Recommendations for replacing our two gopower LifeP04 batteries 100

[oldwave]

I’ve always tried to give reasoned and thoughtful advice to questions. There are various personalities in any forum. Your choice to participate or not is just that. The price is right.

Just a comment

I am new to this forum and to Escape-pick up an E23 in 2 weeks. I have found some valuable information here but am quickly tiring of the finger wagging, chest puffing, mansplaining and inane comments I keep seeing. I for one do not care who is smarter, has more experience and generally knows better. I find all comments and ideas to have some value and are worth considering. Sorting through the BS causes me to close a discussion thread before I am done with it and most likely miss some valuable ideas. I hope this is merely a temporary condition and not a sign of the way things are.

Just be patient and wade through it. Different folks have different ways of expressing themselves and most of these people have been exchanging ideas for many years. Some may be a bit more exuberant than others in their expression. If it seems argumentative its a friendly disagreement between friends.

Wow, those are quite the introductions!

Many people find these forums helpful, informative and friendly. If you don't there is no need to participate. Everyone is different.

Personally I find all the different views and experiences invaluable even if they are off-topic sometimes (which yours are in this thread BTW). Yes, people and their personalities come through but it's easy to disregard or skip their posts if they don't appeal to you. On some forums there is a feature to block posts by certain members. I never use that feature so I don't know if it is available here or not. That's something you could try.

no thanks, not when you can buy 300AH batteries with heaters and bluetooth management for $1100, https://www.currentconnected.com/pr...d-bluetooth-lifepo4-battery-epoch-essentials/

For me, I'd rather have a system I can easily work on myself, have flexibility in form factor and not be at the whim of failed warranty promises, battery companies going out of business, etc. Yes, there certainly are cheaper/less expensive options.

Any luck on getting the batts to charge to a higher voltage OP?

Not too denigrate your building your own, but these batteries can put out lethal voltages if there’s a mistake. Not every one has the knowledge and skill to construct one safely. I’m sure I could do it, I worked on lot as of tech design and low voltage systems. I just rather not. I recently upgraded my battery to one 330 amp hour Victron battery . Expensive yes. Cheaper than a 230 amp hour Battleborn by 500. Superior bms system (its external).

no 12V system can possibly generate a lethal voltage, or even enough voltage for a slight shock. yes, it can output enough current into a short circuit to arc weld, or light a fire. too much current can cause a lithium cell to swell or possibly even explode (but Lithium Iron Phosphate aren't nearly as likely to explode than conventional Lithium Ion). I have zero interest in building my own batteries because I can buy excellent well made well packaged batteries for a good price, such as the metal cased SOK I used on my build 2.5 years ago. 412 AH total, 5260 watt*hours. Today, the improved version of these with the heater and internal bluetooth monitoring is half the price I paid in jan 2022.

Not quite as cheap, compact, or as light weight as some of the DIY options, but that's still a pretty good battery for the money. I'd be curious is the BMS has a built in balancing feature, as they don't mention it in the description.

Hey OP, any luck?

my 206AH SOK batteries certainly auto balance when they are full charged. I have graphs from my Victron Smartshunt showing it happening.

here's the last 1 hour 25 min of a 50A charge cycle (blue is Amps, orange is Voltage... the jiggle in the amps is the DC fridge cycling).. The spikes after the Volts hits 14.4 are the BMS eq cycles.

and wow, I paid $1200 each for these 2.5 years ago, they are $650 now for the updated version with a heater and bluetooth battery monitor.
