degrees F and adds self-heating, which needs a charging current of 10A or higher. The LiTime lists a 50A BMS with low-temp charging cutoff. The GRENERPOWER lists a 120A BMS with cold protection and auto cut-off and recovery. The Enegitech lists a 10A BMS with charging from 0 to 55 degrees C and discharging from -20 to 60 degrees C. Our best battery charger for trolling motor guide covers keeping any of these charged.
Watch the limits the listings give
The Enegitech is rated for devices up to 128W and must not be connected in series or parallel. The Li Think supports expansion up to 4P4S and is not for starting gasoline engines. The LiTime is not for starting batteries, golf carts or jacks, and the GRENERPOWER is for energy storage use only, not for cars, starting or golf carts. Our best deep cycle battery for 24 volt trolling motor guide covers higher-voltage setups.
