LiTime 300Ah 12V LiFePO4 Battery Review (2026): Max Single-Battery Capacity

The LiTime 300Ah is the value brand’s biggest single 12V battery, and unlike the 200Ah it comes with the high-output BMS as standard. For full-time rigs and larger off-grid loads it consolidates a lot of capacity and power into one case, and this review covers whether that consolidation is right for you.
Quick verdict
The LiTime 300Ah stores 3,840 Wh and ships with a 200A BMS as standard, supporting about a 2,560W load from one battery. It is the value pick for full-time and high-capacity 12V builds. At roughly 63 lb it is heavy, and it is only the right size if you genuinely need that much energy.
Specs at a glance
| Spec | LiTime 300Ah |
|---|---|
| Capacity | 300Ah / 3,840 Wh (12.8V) |
| Continuous discharge | 200A (standard) |
| Max output | ~2,560W |
| Weight | ~62.8 lb |
| Warranty | 5-year |
Specs are manufacturer-stated. The 200A BMS comes standard here, unlike the 200Ah where it is a Plus-only feature.
What it does well
The LiTime 300Ah gives you the most single-battery 12V capacity in the value lineup — 3,840 Wh, enough for two to three days of a full-timer’s consumption without sun. And because the 200A BMS is standard, it runs a 2,000W inverter from one battery without paralleling, which is a real simplification for a big build. You get LiTime’s strong cycle-life ratings and 5-year warranty, and consolidating three 100Ah batteries’ worth of capacity into one case cuts down on interconnects and fusing.
Where it is limited
Weight is the headline cost: at about 63 lb it is a serious lift and needs a secure mount, which can matter for trailer tongue weight or van payload. Concentrating all your capacity in one battery also means a single point of failure — if it goes down, your whole bank does, where three separate batteries would leave you partly running.
And it is simply more battery than many rigs need. If your daily use is modest, paying for 3,840 Wh you rarely touch is wasteful — size against real consumption using 100Ah vs 200Ah vs 300Ah. Above this capacity, a 24V or 48V system often makes more sense than stacking 12V batteries, for the wiring reasons in watts vs volts vs amps.
Best for, and skip if
Best for: full-time RVers and larger off-grid 12V builds needing maximum single-battery capacity and 200A output at a value price.
Skip if: your daily use is modest (a 200Ah or 100Ah will do), the weight is a problem, or you are scaling large enough to consider 24V/48V instead of stacking 12V.
How it compares
Against the LiTime 200Ah, the 300Ah adds 50% more energy and includes the 200A BMS standard, at 14 lb more weight. Against the SOK 206Ah, LiTime offers more capacity for less money but without the heater or serviceability. See the field in the buyer’s guide.

Frequently asked questions
Does the 300Ah run a 2,000W inverter?
Yes — its 200A BMS is standard and supports about a 2,560W load, so a single battery runs a 2,000W inverter without paralleling. This is a key advantage over the standard 200Ah, whose 100A BMS cannot.
Is one 300Ah better than three 100Ah batteries?
One 300Ah simplifies wiring and delivers 200A in a single unit, but concentrates weight and creates a single point of failure. Three 100Ah units give redundancy and easier handling. For a clean high-output build, the single 300Ah is tidier.
Should I go 12V 300Ah or move to 24V/48V?
Around this capacity the question is worth asking. Higher-voltage systems cut current and cable cost for large loads. If you are scaling well beyond 300Ah or running big inverters, 24V or 48V often makes more sense than stacking 12V batteries.
How much does it weigh?
About 63 lb — a two-person lift in practice and needing a secure mount. Factor it into trailer tongue weight or van payload, since it is roughly the weight of three 100Ah batteries in one case.
