I'd recommend watching the videos that Boatman have made around care for the boat and its batteries. Oh and order one of those little adapters (about a tenner) so you can drain the batteries when you aren't using the boat as this helps with prolonging the battery lifespan

Where are the battery draining adapters you mention?

I can't seem to find them on their website.

Recently brought and used my bait boat but won't be using it for another 5-6 months now, so need to look after those batteries.

Not questioning you as i know this is what boatman recommend, but...
Is this actually necessary to do?
I can't think of any other battery powered device I've actually done this for, ever.

Should batteries not have a standard life span anyway, without having drain and charge to keep them in good condition?

Most devices are now lithium ion and the boatman batteries are lithium phosphate.

Very intersting topic as a new owner of a vulcan I was struggling a bit with this concept too. A quick google check on lithium ion v lithium phosphate suggests the latter are actually more suited to long term storage? I have zero knowledge on this topic I hasten to add, other than a quick internet search! Anyone that has owned one and not drained the batteries had issues?

AI response:

"No, you should not fully drain a lithium phosphate battery; instead, keep it in a shallow discharge state (between 20% and 80% is ideal) to maximize its lifespan. Over-discharging can damage the battery, and while a battery management system (BMS) usually protects against complete discharge, letting it stay in a low-charge state for a long time is still harmful."

I'm not sure why Boatman suggests draining the battery, based on this.

I'm new owner too...
I'm going to do what boatman recommends only takes couple of hrs would of thought...
Come home from work then use the battery as a power pack to charge phone
Then recharge battery to full then store for a 3 mths then do the same again
Two nights doing this job done

No expert here, but for the Carplounge RT4 I have, it is not recommended to store the batteries fully charged for long periods. They recommended reducing the battery voltage should the boat not be used, for example, over the winter period.
Discharge does not mean to run the battery flat, but to discharge to around 50-60% of its fully charged voltage.

This might help:

Why is it important to storage charge lithium batteries?

Storage charging is charging your lithium battery to 60% voltage so you can leave it on the shelf for an extended period. Leaving your lithium batteries fully discharged or fully charged will cause the cells to deteriorate and get out of balance. This will cause your lithium battery to lose life cycles or even be rendered useless.

What voltage should you store your LiPos at?

You should store your LiPos at around 60% of the rated capacity or 3.8v per cell. For a 2s pack, that would be 7.6 total volts(2 cells at 3.8v per cell = 7.6v). An 8s pack would be 30.4 volts(8 x 3.8v = 30.4v).

What voltage should you store your Lithium-ion batteries at?

Similar to LiPo batteries, you should store your Li-ion batteries at around 60% of the rated capacity or 3.8v per cell. For example, a 4s or 4 cell battery should be stored at 15.2 volts (3.8v x 4 = 15.2v).

What voltage should you store your LiFePO4 batteries at?

You should store your LiFePO4 batteries at around 60% of the rated capacity or 3.2v per cell. Store your 6 cell (6S) LiFePO4 battery at 19.2v (3.2v per cell x 6 cells = 19.2v).

What is the storage function on my charger?

The storage function on your charger will charge or discharge your battery to the proper storage voltage for you, depending on its current voltage. If you plan to leave your battery on the shelf, plug it into your charger and select the storage function before leaving it on the shelf.

How often should I cycle my lithium battery?

For the best performance and to maximize cycle life, you should use or cycle your lithium batteries once per month. When cycling, perform a full charge and a full discharge cycle. Then charge it back to storage voltage and you're good to go for another month. This process is essential to prolonging the life of your lithium batteries, keeping them from getting out of balance and becoming dangerous, and will definitely pay off in the long run.

Seems to be the best explanation i have seen.
Thanks for that 👍

I think people get confused by being told to discharge the battery and assume it needs to be flat.

Didn't want to start a new thread, but wondered how people ar getting on with their V2 Vulcans.
I'm considering the GPS model as I already have a Deeper, any advice re mounting the arm on the back? If it's not in the centre does it make the boat more difficult to steer? Can it be attached to the rear door without interfering with the line if taking out a rig? Any other useful info before I fork out?
Cheers all..

If you want a mount look at GS tackle. He has just brought out a front mount for it so nothing gets in the way.
Are you sure?

This action cannot be undone.

Yes, continue
