The full buying guide: lithium vs AGM, and our top picks with direct price links.
Sticker price vs lifetime cost, weight, cycle life, and cold-weather truth — with a calculator.
Add up your loads, pick usable capacity, and avoid the #1 mistake beginners make.
A practical look at the 100Ah Bluetooth and UL9540A models — capacity, app, build quality.
Head-to-head on price, app, certification, and real RV use — plus which one we'd buy.
Compare runtime, weight and price across the three most popular capacities — and who each one actually suits.
Per-cell voltage, state of charge and temperature from your phone — plus whether you still need a shunt.
The converter, cabling and fusing costs nobody budgets for — plus the cost-per-cycle math that settles lithium vs AGM.
How long LiFePO4 and AGM really last, what shortens life early, and the clear signs it's time to replace.
Shore power, solar, and alternator charging — plus the charger profiles and DC-DC chargers you need.
Store LiFePO4 and AGM over the off-season without killing them: the right SoC, temperature, and check-up schedule.
The 12V LiFePO4 voltage-to-state-of-charge chart, plus why resting voltage beats loaded voltage.
The watts-to-Ah formula, MPPT vs PWM, and how many panels your lithium or AGM bank actually needs.
When a 24V system beats 12V for large banks, big inverters, and long wire runs — and when to stay 12V.
