12V And 24V Lithium Batteries
Drop-in LiFePO4 replacements for lead-acid, from an 8Ah UPS block to a 400Ah house bank, with IP65 cases and Bluetooth monitoring.
RV And Camping Power
12V and 24V LiFePO4 house banks from 100Ah to 400Ah, IP65, Bluetooth monitored, at about a third of the weight of lead-acid.
An RV house bank has two hard limits: what the locker will hold and what the axle will carry. Lead-acid loses on both, because half its rated capacity is unusable and all of its weight is real. The Sike 12V and 24V deep cycle range publishes case dimensions and weights on every product - 9.7 kg for a group 24 100Ah pack, 38 kg for a 400Ah - so the swap can be planned before anything is ordered.
Sector pain points
What Goes Wrong In This Sector
Half The Capacity Is Off Limits
Discharging lead-acid below 50% destroys it. A 200Ah lead-acid bank is really 100Ah, which is why the fridge stops overnight.
The Tray Decides Everything
Group 24 at 260x170x210 mm and group 31 at 330x172x240 mm exist for a reason. A pack that does not fit turns an upgrade into a fabrication job.
Alternator Charging Takes All Day
Lead-acid takes a trickle at the top of the charge. LiFePO4 accepts 0.5C to 1C, so a driving day actually refills the bank.
No Idea What The Bank Is Doing
Bluetooth monitoring on the deep cycle range gives state of charge, voltage and current in real time instead of a guess and a voltmeter.
What buyers need
What This Sector Actually Asks For
- A pack that fits the existing battery locker and tray
- Real usable capacity rather than a nameplate figure
- Weight low enough to keep the payload legal
- An IP65 case that survives damp, dust and vibration
- Charge acceptance that suits solar and alternator charging
- Monitoring the owner can read on a phone

Where Most Buyers In This Sector Start
How we work with you
From Enquiry To Repeat Supply
Measure The Locker
Internal dimensions and the existing battery group size decide the shortlist before anything else.
Total The Overnight Load
Fridge, lights, water pump, inverter loads and how many nights between charges.
Pick 12V Or 24V
Stay 12V if the appliances and charger are 12V; go 24V if you are specifying the whole system and want smaller cable.
Confirm Charging
Solar controller, DC-DC charger and shore charger all need a LiFePO4 profile. We check the models you name.
Order And Ship
UN38.3 and MSDS documentation travels with the shipment for road, sea or air freight.

FAQ
RV And Camping Power Questions
Which group size do I need?
Measure the tray. We publish group 24 at 260x170x210 mm and group 31 at 330x172x240 mm, plus larger 200Ah, 300Ah and 400Ah formats that have no lead-acid equivalent. Send the measurements and we will tell you what fits.
How many nights will a 100Ah pack run my fridge?
Take the fridge's daily watt-hours and divide into roughly 1280 Wh for a 12V 100Ah LiFePO4 pack, then allow for lights, pump and inverter losses. We will do that arithmetic with you if you send the appliance list.
Can I charge from the alternator?
Through a DC-DC charger with a LiFePO4 profile, yes, and that is the right way to do it. Connecting a lithium bank directly to an alternator can overload the alternator, because the pack will take every amp it is offered.
Is the case really waterproof?
The deep cycle range publishes IP65 - dust tight and protected against water jets - in an ABS case built for shock and vibration. It suits a vented locker or an underslung mount, not permanent submersion.
Will it work in winter?
Discharging is fine well below freezing. Charging below 0 degrees Celsius is what damages cells, so specify the heating option if the van will be charged in freezing conditions.
Do you ship to individual customers?
Our business is wholesale and OEM, so single-unit orders are handled case by case. Ask on WhatsApp with your destination and we will tell you honestly whether it is worth the freight.
