Devices documented to run on this
Some rows below are marked FIGURES COMPARED. On those the figures line up and neither manufacturer states that the pack runs the device — that is our reading of what each of them published separately, not a claim by either of them or a test by us. Even where every stated figure agrees, these can still decide it:
- The device’s published draw is usually a peak, not the load it holds — the two numbers are not the same kind of quantity
- A maker’s amp-hour minimum and their reserve-capacity minimum can give different answers about the same battery
- Conditions attached to the chemistry, such as a speed limit for running on lithium
- Whether the pack may be wired in series at all, where the device needs 24 or 36 volts
- The charger, which both makers put conditions on and neither supplies
- Case size, hold-down and terminal type — fitting the space is not being secured in it
Worth confirming with the device's manufacturer or a dealer before buying.
One of these, on its own, at 12 V.
Two of these, identical to each other, wired in series for 24 V.
Two of these, wired in series for 24 V.

“This product is suitable for 12V trolling motors up to 70lb thrust; 2*identical batteries in series for 24V trolling motors up to 100lb thrust; 3*identical batteries in series for 36V trolling motors up to 120lb thrust.”
Only within LiTime's ceiling of 70 lb of thrust for a 12 volt motor — check yours before buying. The rows below without a line of their own are within that ceiling.
Only within LiTime's ceiling of 100 lb of thrust for a 24 volt motor on two packs in series — check yours before buying. The rows below without a line of their own are within that ceiling.
Only within LiTime's ceiling of 120 lb of thrust for a 36 volt motor on three packs in series — check yours before buying. The rows below without a line of their own are within that ceiling.
The packs must be identical to each other — the maker's rule says so, and mixing capacities or ages in series is how one cell group ends up carrying the bank.
Minn Kota publish a maximum draw of 58 A for this motor and say it occurs only intermittently; LiTime rate this pack at 50 A continuous, 60 A for up to thirty minutes and 250 A for one second. This motor's own manual says the QUEST series is optimized for LiFePO4 cells, so the 85% speed limit its older siblings carry does not apply to it. The packs must be identical to each other, the same brand, and bought within a month of each other — LiTime will not support a string mixed from different ages or makers.
The two makers do not agree here. The battery maker's thrust rule covers this motor, but the motor's own documentation asks for 60 A continuously and this pack is rated for 50 A. Both statements are recorded; neither has been resolved in favour of the other. The packs must be identical to each other — the maker's rule says so, and mixing capacities or ages in series is how one cell group ends up carrying the bank.
The battery maker's own rule covers this motor, quoted above.
The motor's maker asks for at least a 105 amp-hour rating, and this pack is 50 Ah.
Both statements are recorded and neither has been resolved in favour of the other.
Minn Kota add a condition LiTime do not: this motor is designed for lead-acid, and running it above 85% speed for a prolonged period on lithium could cause permanent damage to it.
The packs must be identical to each other, the same brand, and bought within a month of each other — LiTime will not support a string mixed from different ages or makers.

Compatible platforms
These figures match. Nothing states that the packs are interchangeable — that is our observation of published specifications, not a claim by the manufacturer or a test by us. Even when every stated figure agrees, these can still differ:
- BMS communication — many packs authenticate with the platform over a data bus
- Maximum discharge current, which the capacity figure does not express
- Pin assignment inside an identical connector shell
- Mounting rail, lock and cradle — a shared case is a shared shape, not a fit
- Firmware or serial pairing, where the manufacturer uses it
Worth confirming with the manufacturer or a dealer before buying.
