ES R2480

US $907.77

CamperVan leisure battery storage can be any size, mostly by 12V, 24V and 48V in a battery pack. That is the fire-proof housing, longer lifespan LiFePO4 battery pack, and designated smart BMS(battery management system) to meet the power and energy requirement for all kinds of recreational vehicles(campervan off grid living). It is not just the 2 ~ 4 hours that people would like to stay in living room area with lights turn on, they need more options by whatever it can be under more energy and power. We value every vanlife style.

EL A1260

US $310.61

Lead acid replacement battery is much more important than it used to be, since the LiFePO4 is a much lighter, safer, better efficiency, quicker charging, 10 ~20 times more cycle life, and most importantly, they don’t need any maintenance at all. It is a LiFePO4 battery pack installed within a lead acid battery box – with alternative connectors, plugs or buttons, high quality PCB(printed circuit board) control and an easy-to-handle holder. EL series battery is usually a 12.8V battery pack provided with shorter lead time and fixed size dimension.

EM E48100

US $1721.49

Low speed vehicle not only includes golf carts, folklifts, three wheelers, motocycles, but also electric scooters, hoverboards, AGV(Automatic Guided Vehicle), ATV(All-Terrain Vehicle), et cetera. These are mostly 12V and 48V with batteries in series – that is more replace-able and preferable when one battery goes down under acceptable price. Thus it can’t be just the 520*450*260mm on the EM E48100. We can use high current (5C) binding post(or 500A flat wiping Anderson) connector to help with series circuit connection, iron bar to help with seperation and stability, and maybe a simple SOH displayer.

Customer Review

They are very easy to install and very secure for my three-wheelers. So far so good, I think I will check later and see how the batteries are.

Asif H. A., India, 48V120Ah

I purchase the batteries(on boat power backup) from Easiness Energy every season and they solve problem without delay. Easy and simple.

Sam W., England, 11.1V13Ah

Fast delivery and quality product.

Michael B., Germany, 48V20Ah

It takes some time on shipping but I like their batteries. They design the batteries with the size I need and the interface I want. I really need the extension indicator. The batteries work well on my golf carts for now. Great talk with Mike and Benny. I’m sure I will make order next time.

Ana M., Spain, 48V75Ah

All batteries fit as designed very compact, lots of room for wiring. I mean to replace the starting battery(lead one) with lithium batteries since they are really lighter and run 4 hours longer than it used to. You can’t believe this is the work done by a 13 lbs battery on the 24V tracker boat. Worthy. The only thing is I have to another self tapping screws as the first one doesn’t work.
