Sorry for the delay but thank you guys for all the advice. It rained Sunday and I've been working all week so haven't been able to get back out there to check for lose connection or measure with the multi-meter. I did run the load again and used my victron shunt to verify what the BMS was...

Hey guys I have three cells with what I consider minor damage. Two look like it's very superficial one has a good dent on the edge. What do you think? Still usable or do I need to order more?

I've searched for this specific question without luck. I have the power supply set to 3.65v and the CC is maxed out (10amps). However the voltage on the power supply is staying at 3.60 and the amps are going from 0.00 to 0.24 and anywhere in between. The cells are testing at 3.644-3.641 each...

I'm a complete noob here but I've followed the top balancing tutorial download from here, watched Will's video and read the power supply owners manual and I still cannot figure out if this is right or wrong. I turned on the charger, turned CC all the way up, turned CV knobs to set it to 3.60...

They are eve 105ah cells. I put 16 in series.

I know it came with the switch and I have the display with a button the side of it too.

Where did they make you send the old battery to?

Thank you for your replies. Do you know why the power supply was only showing 3.60 vs 3.64?

Last year I purchased a 24’ electric pontoon boat (Torqeedo 4.0 – 48V) and converted it from being charged with an extension cord/ProMarine chargers to being charged by 440W of solar through a Victron 100/20 MPPT. The boat was set up with 4x12V SLA Everstart 100AH batteries. There were already...

Here's my SCC settings..

Did you ever figure this part out? I'm also planning on having the battery just connected to a victron solar controller and need to know that it will charge to 100%

Yup when it's charging I see 16/17amp like this. I can get it charging it again by unplugging the charger waiting two minutes for the chargers soc light to go out and plugging it back in.

How come? It's only showing 3.400

Just to be clear I don't currently have lithium I have SLAs.

I have two systems on my boat 48V and 12V. I just upgraded from SLA to DIY Lifepo4's. I used a JK BMS for both the 48V and 12V. I have a Victon Dc-Dc Converter 48/12 - 9 that I used to charge the 12V off the 48V SLA's. Since putting in the Lifepo4 however I've noticed the 12V does not seem to be...

I also have the Victron BMS on their so I can do another test tomorrow and compare the two (shunt vs bms). What else should I check with the multimeter?

I was watching a tear down of an epoch and liked how they had temperature sensors going to the terminals as well as the cells. But do any of the BMS's we can get have this ability?

Does anyone have experience with these eco-worthy hyesn lifepros? They have Bluetooth, heating and low temp cut off. https://a.co/d/2LKJwDw

I'm getting ready to switch my electric boat from SLA to Lithium. The system is 48V and the SLA had 100AH. But as we all know with SLA you only use 50% capacity. This got me thinking since Lithium can go to 80% do I still need 100AH or can I save a lot by going with 50AH? I also have 440W of...

Noob question. But the dc power supply I bought to top balance my cells has this plate going from negative to ground. Is it needed?

The battery is a 48V using 16x 100AH EVE cells and a JK BMS. I built the batter back in March and it's worked great all year till now. Yesterday I noticied that anytime I put a load of 2,000W or more on the battery cell number 7 goes from the same as the rest to a lot lower and fast. The wire...

https://www.aliexpress.com/item/1005004126778839.html Is there a US vendor I can find this box at or something similar? Thank you!

Thank you. All those setting are initially what happened when I turned the bms on and set it to lifepo4. I've changed to the setting you recommended. But as of right now the charger stopped charging and I'm not sure why

Great question. I'm going to redo its connection and see if that changes anything.

We just finished our first battery and the BMS was at 70% which sounds right as we hadn't charged them yet. When I started charging within seconds the BMS showed 100%. Anyone know why this jump occurred? It's obviously not at 100% as you can see from the pictures the cells are still at 3.3/3.4.

Fixed #10 and now it's reading same as others but the charger still is not getting any of them to 3.6

I've been talking with customer support but I'm not getting anywhere. There are two light power boats being sold. One has 5 wires and one had 7 wires. Does anyone know which is the newest and the difference between them...

I can certainly do a top balance but I did that when I built the battery and thought the JK with active balancing would make it so I never had to again. But they were at 100% SOC for these test.

I was getting ready to order some EVE 105s and ran across some CALBs. They don't look like older CALBs with the plastic case. These look just like the EVE blue cells. Anyone have experience with these? Should I stick with the eve's? Thank you!!
