If you’ve been working with lithium-ion batteries for anything from powering small industrial equipment to maintaining off-grid solar setups, you’ve probably run into the 10 Series Battery. As a supplier who’s been bringing these batteries to customers across North America and Europe for the past seven years, I can’t tell you how many times I’ve gotten the same question from field engineers, inventory managers, and DIY solar enthusiasts: “What are the actual dimensions of the 10 Series Battery?” 10 Series Battery
It’s not a trivial question, either. I’ve seen projects derailed because someone ordered a battery that fit the label dimensions but not the tight space under their RV’s bench, or because a replacement battery for a pallet jack was 10mm too wide to slide into the existing rack. That’s why over the years, I’ve prioritized making our 10 Series specs not just accurate, but usable—no fine print, no vague “approximate” labels that leave you guessing. Let’s break this down, straight from someone who handles these batteries every single day.
First, let’s get one thing straight: when I refer to the 10 Series Battery, I’m talking about our standard, general-purpose model designed for 12V, 24V, and 48V system builds, which is the workhorse of our line. There are specialty versions—like the high-temperature model for mining sites or the slim-line for marine installations—but for this blog, we’re sticking to the core line that 90% of our customers order. That clarity matters, because dimensions change if you’re dealing with a custom variant, and I never want to confuse someone who’s just looking for the standard part.
Let’s start with the three primary dimensions: length, width, and height. These aren’t just numbers on a spec sheet—they’re measured on the actual packaged battery, including the plastic casing, the metal mounting lugs on top, and the terminals. I’ve had quality control teams double and triple these measurements because even a 5mm difference can mean the difference between a seamless install and a week of modifying shelves. For our standard 10 Series Battery, the measurements are exactly 330 millimeters (12.99 inches) in length, 170 millimeters (6.69 inches) in width, and 215 millimeters (8.46 inches) in height. That’s the base model. But wait—there’s a critical add-on here that most suppliers forget: the height measurement includes the integrated battery management system (BMS) cover on the top. If you thought you could shave that off for a custom fit, that’s not possible— the BMS is embedded, so the cover is a permanent part of the unit. I always advise customers to account for an extra 5 millimeters (0.2 inches) if they need to leave space for wiring above the battery, because the terminals stick up another 3mm above the BMS cover, and wires need room to bend without crimping.
Now, if you’re working with 24V or 48V systems, you might be putting multiple 10 Series Batteries in parallel. That’s where the next set of dimensions comes in: the terminal spacing and the overall footprint for multi-battery racks. The positive and negative terminals on each 10 Series are spaced 190 millimeters (7.48 inches) apart, center to center. For parallel setups, we designed the mounting lugs to line up perfectly with standard industrial battery rack slots that are 180mm apart from slot to slot. That means two 10 Series Batteries fit side by side in a standard rack without any custom modification. I’ve had customers who install four for a 48V off-grid system tell me this is one of their favorite features—no measuring, no cutting, just slot and connect.
But let’s talk about the edge cases, because those are the ones that come back to haunt you. For example, a few months ago, a customer in the RV industry ordered 20 10 Series Batteries for a fleet of camper vans. They initially assumed the dimensions were the same as a lead-acid battery, which they’d used before. Lead-acid 12V batteries are often around 310mm long, so they thought the 330mm 10 Series would stick out too far. Instead, they noticed something: the 10 Series has rounded corners on the casing, while lead-acid batteries are sharp-edged. That rounding actually made the total usable space in their van’s battery bay work out, because they could tuck the corners into the gaps they had. I always tell customers to look beyond the linear dimensions and check the contour of the casing—our 10 Series has a 2mm radius on all corners, which lets it fit into tight or irregular spaces that a blocky lead-acid unit can’t.
Another common question: do the dimensions change if you upgrade the battery’s capacity? We offer the 10 Series in three core capacities: 100Ah, 200Ah, and 300Ah, all for the same voltage range. You might think a 300Ah model would be longer or taller, but that’s not how we designed it. We kept the casing dimensions identical across all three capacities, so a 100Ah and a 300Ah 10 Series fit in the same space. The only difference is the internal cell configuration, which means the BMS and terminals stay in the same spot. That’s a huge win for customers who want to scale their system later—they can swap a 100Ah for a 300Ah without rearranging the rack or modifying the bay. I remember a customer who started with a 100Ah 10 Series for a small cabin, then added three 200Ah units a year later, and said it was the easiest upgrade he’d ever done because he didn’t have to redo his wiring or rack.
Let’s also cover the weight, because while not a dimension, it directly relates to how you’ll handle and install the battery. Our 100Ah 10 Series weighs 11.5 kilograms (25.35 pounds), the 200Ah is 22 kilograms (48.5 pounds), and the 300Ah is 32.5 kilograms (71.65 pounds). That’s a key point: the dimensions stay the same, but the weight increases with capacity, so if you’re planning to mount the battery on a wall or a shelf, you need to account for the weight of the highest-capacity unit you’ll use. I always include a weight recommendation in every order confirmation, because I’ve seen shelves bow under the weight of two 300Ah 10 Series Batteries that someone assumed would be the same weight as a smaller model.
Now, let’s get into how we arrived at these dimensions, because transparency matters to me. When we designed the 10 Series Battery back in 2017, we talked to 150 customers—from small business owners to large industrial operators—about their biggest pain points with battery installation. The top complaint was that off-the-shelf batteries were either too big for their space or had weird terminal spacing that made wiring a nightmare. So we set out to design a battery that fit standard industrial and recreational vehicle racks, used standard terminal sizes, and had dimensions that worked for 95% of common applications. We tested 12 different casing designs before landing on the current 330x170x215mm size. We also ran 500 drop tests to make sure the rounded corners could handle being bumped during shipping or installation, which is why that radius is a standard feature, not an afterthought.
I know that a lot of battery suppliers will hide behind “specifications are subject to change” or “contact us for exact dimensions,” but that’s not how I run my business. Every 10 Series Battery that leaves our warehouse has a label on the side that lists the exact dimensions, capacity, and terminal spacing—no fine print, no rounding up to the nearest centimeter. I even have a policy that if a customer measures a battery we shipped them and finds a discrepancy of more than 2mm, we’ll replace it for free, no questions asked. That’s how confident I am in these measurements.
Let’s wrap this up with a few actionable tips if you’re planning to install a 10 Series Battery. First, measure the space where the battery will go three times—once length, once width, once height—and leave a 10mm gap on each side for ventilation. Our BMS generates a small amount of heat, and like all lithium-ion batteries, it needs airflow to stay within its optimal temperature range (10 to 45 degrees Celsius). Second, if you’re putting multiple batteries in parallel, confirm the terminal spacing is 190mm center to center before you buy wiring—we sell pre-cut wiring for parallel builds that fits perfectly, but if you’re making your own, that measurement is non-negotiable. Third, if you’re working in a confined space, ask us for the slim-line variant, which is 15mm shorter in height (good for under-seat RV installs) but has the same length and width.
At the end of the day, the 10 Series Battery’s dimensions aren’t just numbers—they’re designed to make your life easier. I started in the battery industry as an installer, so I know how frustrating it is when a part doesn’t fit like it’s supposed to. That’s why I’ve spent years refining these specs, listening to customer feedback, and making sure every unit that leaves our warehouse matches what’s on the spec sheet.
If you’re ready to order 10 Series Batteries for your project, or if you have more questions about dimensions, capacity, or installation, don’t hesitate to reach out and talk through your needs. We work with everyone from single-cabin owners to large construction companies, and we’ll help you find the exact 10 Series model that fits your space and budget.
