Lithium batteries have become the standard for powering sonar on kayaks and boats and on the ice as well as powering trolling motors. However, these batteries require specific chargers that are different from traditional sealed lead acid batteries.
Recommended chargers:
- 5, 10, or 20 amp Rebel batteries chargers (under All Products): www.rebelbatteries.com?afmc=1d
- 10 amp charger with alligator clips amzn.to/33kN4iR
- 3 amp Dakota lithium charger amzn.to/3nq5plA

Purchased an Amped Outdoors 100Ah Lithium Battery. The battery comes with its own charger. Definitely a game saver !!! Great video
Thanks Tyler, I was waiting for this one.
Tyler, I use those same connectors but I have both the Anderson connectors and the clip style on the battery charger leads
Thank you very much for your recommendation, Tyler !
I have a 12 volt diesel tank with a 10GPM pump. It states 12 Volt 10 amp. I only use it 5 minutes a month. I assume a 10 amp lithium battery would technically run it about 50 minutes before getting a low voltage?
Hey Tyler. You should update the link for the 10amp charger. That product is discontinued. It was easy enough for me to find the new version but you might want the appropriate link.
I wouldnt mind spending more money to get faster charging but will that lead to tripping breakers for the outlets? I dont want to pay for a charger that my home wiring cant handle.
I need a good 100 amp charger for a 30 kw 24 volt battery i built. It normally charges from my victron solar equipment but sometimes it would be nice to just plug into the house and charge with something more than the 40 amps that my house plug charger does. Maybe i just need a few of the 40 amp chargers but youd think theyd make something larger for the big batteries
What brand 40 amp charger do you use? Are there any issues with tripping the breaker on you home's outlet circuit?
@@stevenichols4060 I use a power max 50 amp charger that only actually pushes about 40 to 46 amps. It's never tripped a breaker unless I had something else on the same circuit. I also have a 3000 watt powmr inverter that has a super nice 40 amp ac charger built in and it's adjustable from 5 amps up to 40 amps and you can adjust the voltage from I'm thinking like 22 volts up to 30 volts but I never charge to higher than 29.2 and normally only charge to about 28 volts. If I use both chargers at once I can charge from AC at about 85 amps but they definitely gotta be plugged into separate outlets. The power max is cheaper and it's been a great way to charge when ive needed it and I'd highly recommend either charger. I have a DC to DC victron charger that I've used to link my leaf battery bank to my 30 kw of lifepo4 and the DC to DC charger is adjustable in every way imaginable. I set it so that if the lifepo4 get down to 22 volts the DC to DC automatically turns on and dumps all the leaf battery into the lifepo4 bank. I hated seeing the leaf pack sitting not being used after building the lifepo4 so I made it part of my energy storage. I have 4 victron charge controllers for my solar and a couple spare powmr on the shelf but once I started using victron I doubt the powmr cc will be used although they were actually great also but the monitoring with my phone is better with the victron. I'm still using the 4000 watt low frequency splitphase sungold inverter as well. I'm no solar expert but I do love it so if you need any advice I'd be glad to help
A few questions: 1) Since you're not supposed to leave a LiFePo4 battery on a charger after it's 100% charged, do the Lithium specific chargers automatically shut off when fully charged or do you need to monitor it? 2) Do the Lithium chargers you recommend indicate the charge level when you connect them? Otherwise, do you have to buy something separate to verify the actual charge level? 3) what's the best way to reduce the charge to 70% before storing? 4) I'm planning to keep my LiFePo4 battery (20AH) in a standard battery box along with a PWM. Would you recommend putting a small fan in for ventilation? 5) Is there a cheap charge indicator you can leave on your boat/kayak set-up? I'd like something I can view from the seat of my kayak but that's not connected to the motor or battery box. Thank.
1.) Is not true. Almost all modern lithium batteries have a BMS system that prevents over charge and damage to the battery.
2.) None of the chargers show the charge levels, although on the larger Bluetooth capable batteries you can simply use the app to check them.
3.) Reducing to 70% is easy. Just drain the battery using something that has a known amp draw and draw it down 30%
4.) No fan is necessary unless storing in direct sun light
5.) There are some products available ampedoutdoors.com/products/bluetooth-smart-capacity-meter
@@spiltmilt thanks.
Perfect timing…thank you much!
Thanks for the video. I just recently bought 2 12v 10ah lithium batteries. Do I need to charge them out of the box - or do they come precharged?
Typically shipped at 80% charge
@@spiltmilt Thanks!
It seems to be a recommendation not to overcharge them. My charger has a red/green light to indicate when they are charged. With this setup how do I avoid/know when to turn it off to avoid overcharging?
Your charger will automatically shut off when charged as should the BMS
@@spiltmilt Thanks!

when charging your batteries, do you put them in a firesafe box or bag?
No
What brand battery do you use for your trolling motor?
The Aolithium 100 ah battery with built in bluetooth. This allows you to connect to your battery using an app and see real time use and charge remaining amzn.to/3nRXssD
what about the minn kota 315D , its supposed to charge either type
miller tech battery rep told me that if I buy a minn kota on board charger make sure I get a minn kota with PCL NOT just a pc.. I'm buying a 2 bank mk 220 pcl
do you need your charger up all the time or unhooh it when fully charged?
You can take it off the charger when its charged
Is the battle born better than this battery ?? When feature doesn’t have the Bluetooth
No it doesn't have Bluetooth and is too expensive IMO
I purchased a reBel 50 Ah battery for my first trolling motor. Unfortunately reBel might be out of business. Entire inventory soldout & no reply of email i sent on July 22nd. Battery charger just started acting up after only 4 months use. Looks like i am going RoyPow ( Battery Teardown via William Prowse ). Just got my first fish finder so needed another battery. I usually fish for around 5 hours ...... and use full throttle a lot to get to my destination. RoyPow has a 30 Ah model for only $160. This will power Fish Finder & give me some extra energy reserve for trolling motor.
RoyPow (10 amp ) charger would work fine for my reBel ?
As long as it is designed for lithium should not be an issue. I’ve had a few chargers fail on me but no batteries aside from Dakota
What a Dakota battery failed my God at the price they charge for them 😏
How low should the battery for Lifepo4, fall before recharging? It will be used on a wheelchair. Thank you!How low should the battery for Lifepo4, fall before recharging? It will be used on a wheelchair. Thank you!
You can draw lithium down to between 5 & 10% before it needs recharging
Is it better for the battery if I set it up to charge up to 90% via the BMS which has a bluetooth or leave it to charge to 100%? It will be used every day. @@spiltmilt
I bought a brand new 12V 100ah lithium ion battery from a friend who says he never used and it's at eighty percent. I'm probably not going to use the battery for the next 6 or 7 months for the off season for me. Is that ok to store the battery at eighty percent or do I need to reduce the percent and how? Also, the battery didn't come with terminals.You have a link for 8M terminals?
are you pluging it into a regular outlet
Yes
Try these, Victron Energy Smart Battery Sense
Hey Tyler. I bought the ampere battery charger off Amazon. First time charging my Aolithium battery. The battery charger light stayed red even when the battery was reading 100 percent charged on the app. I’ve read don’t overcharge so I pulled it off the charger. But the light wasn’t green. Any insight on this? Thank you
What battery charger are you using? Also no way to “overcharge” these batteries as the BMS will prevent that from occurring
Ampere time battery charger. 10amp. The light just stayed red was hoping it turned green. But I left the battery on the charger for like 1/2 hour after it was 100 percent charged. Light was still red when I took it off
I've never monitored mine to see how quickly it flips from red to green after hitting a full charge. Have you cycled your battery at all or is it brand new?
This is a brand new battery. First charge for me.
That sometimes happens on an uncycled battery. It should start working after you cycling it a couple times.
i guess what i meant to say is will it hurt battery if its charging all the time. Thanks
No
What about charger &power supplier cobined for power outages on solar generator?
Can I use my 100 watt solar pannel to charge a lithium battery? Oh great information thank you
Yes you can!
