Title: Charges my 48V golf cart fast and reliably
Got this with my LiThink 48V 105Ah golf cart battery. It charges from 30% to full in about 3 hours—perfect for plugging in after a round and being ready for the next day. The build quality is impressive, heavy duty cables and a nice carry handle. The fan is audible but not annoying, and it only runs when needed. I've been using it for 3 months now, charges consistently every time. The connector fits snugly into the cart's charging port. No issues with overheating or cutting out early. If you're converting your cart to lithium, get the matching charger—it's tuned correctly for LiFePO4 and will extend your battery's life.
Bought this to go with my LiThink 36V 50Ah TM battery. Charges from 30% to full in about 2.5 hours—fast enough that I can recharge between morning and afternoon trips if needed. The unit is compact and well-built, aluminum case feels premium. Has a cooling fan that kicks on when needed but it's pretty quiet. The connector is solid and clicks in securely. I like that it has indicator lights for charging status. No complaints at all. If you're running a 36V system, this is the charger you want.
Needed a faster charger for my 100Ah trolling battery after getting tired of waiting 10 hours. This 20A unit cuts my charge time to under 3 hours from 20% to full. The waterproof housing is no joke—I mounted it in my boat's stern compartment and it's been soaked multiple times, still working perfectly. The charging algorithm seems smart, starts high then tapers off as it approaches full. My battery doesn't get hot during charging. Also have the 10A version for my smaller battery, both are great. If you have 100Ah or larger, get the 20A, you won't regret the faster charging.
Bought this for my 12V 50Ah trolling motor battery. It's fully waterproof—I mounted it right in the battery compartment of my jon boat and it's survived rain and splashes without issue. Charges my 50Ah from dead to full in about 5 hours, perfect for overnight charging after a day on the water. The unit stays cool during operation, no overheating like some cheap chargers I've tried. Cables are heavy duty and long enough to reach. Simple, reliable, does exactly what it's supposed to do. Great for smaller batteries or as a maintenance charger.
Replaced my EZGO's four 12V batteries with this 48V 105Ah metal case version. Fit perfectly without modifying the battery compartment—just dropped it in. The metal case feels super durable, way more solid than plastic. Real-time monitoring display (sold separately) shows SOC, voltage, current. I play 36 holes a week and charge maybe once every 2-3 weeks now. The 200A BMS handles hills and loaded cart without breaking a sweat. My neighbor with a new lithium cart paid twice what I paid for this. Incredible value.
My 2008 Club Car had six 8V lead acid batteries weighing about 30lbs each. Swapped to this single LiThink 48V 105Ah at 87lbs total. Had to make a couple minor modifications to the battery tray (cut some plastic spacers, added a plywood base) but nothing crazy. The performance difference is unreal—faster acceleration, maintains speed up hills, and I drove it around the neighborhood for 5 days before needing to charge. No more watering batteries or cleaning corrosion off the frame. Best upgrade I've made to the cart.
Paired this with my Minn Kota Ultertra 80lb thrust. Fished 8 hours in tidal current, spot lock engaged probably half the time. Got home and the app showed 64% remaining. The weight savings is insane—I can actually lift this battery with one hand. Charged up fast with the LiThink 43.8V charger (about 2.5 hours). Build quality looks great, terminals are solid. If you're still running lead acid on your 36V trolling motor, stop suffering and buy this.
I was running three 12V AGMs in series for my 36V trolling motor—total weight 215lbs. Switched to this single LiThink 36V 50Ah at 33lbs. That's not a typo. My boat's draft is noticeably shallower and hole shot improved. Used it for two trips totaling 12 hours of run time, battery was at 51% when I finally charged it. My old AGMs needed charging after 6 hours. The Bluetooth works great, shows me everything I need. This is a no-brainer upgrade for anyone with a 36V system.
I built an overland camper setup and needed max capacity in minimal space. The 334Ah Mini Pro fit exactly where I had my old 100Ah lead acid. I've run a 12V fridge, diesel heater (all night for 3 nights), lights, phone chargers, and a small inverter for laptop. After 3 days off-grid, battery was at 51%. The Bluetooth app shows everything clearly—voltage, current, cycles, temperature. The self-heating feature is a bonus for winter camping. Expensive? Yes. Worth it? Absolutely.

Upgraded from a 100Ah to this 165Ah TM because my Livescope and dual graphs were killing my runtime. Night and day difference. Fished a weekend tournament, two full days on the water, didn't charge between days. End of day two still had 42% left. The weight is still way less than my old lead acid setup. Bluetooth monitoring is seamless, connects every time. Also love the low-temp protection for early spring fishing. LiThink hit it out of the park.
Bought two of these to run in parallel for my 24V system. Ran them hard for two full days on a bass trip—first day 8 hours, second day 7 hours, lots of heavy current and spot lock. Checked Bluetooth after the second day, both batteries at 63% and 67%. I was blown away. My old setup would've needed charged after the first day. The app is intuitive, gives you everything you need without clutter. Absolutely worth every penny.
Trolling motor beast in a small package
Bought this for my 14' aluminum with a 55lb outboard. First trip out I ran it for 7 hours straight, mostly half to full throttle. Battery was at 61% when I pulled the boat out. Charged fully in about 3 hours with the 20A charger. The fact that I can monitor everything from my phone gives me so much peace of mind. No more wondering if I'll make it back to the ramp. Great value for the price.
Had two heavy lead acid batteries in my jon boat taking up half my storage. Swapped to this single LiThink Group24 and saved over 50lbs. The 100Ah runs my trolling motor and fish finder all day easily. Used it for 8 hours on the river fighting current and still had 65% battery. Bluetooth lets me check from my phone while fishing. Build quality seems solid. Will buy another for my buddy's boat.
I installed four 334Ah Mini batteries in my truck camper to build a 24V system. I drove through Alaska and the Arctic Circle, and the road conditions were absolutely terrible, with the batteries bouncing around in the rear compartment the whole way, but they performed flawlessly. The tested capacity of each battery was actually higher than the rated value, so I really can’t say enough about the quality.
The battery compartment in my travel trailer was originally very small, and many high-capacity lithium batteries simply wouldn’t fit. This 334Ah Mini fit perfectly, and it’s about 30% smaller than a typical 300Ah battery. The self-heating function is especially useful in winter—it can still charge even when the temperature is a few degrees below freezing, so I don’t have to remove the battery and bring it home.
I switched to a 334Ah Mini for my Class C RV, replacing the original two 6V lead-acid batteries. My old lead-acid setup could only last about 14 hours, but now with the same power usage habits, two full days and nights are no problem. What I like most is the Bluetooth app—I can check the battery level while lying inside the RV without having to go outside and lift the seat.
The biggest difference I noticed the first time I used lithium for trolling wasn’t just the runtime, although the runtime is definitely much longer. It was the stability. The power stayed consistent from start to finish, and it ran exactly as fast as I wanted the whole time. The TM model is clearly designed for this kind of use, and it performs flawlessly.
I’ve been using my TM battery for almost a year now without a single issue. I mainly use it on inland lakes and occasionally in saltwater. The terminals show no signs of corrosion, the casing is solid, and the build quality is excellent.
I installed it on my kayak, and I was initially worried that 165Ah might be too heavy, but it turned out to be no problem at all. I ran my trolling motor and fish finder with it, played on the water for 6 hours, and still had more than 80% battery left when I got home. I only regret not switching to lithium sooner.
I connected two TM batteries in series to make a 24V setup for my 80 lb Minn Kota. I used to run two lead-acid batteries in series, and together they weighed nearly 60 kg. Now these two together weigh just over 25 kg. After a full day fishing in fast current, I still had more than 80% battery left when I got home. A friend saw it and ordered the same setup too.
