The short answer. The Recon is the one bow mount whose manual spells out lithium: 12 V lithium batteries in series, or a single 24 V or 36 V lithium pack rated for 60 A discharge. Max draw is 55 A RMS at either voltage, the breaker is 60 A within 6 ft, and wire is 8 AWG to 10 ft then 6 AWG. Set the voltage in the motor’s menu; it ships at 24 V.
Set the voltage before you set anything else
The Recon doesn’t sense its bank. It ships set to 24 V and you choose 24 V or 36 V in settings. Feed it 36 V while it’s set to 24 and Lowrance’s warning applies: running outside the recommended voltage “can cause product damage”. The install manual also wants more mount bolts at 36 V (six, against four at 24 V), which tells you how the two setups differ in the designers’ eyes.
Thrust: 90 lb at 24 V, 115 lb at 36 V. Max draw is the same 55 A RMS either way.
Lowrance’s battery wording
From the install manual, in order:
- 12 V deep-cycle marine batteries or 12 V lithium batteries, wired in series. Don’t mix types. If lithium, confirm with the maker that the battery can be wired in series.
- Or one 24 V or 36 V lithium marine battery, confirmed with its maker for trolling motor use “with up to 60 A discharge current”.
- More amp hours or reserve capacity means longer run time. No minimum is given.
That’s the clearest lithium language of any motor on our fit table. It still leaves the size to you.
Packs that meet “up to 60 A discharge”
By our reading of the makers’ sheets, these do:
| Pack | Volts | Ah | Continuous |
|---|---|---|---|
| Pro-Guide 24VM90 24V 90Ah lithium | 24 | 90 | 90 A |
| Pro-Guide 24VM115 24V 115Ah lithium | 24 | 115 | 100 A |
| Pro-Guide 36VM60 36V 60Ah lithium | 36 | 60 | 60 A |
| Pro-Guide 36VM75 36V 75Ah lithium | 36 | 75 | 75 A |
If you’d rather run 12 V batteries in series, Lowrance allows that too; check the battery maker says series is fine, and keep the jumpers the same gauge as the power cables and under 12 in.
Breaker, plug, wire
- Breaker: 60 A manual reset, on the positive, within 1.8 m (6 ft) of the batteries. The safety sheet repeats it as a 60 A fuse at 24 V or at 36 V.
- Plug and receptacle, if you fit them: rated 60 A, weather resistant.
- Cable: the motor comes with 4 ft of 8 AWG. Extending to 10 ft total, stay at 8 AWG or larger. Past 10 ft, 6 AWG or larger. Solder or crimp and insulate every joint.
- Terminals: stainless nuts. Lowrance says stainless wing nuts work loose.
- Order of work: negative off first, on last.
For a run Lowrance’s two lines don’t cover, the Wire gauge calculator gives the drop.
Run time at 55 A
Example, using the Run time calculator trolling math: 80% of the amp hours over the amps, at room temperature.
| Pack | At 55 A | At 27.5 A |
|---|---|---|
| 24VM90 | 1 h 19 min | 2 h 37 min |
| 24VM115 | 1 h 40 min | 3 h 21 min |
| 36VM60 | 52 min | 1 h 45 min |
| 36VM75 | 1 h 05 min | 2 h 11 min |
Lowrance publishes no draw by speed, so 55 A is a ceiling, not a day.
Grounds and other batteries
Lowrance keeps the trolling bank walled off: – Don’t power the Recon from the main engine battery. – Fish finders and depth sounders run off the 12 V engine or accessory battery, never the trolling bank. – No common ground bond cable between the 36 V and 12 V circuits. – A hard-wired foot pedal takes its own 12 V feed with a 3 A fuse, never the trolling bank.
The mount LED reads the bank for you: cyan (24 V) or green (36 V) above 40%, orange from 20 to 40, red under 20, flashing red when critically low. Error V001 means voltage below spec, V002 above.
Charging
Disconnect the motor after each trip and while charging, and never charge with the motor deployed. Lowrance adds a warning other makers don’t: a multibank charger connected to both the trolling bank and the 12 V bank can cause interference through the charger’s common ground. One charger per bank is the safe reading.
Pro-Guide packs charge to 28.8 V (24 V) or 43.2 V (36 V). We don’t list a charger at those voltages yet, or a 60 A breaker. Series wiring steps for 12 V batteries: Trolling motor battery: 12V, 24V or 36V, wired right.
Quick answers
Does Lowrance allow lithium on the Recon? Yes. 12 V lithium batteries in series, or a single 24 V or 36 V lithium pack rated for up to 60 A discharge, per the install manual.
What breaker does a Lowrance Recon need? 60 A manual reset within 6 ft of the batteries, at 24 V or 36 V.
What wire for a 15 ft run? 6 AWG or larger. Lowrance allows 8 AWG only up to 10 ft.
Can I charge both banks with one multibank charger? Lowrance warns it can cause interference through the charger’s common ground. Keep the trolling bank’s charger separate.
