Good price, solid battery

I was looking for a 12V 100Ah LiFePO4 Battery for my RV without breaking the bank. Got it during a flash sale. The discount made it a really good deal. Felt like I got great value for what I paid.

Reliable for my RV

I bought another 12V 200Ah LiFePO4 Battery from Wattcycle, my third purchase from them. The first two have been powering my RV for over a year now without any issues, so I decided to expand my bank. They've been consistent. No surprises with the order process or the product quality. The batteries always arrive well-packaged, and I appreciate that. It's why I keep coming back when I need more power for my setup. They just work, which is what you want with this kind of equipment. I've tried other brands in the past, but Wattcycle has proven to be the most reliable for my specific needs.

Love my new battery!

I got the Self-Heating LiFePO4 Battery for my camper, and it's fantastic! I used it last weekend, and it worked perfectly in the cold. It was easy to install, and the Bluetooth monitoring is super handy. I will definitely be recommending Wattcycle to my camping buddies. So happy with this purchase!

Decent battery, long shipping

I purchased a 48V 100Ah LiFePO4 Battery for my off-grid setup. The battery itself seems robust and performs as expected, holding a charge well for my solar panels. Installation was straightforward with the clear instructions. However, shipping took a bit longer than I anticipated; it was almost 10 days before it arrived, which held up my project for a few days. Customer service was responsive when I inquired about the delay, which was a plus. Overall, a good product, but they could probably improve on delivery times.

Thinking about getting a battery for my off-grid cabin. Anyone know how long these usually take to ship to, say, Texas? Also, is there usually a first-order discount or should I wait for a holiday sale?

E Emma F. 2 months ago
Shipping time really depends, I'm in Arizona and got mine in about 5 days. Texas might be similar. They usually have a first order discount if you sign up for emails, but sometimes the holiday sales like Black Friday are better, like 10% off site-wide or something.

Yeah, check for the email signup. I got like $50 off my 300Ah when I first ordered. Shipping was pretty quick for me too, maybe a week to Florida.

Hey, wondering if anyone's had issues with connecting these batteries? I'm looking at the 12V 100Ah ones for my RV and need to hook up a few in parallel. Is it straightforward or do I need special cables?

D David Kim 2 months ago
Nah, it's pretty easy. I got the 200Ah for my van last year and linked two in parallel with their cables. Just follow the instructions, they came with everything I needed.

Yeah, I think most of their batteries are designed for both series and parallel. Just make sure you get the right cables for what you're doing, they sell them separately sometimes but I think some bundles include them. Comes with a BMS too so that helps.
