Devices whose figures this pack does not meet
Neither maker names the other. These devices publish a draw this pack’s own maker does not rate it to deliver continuously. That is a comparison of two documents and not a manufacturer’s refusal — check both against your own equipment before deciding anything.
Minn Kota's manual for this motor asks for at least a 105 amp-hour rating and says the motor will run on any lead-acid, deep-cycle marine 12-volt battery.
Minn Kota do not say which discharge rate their figure applies to, and Trojan publish four figures for this battery: 83 at the 5-hour rate, 92 at 10, 104 at 20 and 115 at 100.
The 20-hour rate is the conventional marine rating and the one compared.
Minn Kota's website battery guide asks for 110 amp-hours rather than the manual's 105, and they have not reconciled the two; at 104 this battery falls short of both.
Neither company has named the other and nobody has tested the pairing.
Trojan rate the OverDrive 31 AES at 104 amp-hours at the 20-hour rate each, 1 amp-hour short of it.
Their amp-hour figure is asked of the battery rather than of the string, so it is compared against a single one.

Trojan rate the OverDrive 31 AES at 104 amp-hours at the 20-hour rate, 1 amp-hour short of it. Trojan give 177 minutes of reserve at 25 amps, well below the 50 amps Minn Kota state as this motor's maximum draw, and publish nothing at a higher current. Minn Kota's battery-guidance table recommends AGM or lithium at 100 amp-hours for a 55 lb motor, alongside the manual sentence quoted above.
- Minn Kota Terrova 80 lb (60" shaft, wireless remote)Figures compared — they do not meetView device: Minn Kota Terrova 80 lb (60" shaft, wireless remote) →
Trojan give 177 minutes of reserve at 25 amps, well below the 56 amps Minn Kota state as this motor's maximum draw, and publish nothing at a higher current. Minn Kota's manual for this motor is explicit that two 12-volt batteries wired in series are required. Their battery-guidance table recommends lithium at 100 to 125 amp-hours for an 80 lb motor, which is a different chemistry from this one — the manual and the table are both Minn Kota's and they do not agree.
- Minn Kota Terrova 112 lb (60" shaft, CHIRP sonar, wireless remote)Figures compared — they do not meetView device: Minn Kota Terrova 112 lb (60" shaft, CHIRP sonar, wireless remote) →
Trojan give 177 minutes of reserve at 25 amps, well below the 52 amps Minn Kota state as this motor's maximum draw, and publish nothing at a higher current. Minn Kota's manual for this motor is explicit that three 12-volt batteries wired in series are required. Their battery-guidance table recommends lithium at 125 to 150 amp-hours for a 112 lb motor, which is a different chemistry from this one — the manual and the table are both Minn Kota's and they do not agree.
Do not charge with
The manufacturer states these chargers must not be used with this battery:
- PD4500LI Series Power Control CenterStated incompatibleView charger: PD4500LI Series Power Control Center →
Progressive Dynamics state it outright about this converter: "The 4500LI series converter/chargers are designed to recharge lithium iron phosphate (LiFePO4) batteries only. DO NOT USE TO RECHARGE LEAD/ACID BATTERIES!" This pack is AGM, which is a lead-acid chemistry, so their sentence covers it. They say nothing about packs of other chemistries and nothing here extends it past what it covers.
