Which 100Ah Lifepo4 battery should I buy?
I would use it to power my boat motor (Rhino BLX 70). There are tons of different ones out there, and the price ranges from €250 to over €1,000. It's important to me that it's durable, splash-proof, and, most importantly, has an accurate charging indicator. Be it via an app or a digital display on the battery. I'd prefer something under €400. And while we're at it, which charger would you recommend?
Hope for answers °°>

In principle, I recommend that you take a AGM lithium battery. They are well suited for use on boats as they are leak-proof – “maintenance-free”. I recently purchased an AGM battery here (although smaller): https://greencell.global/de/lifepo4-akkus/4098-green-cell-lifepo4-akku-128v-100ah-1280wh-lfp-lithium battery-12v-mit-bms-fuer-reisemobil-solarbatterie-wohnmobil-offgrid.html Costs a lot, but this is the case with the sizes. Of course, you can also take cheaper standard car batteries, but you will not be happy because they are not designed for continuous load (the power breaks in) and if the acid runs out you can hardly load the environment and get powerful trouble.
I would keep a charge level indicator externally and not on the battery. First of all, a battery doesn’t last forever – you’ll have to replace it sometime as they take advantage of it. Secondly, the additional costs for the installed charge display are disproportionately higher.
What kind of charger are you planning? For land with 230V at the outlet? The CTek chargers are then available.
But thanks for which you have linked is a Lifepo4 battery and not an Agm… and what do you think of this one? https://de.renogy.com/12-v-100-ah-lithium-lifepo4-akku-mit-bluetooth/
Uh, sorry, I meant either a AGM or a LiFePo4. I didn’t say it clearly.
I don’t know what I think of the linked one. She’s very cheap, but that makes me a little stubborn. It is simply important for batteries for boats that they have to deliver constant power and not like starter batteries for a short time. I think you’ll probably get along with the linked one. The Bluetooth is a nice gimic that the acquisition of a power meter will take you off first, but I wouldn’t fix the purchase of a battery.
I really don’t know. The problem is that if I take myself 600€ in hand, it is a lucky game whether the battery is good or bad… There are variations everywhere and have now spent 15h researching it and still do not come to any result
