Best trolling motor battery setup: battery, charger and circuit breaker that work together
Updated 2026-11-11 · Kit: 24V bass boat, most anglers: $542.64 in the cart after Redodo's automatic discount (tested 2026-11-13), one link that opens its checkout with both in the cart: https://dealectric.com/go/kit-24v-one-battery
Short answer. The best trolling motor battery setup for a 24V Minn Kota is Redodo's 24V 100Ah lithium battery plus its own 29.2V charger: Minn Kota chargers can't charge a single 24V or 36V lithium battery, and its 100 A continuous rating covers a QUEST motor's 60 A max draw.

What the differences mean
- Current headroom. 24V kits: 100 A − 60 A QUEST max = 40 A spare. 12V kit: 120 A − 50 A (55 lb 12V max) = 70 A spare. Redodo 36V 50Ah on a 36V QUEST: 50 A − 60 A = 10 A short.
- Refill time. 24V 100Ah on a 20 A charger: 100 Ah ÷ 20 A = 5 h. 12V 120Ah on a 20 A charger: 120 Ah ÷ 20 A = 6 h. A 12V 100Ah lithium on one 10 A bank of a Minn Kota MK 330PCL: 100 Ah ÷ 10 A = 10 h.
- Full-throttle runtime. 24V 100Ah at 60 A: 100 Ah ÷ 60 A = 1.7 h. Redodo 36V 50Ah at 60 A: 50 Ah ÷ 60 A = 0.83 h, and its BMS allows 60 A for 30 minutes at most.
- Cost per watt-hour. 24V kit: $579.98 ÷ 2,560 Wh = $0.23/Wh. Group 31 bundle: $674.48 ÷ 2,560 Wh = $0.26/Wh. 12V kit: $379.98 ÷ 1,536 Wh = $0.25/Wh.
- What the compact case costs. $674.48 − $579.98 = $94.50 extra for the Group 31 size and Bluetooth.
| Your boat | Pick |
|---|---|
| 24V motor (70–100 lb, or a QUEST 90/115 wired for 24 V) with room for a full-size battery | 24V one-battery kit |
| 24V motor, Group 31 tray, little deck room | 24V Group 31 bundle |
| 12V motor of 30–70 lb on a kayak or jon boat | 12V kit |
| 36V QUEST or 112 lb motor | Three 12V batteries in series on a 3-bank charger (see below) |
Most bass boats run a 24V motor, and the cheapest complete 24V cart is the one-battery kit: Redodo's 24V 100Ah with the 29.2V 20A charger, $579.98 together. The kit: 24V bass boat, most anglers (Redodo 24V 100Ah LiFePO4 Lithium Battery + Redodo 29.2V 20A MINI LiFePO4 Battery Charger for 24V lithium batteries): $579.98 on redodopower.com, $542.64 in the cart after Redodo's automatic discount (tested 2026-11-13), one link that opens its checkout with both in the cart: https://dealectric.com/go/kit-24v-one-battery
If your tray is Group 31 size and space is tight, Redodo sells its smaller 24V 100Ah with a 24V 20A charger as one SKU. Measure first: Redodo says it fits Group 31 trays but not standard Group 31 battery boxes. The kit: 24V, tight Group 31 tray (Redodo 24V 100Ah Group 31 Trolling Motor Bluetooth Lithium Battery): $674.48 on redodopower.com, $634.02 in the cart after Redodo's automatic discount (tested 2026-11-13), one link that opens its checkout with all 1 in the cart: https://dealectric.com/go/kit-24v-group-31-tray
For a 12V motor, the 120Ah Group 24 battery drops into Group 24, 27 or 31 boxes, and its 120 A rating leaves wide headroom. If your boat already has a Minn Kota PCL charger, it can charge a 12V LiFePO4 battery, so you can skip the charger in this cart. The kit: 12V kayak or jon boat (Redodo 12V 120Ah Group 24 Trolling Motor Bluetooth Lithium Battery + Redodo 14.6V 20A LiFePO4 Battery Charger for 12 V lithium batteries): $379.98 on redodopower.com, $362.17 in the cart after Redodo's automatic discount (tested 2026-11-13), one link that opens its checkout with both in the cart: https://dealectric.com/go/kit-12v-kayak-jon-boat
The charger and the 60 A check
Charger. Minn Kota states that its chargers 'are not compatible with single 24V and 36V Lithium Batteries' and that they 'are designed for 12 Volt battery systems only'. Each bank charges one 12V battery, and batteries wired in series can't be charged on one bank. If you keep two or three 12V batteries in series, a Minn Kota multi-bank charger still works, one bank per battery. Its maximum is 14.5 V, so check that against the battery maker's charge voltage. If you switch to one 24V or 36V lithium battery, you also need a 29.2 V or 43.8 V LiFePO4 charger. That's why each 24V kit above includes one.
Current. Minn Kota says QUEST motors 'are designed to not pull more than 60 amps on high speed' and that breakers larger than 60 A should not be used on them. It also says a lithium battery without enough continuous current shows up as a motor that runs for a short time and then shuts off. The battery's continuous rating, not its peak, has to cover the motor's max draw. Put a 60 A breaker such as Minn Kota's MKR-27 between the battery and the motor. Redodo doesn't sell one, so buy it separately.

| QUEST 36V | 60 A | 60 A | Minn Kota Ulterra QUEST manual |
| 80 lb, 24V | 56 A | 60 A | Minn Kota wiring guide |
| 112 lb, 36V | 52 A | 60 A | Minn Kota wiring guide |
| 101 lb, 36V | 46 A | 50 A | Minn Kota wiring guide |
| 55 lb, 12V | 50 A | n/a | Dakota Lithium, citing Minn Kota |
For a 36V QUEST or a 112 lb motor, Redodo sells no single 36V battery rated for 60 A continuous. The practical route is three 12V lithium batteries in series on a 3-bank charger, one bank per battery. Before you buy, check that each battery's continuous rating covers the motor's max draw and that its maker allows series wiring.
Not recommended
Redodo 36V 50Ah on a 36V QUEST or a 112 lb motor. Redodo markets it for 100–120 lb motors, but rates it at 50 A continuous and 60 A for up to 30 minutes. That is below the 60 A a QUEST can pull and the 52 A Minn Kota lists for a 112 lb motor, so hard Spot-Lock or full throttle can trip the BMS. It suits a 101 lb, 46 A motor.
