Lithium batteries & insurance

[Lovey80]

LifePo4 is definitely the safest mass produced battery but there is still a thermal runaway risk if there’s a short or a serious overcharge for a long period of time.

If safety is the ultimate goal then Lithium Titanate Oxide (LTO) cells are the supposed to be the safest with zero thermal runaway and cold temperature charging. they’re also excellent at fast charging and discharging. The only problem with LTO is the price and the density is much lower than LifePo4. If they can find a way to match LifePo4 in density and cost to produce then I think LTO would get regulated and the others would nearly be regulated out of existence. Enough Tesla fires already.

Probably makes sense to not leave the battery connected to a running charger .

Charges & BMS can malfunction .

Why would that be?

Why would that be?

If the battery charger of BMS fails .

I have had a CTEK fail & fry an AGM previously - kept pumping in full 25amps ...... so it can happen

Now just imagine your outboard regulator shits itself 10 minutes into a 1 hour trip and is pumping in (Insert ridiculous voltage here) instead of 14.4. -15v. Much higher chance of that happening bouncing around on the ocean over 500 hours than a CTEK going berserk at home on the chargers..

C-Tek chargers are popular but not fail proof....have replaced two that have either fried batteries or themselves.
I won't buy C-Tek again.

I currently have faith in the Victron charge systems.....when I swap to lithium it will be with Victron again.

Professionally installed does not mean much.....any auto electrician could install.....whether he uses good components hooked up the safest way is yet to be proven.
Is there a specific course auto elecs would have to do to get accredited for LiFePO4 systems?
I assume not seeing none of them allude to specific accreditation.

I think the CTEK chargers were good in their day ( early smart chargers) but they do fail - like mine did & I know of a couple of others that have failed as well .

I went to the Victron chargers (2 x 12/25 bluesmart) a few years back ...... been great & these are permanently wired in .
