12V 100AH Lithium Battery for RV

FAQ

Q1: How does the warranty work? whow will provide a new battery in the event of a failure? the weize store doesn't seem to by weize?

A1: The pamphlet that comes with (100ah) states there's a 5 year warranty. The description here states 10 yr. Seeing as this is a low budget China special, don't expect a warranty

Q2: Can i use a 12v smart charger (2/4/8 amp)? it says it can charge agm or wet or gel, i don't see lithium ion on there, but this is fairly new charger

A2:

No no and NO! Don't listen to people who know NOTHING about lithium batteries and say things like "a low amp charge will be fine." I build 18650 battery packs and use Lipo (Lithium Polymer) packs extensively in our hobby. The Peak voltage is 14.8 for a liFePO4 battery, and lithium does NOT like a "float charge" it will destroy them. Thankfully when you see BMS they include a charge management system built into the battery so Mr "It'll be fiiiine" and "Slow charge won't hurt it" don't burn their garage to the ground.

The only saving grace is IF they include some kind of voltage boost circuit in the built in BMS that raises the input voltage sufficiently...but I doubt it. The battery would be pretty expensive with a built in charge circuit instead of a built in protection circuit. see less

Q3: My mobility scooter has two 12v 18ah agm batteries in series. will two weize lifepo4 12v 20ah batteries be compatible?

A3: If they fit where the old ones go then yes they are compatible. The Weize batteries are the same voltage so there’s no problem but you can’t charge lithium batteries with the AGM charger. You need a charger that is made specifically for lithium batteries.

Q4: Can these be used with a wing generator?

A4: Yes but you will need a Battery Charge Controller (BCC) with the same voltage (input) compatible with th output of your wing generator and BCC output matched voltage of the battery or battery bank. These are 12Vdc batteries for a single battery or multiple batteries in wired in parallel. You might also add multiple batteries in ‘series,’ where 2 batteries would give you 24Vdc or 3 = 36Vdc and so on. Some charge controllers also incorporate an inverter to provide 120Vac or you can use a separate inverter if you even need or want 120Vac in addition to the dc voltage.
